Zhenyu Wang 3bad078183 drm/i915: Probe for PCH chipset type
PCH is the new name for south bridge from Ironlake/Sandybridge,
which contains most of the display outputs except eDP. This one
adds a probe function to detect current PCH type, and method to
detect Cougarpoint PCH.

Zhao Yakui edcb49ca34 drm/i915: Fix legacy BLC event for pipe A
OpRegion event on 965G requires legacy BLC event enabled in pipe stat. As LVDS
could be on either pipe now, we should enable BLC event on both pipe. If fail to
do so, we couldn't handle the brightness request triggered from graphics
opregion.

Eric Anholt 6443170f6d drm/i915: Remove dead KMS encoder save/restore code.
This was brought over from UMS, and used for a while until we decided
that drm_helper_resume_force_mode was easier and more reliable, since
it didn't require duplicating all the code deleted here.  We just
forgot to delete all that junk for a while.

Dave Airlie ce227c4183 drm/radeon/kms: only change mode when coherent value changes.
On X startup we were getting a flicker where there shouldn't have been one.
the X DDX calls the kernel to set the properties to the same values (yes
it could be smarter), however the kernel was doing a pointless modeset then,
making my nice smooth boot ugly.

Zhenyu Wang 335af9a235 drm/i915: change intel_ddc_get_modes() function parameters
This one replaces original param for intel_ddc_get_modes() with
DRM connector and i2c bus adapter instead. With explicit params,
we won't require that a single driver structure must hold connector
and DDC bus reference, which ease the conversion to splitted encoder/
connector model.

It also clears up for some cases that we would steal other DDC bus
for mode probe, like VGA analog DDC probe for DVI-I. Also it fixed
a bug in old DVI-I probe handling, that failed to restore origin
analog GPIO port.

In load detection, connector's encoder assignment must be kept

Zhao Yakui fb8b5a39b6 drm/i915: Configure the TV sense state correctly on GM45 to make TV detection reliable
The TV detection logic is not reliable on the Cantiga platform.
Sometimes the TV will be misdetected as the following two cases:
- TV is misdetected on some laptops. e.g. There is no TV connector
port or no TV is attached. But the TV is shown as connected.
- TV connector type is misdetected. e.g. the component TV is
attached, but the TV is shown as S-video type.

According to the hardware requirement, the TV sense state bits of TV DAC
register should be cleared to zero on Cantiga platfrom.

Dave Airlie 4abe35204a drm/kms/fb: use slow work mechanism for normal hotplug also.
a) slow work is always used now for any fbcon hotplug, as its not
   a fast task and is more suited to being ran under slow work.

b) attempt to not do any fbdev changes when X is running as we'll
   just mess it up. This hooks set_par to hopefully do the changes
   once X hands control to fbdev.

This also adds the nouveau/intel hotplug support.

Dave Airlie 5c4426a782 drm/kms/fb: add polling support for when nothing is connected.
When we are running in a headless environment we have no idea what
output the user might plug in later, we only have hotplug detect
from the digital outputs. So if we detect no connected outputs at
initialisation, start a slow work operation to poll every 5 seconds
for an output.

this is only hooked up for radeon so far, on hw where we have full
hotplug detection there is no need for this.

Dave Airlie 386516744b drm/fb: fix fbdev object model + cleanup properly.
The fbdev layer in the kms code should act like a consumer of the kms services and avoid having relying on information being store in the kms core structures in order for it to work.

This patch

a) removes the info pointer/psuedo palette from the core drm_framebuffer structure and moves it to the fbdev helper layer, it also removes the core drm keeping a list of kernel kms fbdevs.
b) migrated all the fb helper functions out of the crtc helper file into the fb helper file.
c) pushed the fb probing/hotplug control into the driver
d) makes the surface sizes into a structure for ease of passing
This changes the intel/radeon/nouveau drivers to use the new helper.

Pauli Nieminen 1403b1a38e drm/ttm: add pool wc/uc page allocator V3
On AGP system we might allocate/free routinely uncached or wc memory,
changing page from cached (wb) to uc or wc is very expensive and involves
a lot of flushing. To improve performance this allocator use a pool
of uc,wc pages.

Pools are protected with spinlocks to allow multiple threads to allocate pages
simultanously. Expensive operations are done outside of spinlock to maximize
concurrency.

Pools are linked lists of pages that were recently freed. mm shrink callback
allows kernel to claim back pages when they are required for something else.

Fixes:
* set_pages_array_wb handles highmem pages so we don't have to remove them
  from pool.
* Add count parameter to ttm_put_pages to avoid looping in free code.
* Change looping from _safe to normal in pool fill error path.
* Initialize sum variable and make the loop prettier in get_num_unused_pages.

