Subject: [PATCH] drm: Make the per-driver file_operations struct const
The DRM layer keeps a copy of struct file_operations inside its
big driver struct... which prevents it from being consistent and static.
For consistency (and the general security objective of having such things
static), it's desirable to get this fixed.
This patch splits out the file_operations field to its own struct,
which is then "static const", and just stick a pointer to this into
the driver struct, making it more consistent with how the rest of the
kernel does this.

drm_wait_vblank must be DRM_UNLOCKED because otherwise it
will grab the drm_global_mutex and then go to sleep until the vblank
event it is waiting for. That can wreck havoc in the windowing system
because if one process issues this ioctl, it will block all other
processes for the duration of all vblanks between the current and the
one it is waiting for. In some cases it can block the entire windowing
system.
v2: incorporate comments received from Daniel Vetter and
Michel Daenzer.
v3/v4: after a lengty discussion with Daniel Vetter, it was concluded
that the only thing not yet protected with locks and atomic
ops is the write to dev->last_vblank_wait. It's only used in a
debug file in proc, and the current code already employs no
correct locking: the proc file only takes dev->struct_mutex,
whereas drm_wait_vblank implicitly took the drm_global_mutex.
Given all this, it's not worth bothering to try to fix
the locks at this time.

This was only the case if the GPU reset was triggered from the CS ioctl,
otherwise other processes could happily enter the CS ioctl and wreak havoc
during the GPU reset.
This is a little complicated because the GPU reset can be triggered from the
CS ioctl, in which case we're already holding the mutex, or from other call
paths, in which case we need to lock the mutex. AFAICT the mutex API doesn't
allow recursive locking or finding out the mutex owner, so we need to handle
this with helper functions which allow recursive locking from the same
process.

We need to redefine a connector as "connected" if it matches a window
in the host preferred GUI layout.
Otherwise "smart" window managers would turn on Xorg outputs that we don't
want to be on.
This reinstates the update_layout and adds the following information to
the modesetting system.
a) Connection status <-> Equivalent to real hardware connection status
b) Preferred mode <-> Equivalent to real hardware reading EDID
c) Host window position <-> Equivalent to a real hardware scanout address
dynamic register.
It should be noted that there is no assumption here about what should be
displayed and where. Only how to access the host windows.
This also bumps minor to signal availability of the new IOCTL.

The commit 47356eb672 introduced a
mechanism to record the backlight level only at disabling time, but it
also introduced a regression. Since intel_lvds_enable() may be called
without disabling (e.g. intel_lvds_commit() calls it unconditionally),
the backlight gets back to the last recorded value. For example, this
happens when you dim the backlight, close the lid and open the lid,
then the backlight suddenly goes to the brightest.
This patch fixes the bug by recording the backlight level always
when changed via intel_panel_set_backlight(). And,
intel_panel_{enable|disable}_backlight() call the internal function not
to update the recorded level wrongly.

that it doesn't have a PLL of its own and so shouldn't try to write the
main PLL regs. The use_pll_a field controls which PLL pipe 3 will
share, A or B. The core code will try to share PLLs with whichever pipe
has the same timings, rejecting the mode set if none is found. This
means that pipe 3 must always be set after one of the other pipes has
been configured with real PLL settings.

Well almost anyway. IVB has 3 planes, pipes, transcoders, and FDI
interfaces, but only 2 pipe PLLs. So two of the pipes must use the same
pipe timings (e.g. 2 DP plus one other, or two HDMI with the same mode
and one other, etc.).

I've just discussed this quickly with Chris on irc and it's probably
best to just kill the list_empty early bailout. gpu_idle isn't a

without adding anything onto these lists is e.g. pageflip. There are
probably more.

We currently only round up the userspace size to the next page. We
assume that userspace hasn't made a mistake and requested a zero-length
gem object and all through our internal code we then presume that every
object is backed by at least a single page. Fix that oversight and
report EINVAL back to userspace if they try to create a zero length
object.

The rps disabling code wasn't properly cancelling outstanding work
items. Also add a comment that explains why we're not racing with
the work item that could unmask interrupts - that piece of code

This patch closes the following race:
We get a PM interrupt A, mask it, set dev_priv->iir = PM_A and kick of the
work item. Scheduler isn't grumpy, so the work queue takes rps_lock,
grabs pm_iir = dev_priv->pm_iir and pm_imr = READ(PMIMR). Note that
pm_imr == pm_iir because we've just masked the interrupt we've got.
Now hw sends out PM interrupt B (not masked), we process it and mask
it. Later on the irq handler also clears PMIIR.
Then the work item proceeds and at the end clears PMIMR. Because
(local) pm_imr == pm_iir we have
pm_imr & ~pm_iir == 0
so all interrupts are enabled.
Hardware is still interrupt-happy, and sends out a new PM interrupt B.
PMIMR doesn't mask B (it does not mask anything), PMIIR is cleared, so
we get it and hit the WARN in the interrupt handler (because
dev_priv->pm_iir == PM_B).
That's why I've moved the
WRITE(PMIMR, 0)
up under the protection of the rps_lock. And write an uncoditional 0
to PMIMR, because that's what we'll do anyway.
This races looks much more likely because we can arbitrarily extend
the window by grabing dev->struct mutex right after the irq handler
has processed the first PM_B interrupt.

Quoting Chris Wilson's more concise description:
"Ah I think I see the problem. As you point out we only mask the current
interrupt received, so that if we have a task pending (and so IMR != 0) we
actually unmask the pending interrupt and so could receive it again before the
tasklet is finally kicked off by the grumpy scheduler."
We need the hw to issue PM interrupts A, B, A while the scheduler is hating us
and refuses to run the rps work item. On receiving PM interrupt A we hit the
WARN because
dev_priv->pm_iir == PM_A | PM_B
Also add a posting read as suggested by Chris to ensure proper ordering of the
writes to PMIMR and PMIIR. Just in case somebody weakens write ordering.