* Moved pages_freed reseting inside the loop in ttm_page_pool_free.
* Add warning comment about spinlock context in ttm_page_pool_free.

Based on Jerome Glisse's and Dave Airlie's pool allocator.

Jerome Glisse 90aca4d274 drm/radeon/kms: simplify & improve GPU reset V2
This simplify and improve GPU reset for R1XX-R6XX hw, it's
not 100% reliable here are result:
- R1XX/R2XX works bunch of time in a row, sometimes it
  seems it can work indifinitly
- R3XX/R3XX the most unreliable one, sometimes you will be
  able to reset few times, sometimes not even once
- R5XX more reliable than previous hw, seems to work most
  of the times but once in a while it fails for no obvious
  reasons (same status than previous reset just no same
  happy ending)
- R6XX/R7XX are lot more reliable with this patch, still
  it seems that it can fail after a bunch (reset every
  2sec for 3hour bring down the GPU & computer)

This have been tested on various hw, for some odd reasons
i wasn't able to lockup RS480/RS690 (while they use to
love locking up).

Note that on R1XX-R5XX the cursor will disapear after
lockup haven't checked why, switch to console and back
to X will restore cursor.

Next step is to record the bogus command that leaded to
the lockup.

V2 Fix r6xx resume path to avoid reinitializing blit
module, use the gpu_lockup boolean to avoid entering
inifinite waiting loop on fence while reiniting the GPU

Jerome Glisse 225758d8ba drm/radeon/kms: fence cleanup + more reliable GPU lockup detection V4
This patch cleanup the fence code, it drops the timeout field of
fence as the time to complete each IB is unpredictable and shouldn't
be bound.

The fence cleanup lead to GPU lockup detection improvement, this
patch introduce a callback, allowing to do asic specific test for
lockup detection. In this patch the CP is use as a first indicator
of GPU lockup. If CP doesn't make progress during 1second we assume
we are facing a GPU lockup.

To avoid overhead of testing GPU lockup frequently due to fence
taking time to be signaled we query the lockup callback every
500msec. There is plenty code comment explaining the design & choise
inside the code.

This have been tested mostly on R3XX/R5XX hw, in normal running
destkop (compiz firefox, quake3 running) the lockup callback wasn't
call once (1 hour session). Also tested with forcing GPU lockup and
lockup was reported after the 1s CP activity timeout.

V2 switch to 500ms timeout so GPU lockup get call at least 2 times
   in less than 2sec.
V3 store last jiffies in fence struct so on ERESTART, EBUSY we keep
   track of how long we already wait for a given fence
V4 make sure we got up to date cp read pointer so we don't have
   false positive

Adam Jackson 7a37435008 drm/edid: Add secondary GTF curve support
Before CVT-R, some monitors would advertise support for an alternative
GTF formula with lower blanking intervals.  Correctly identify such
monitors, and use the alternative formula when generating modes for
them.

Note that we only do this for "standard" timing descriptors (tuples of
hsize in characters / aspect ratio / vertical refresh).  Range-based
mode lists still only refer to the primary GTF curve.  It would be
possible to do better for the latter case, but monitors are required to
support the primary curve over the entire advertised range, so all it
would win you is a lower pixel clock and therefore possibly better image
quality on analog links.

Tejun Heo 5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

Eric Anholt 21d40d37ec drm/i915: Rename intel_output to intel_encoder.
The intel_output naming is inherited from the UMS code, which had a
structure of screen -> CRTC -> output.  The DRM code has an additional
notion of encoder/connector, so the structure is screen -> CRTC ->
encoder -> connector.  This is a useful structure for SDVO encoders
which can support multiple connectors (each of which requires
different programming in the one encoder and could be connected to
different CRTCs), or for DVI-I, where multiple encoders feed into the
connector for whether it's used for digital or analog.  Most of our
code is encoder-related, so transition it to talking about encoders
before we start trying to distinguish connectors.

This patch is produced by sed s/intel_output/intel_encoder/ over the
driver.

Clemens Ladisch a5ee4eb754 PCI quirk: RS780/RS880: work around missing MSI initialization
AMD says in section 2.5.4 (GFX MSI Enable) of #43291 (AMD 780G Family
Register Programming Requirements):

  The SBIOS must enable internal graphics MSI capability in GCCFG by
  setting the following: NBCFG.NB_CNTL.STRAP_MSI_ENABLE='1'

Quite a few BIOS writers misinterpret this sentence and think that
enabling MSI is an optional feature.  However, clearing that bit just
prevents delivery of MSI messages but does not remove the MSI PCI
capabilities registers, and so leaves these devices unusable for any
driver that attempts to use MSI.

Setting that bit is not possible after the BIOS has locked down the
configuration registers, so we have to manually disable MSI for the
affected devices.

This fixes the codec communication errors in the HDA driver when
accessing the HDMI audio device, and allows us to get rid of the
overcautious quirk in radeon_irq_kms.c.

Eric Anholt 6e6c822868 drm/i915: Stop trying to use ACPI lid status to determine LVDS connection.
I've been getting more and more quirk reports about this.  It seems
clear at this point that other OSes are not using this for determining
whether the integrated panel should be turned on, and it is not
reliable for doing so.  Better to light up an unintended panel than to
not light up the only usable output on the system.

Daniel Vetter fe305198d4 drm/intel: fix up set_tiling for untiled->tiled transition
Bug introduced in

commit 10ae9bd25a
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Mon Feb 1 13:59:17 2010 +0100

    drm/i915: blow away userspace mappings before fence change

The problem is that when there's no fence reg assigned and the object
is mapped at a fenceable offset in the gtt, the userspace mappings won't
be torn down. Which happens on untiled->tiled transition quite often
on 4th gen and later because there fencing does not have any special
alignment constraints (as opposed to 2nd and 3rd gen on which I've tested
the original commit).

VRAM->system is a synchronous operation: it involves scheduling a
VRAM->TT DMA transfer and stalling the CPU until it's finished so that
we can unbind the new memory from the translation tables. VRAM->TT can
always be performed asynchronously, even if TT is already full and we
have to move something out of it.

Additionally, allowing VRAM->system behaves badly under heavy memory
pressure because once we run out of TT, stuff starts to be moved back
and forth between VRAM and system, and the TT contents are hardly
renewed.

Ben Skeggs d544d623c5 drm/nv50: fix connector table parsing for some cards
The connector table index in the DCB entry for each output type is an
index into the connector table, and does *not* necessarily match up
with what was previously called "index" in the connector table entries
themselves.

Not real sure what that index is exactly, renamed to "index2" as we
still use it to prevent creating multiple TV connectors.

This makes nouveau recognise and report more kinds of PGRAPH errors, as
well as prevent GPU lockups resulting from some of them.

Lots of guesswork was involved and some part of this is probably
incorrect. Some potential-lockuop situations are handled by just
resetting a whole PGRAPH subunit, which doesn't sound like a "proper"
solution, but seems to work just fine... for now.

Emese Revfy 52cf25d0ab Driver core: Constify struct sysfs_ops in struct kobj_type
Constify struct sysfs_ops.

This is part of the ops structure constification
effort started by Arjan van de Ven et al.

Benefits of this constification:

 * prevents modification of data that is shared
   (referenced) by many other structure instances
   at runtime

 * detects/prevents accidental (but not intentional)
   modification attempts on archs that enforce
   read-only kernel data at runtime

 * potentially better optimized code as the compiler
   can assume that the const data cannot be changed

 * the compiler/linker move const data into .rodata
   and therefore exclude them from false sharing

Passing the attribute to the low level IO functions allows all kinds
of cleanups, by sharing low level IO code without requiring
an own function for every piece of data.

Also drivers can extend the attributes with own data fields
and use that in the low level function.

This makes the class attributes the same as sysdev_class attributes
and plain attributes.

This will allow further cleanups in drivers.

Linus Torvalds b8fa05719b Revert "lib: build list_sort() only if needed"
This reverts commit a069c266ae.

It turns ou that not only was it missing a case (XFS) that needed it,
but perhaps more importantly, people sometimes want to enable new
modules that they hadn't had enabled before, and if such a module uses
list_sort(), it can't easily be inserted any more.

So rather than add a "select LIST_SORT" to the XFS case, just leave it
compiled in.  It's not all _that_ big, after all, and the inconvenience
isn't worth it.

Dave Airlie 6a9ee8af34 vga_switcheroo: initial implementation (v15)
Many new laptops now come with 2 gpus, one to be used for low power
modes and one for gaming/on-ac applications. These GPUs are typically
wired to the laptop panel and VGA ports via a multiplexer unit which
is controlled via ACPI methods.

4 combinations of systems typically exist - with 2 ACPI methods.
Intel/ATI - Lenovo W500/T500 - use ATPX ACPI method
ATI/ATI - some ASUS - use ATPX ACPI Method
Intel/Nvidia - - use _DSM ACPI method
Nvidia/Nvidia -  - use _DSM ACPI method.

TODO:
This patch adds support for the ATPX method and initial bits
for the _DSM methods that need to written by someone with
access to the hardware.
Add a proper non-debugfs interface - need to get some proper
testing first.

v2: add power up/down support for both devices
on W500 puts i915/radeon into D3 and cuts power to radeon.

v3: redo probing methods, no DMI list, drm devices call to
register with switcheroo, it tries to find an ATPX method on
any device and once there is two devices + ATPX it inits the
switcher.

v4: ATPX msg handling using buffers - should work on more machines

v5: rearchitect after more mjg59 discussion - move ATPX handling to
    radeon driver.

v6: add file headers + initial nouveau bits (to be filled out).

v7: merge delayed switcher code.

v8: avoid suspend/resume of gpu that is off

v9: rearchitect - mjg59 is always right. - move all ATPX code to
radeon, should allow simpler DSM also proper ATRM handling

v10: add ATRM support for radeon BIOS, add mutex to lock vgasr_priv

v11: fix bug in resuming Intel for 2nd time.

v12: start fixing up nvidia code blindly.

v13: blindly guess at finishing nvidia code

v14: remove radeon audio hacks - fix up intel resume more like upstream

v15: clean up printks + remove unnecessary igd/dis pointers

mount debugfs

/sys/kernel/debug/vgaswitcheroo/switch - should exist if ATPX detected
 + 2 cards.

DIS - immediate change to discrete
IGD - immediate change to IGD

This commit "disabled" audio on RV710 and RV740 only, leaving RV770 and RV730.
The order is: CHIP_RV770 < CHIP_RV730 < CHIP_RV710 < CHIP_RV740.

It is not needed anway, as we do not even try to enable audio on RV770 and
newer. We call initializing function in r600.c only, not in rv770.c.

If there is something causing green tinges, it's HDMI mode setting for encoder
and I will try to debug that.

Dave Airlie 566d84d172 drm/radeon: r100/r200 ums: block ability for userspace app to trash 0 page and beyond
radeon's have a special ability to passthrough writes in their internal
memory space directly to PCI, this ability means that if some of the internal
surfaces like the depth buffer point at 0x0, any writes to these will
go directly to RAM at 0x0 via PCI busmastering.

Now mesa used to always emit clears after emitting state, since the
radeon mesa driver was refactored a year or more ago, it was found it
could generate a clear request without ever sending any setup state to the
card. So the clear would attempt to clear the depth buffer at 0x0, which
would overwrite main memory at this point. fs corruption ensues.

Also once one app did this correctly, it would never get set back to 0
making this messy to reproduce.

The kernel should block this from happening as mesa runs without privs,
though it does require the user be connected to the current running X session.

This patch implements a check to make sure the depth offset has been set
before a depth clear occurs and if it finds one it prints a warning and
ignores the depth clear request. There is also a mesa fix to avoid sending
the badness going into mesa.

This only affects r100/r200 GPUs in user modesetting mode.

Jesse Barnes 469d129664 drm/i915: enable/disable LVDS port at DPMS time
It would be good to disable the LVDS port when we shut down the panel
to save power.  We haven't done so until now because we had trouble
getting the right LVDS parameters from the BIOS.  I think we're past
that now, so enabling and disabling the port should be safe, though it
would probably be made cleaner with some additional changes to the
display code, where we also bang on the LVDS reg to set the pairing
correctly etc.

Seems to save a bit of power (up to 300mW in my basic wattsup
meter testing).

Fixing this cause the code to indent way to much, so I've extracted
the flushing_list processing logic into its on function.

Daniel Vetter ae3db24aab drm/i915: extract fence stealing code
The spaghetti logic in there tripped up my brain's code parser for a
few secs. Prevent this from happening again by extracting the fence
stealing code into a seperate functions. IMHO this slightly clears up
the code flow.

v2: Beautified according to ickle's comments.
v3: ickle forgot to flush his comment queue ... Now there's also a
we-are-paranoid BUG_ON in there.
v4: I've forgotten to switch on my brain when doing v3. Now the BUG_ON
actually checks something useful.
v5: Clean up a stale comment as noted by Eric Anholt.

Daniel Vetter 798750e30d drm/i915: reuse i915_gem_object_put_fence_reg for fence stealing code
This has a few functional changes against the old code:

* a few more unnecessary loads and stores to the drm_i915_fence_reg
  objects. Also an unnecessary store to the hw fence register.

* zaps any userspace mappings before doing other flushes. Only changes
  anything when userspace does racy stuff against itself.

* also flush GTT domain. This is a noop, but still try to keep the
  bookkeeping correct.

Zhenyu Wang 1f7a6e372e drm/i915: Add dependency on the intel agp module
See http://bugzilla.kernel.org/show_bug.cgi?id=15021

Make sure that the appropriate AGP module is loaded and probed before
trying to set up the DRM.  The DRM already depends on the AGP core,
but in this case we know the specific AGP driver we need too, and can
help users avoid the trap of loading the AGP driver after the DRM
driver.
