5fd1674d21 qemu/osdep: Add huge page aligned support on LoongArch platform
On LoongArch kvm mode if transparent huge page wants to be enabled, base
address and size of memslot from both HVA and GPA view. And LoongArch
supports both 4K and 16K page size with Linux kernel, so transparent huge
page size is calculated from real page size rather than hardcoded size.

592d0bc030 remove unnecessary casts from uintptr_t
uintptr_t, or unsigned long which is equivalent on Linux I32LP64 systems,
is an unsigned type and there is no need to further cast to __u64 which is
another unsigned integer type; widening casts from unsigned integers
zero-extend the value.

729ba8e933 target/i386: pcrel: store low bits of physical address in data[0]
For PC-relative translation blocks, env->eip changes during the
execution of a translation block, Therefore, QEMU must be able to
recover an instruction's PC just from the TranslationBlock struct and
the instruction data with.  Because a TB will not span two pages, QEMU
stores all the low bits of EIP in the instruction data and replaces them
in x86_restore_state_to_opc.  Bits 12 and higher (which may vary between
executions of a PCREL TB, since these only use the physical address in
the hash key) are kept unmodified from env->eip.  The assumption is that
these bits of EIP, unlike bits 0-11, will not change as the translation
block executes.

Unfortunately, this is incorrect when the CS base is not aligned to a page.
Then the linear address of the instructions (i.e. the one with the
CS base addred) indeed will never span two pages, but bits 12+ of EIP
can actually change.  For example, if CS base is 0x80262200 and EIP =
0x6FF4, the first instruction in the translation block will be at linear
address 0x802691F4.  Even a very small TB will cross to EIP = 0x7xxx,
while the linear addresses will remain comfortably within a single page.

The fix is simply to use the low bits of the linear address for data[0],
since those don't change.  Then x86_restore_state_to_opc uses tb->cs_base
to compute a temporary linear address (referring to some unknown
instruction in the TB, but with the correct values of bits 12 and higher);
the low bits are replaced with data[0], and EIP is obtained by subtracting
again the CS base.

Huge thanks to Mark Cave-Ayland for the image and initial debugging,
and to Gitlab user @kjliew for help with bisecting another occurrence
of (hopefully!) the same bug.

It should be relatively easy to write a testcase that performs MMIO on
an EIP with different bits 12+ than the first instruction of the translation
block; any help is welcome.

a58506b748 target/i386: Do not re-compute new pc with CF_PCREL
With PCREL, we have a page-relative view of EIP, and an
approximation of PC = EIP+CSBASE that is good enough to
detect page crossings.  If we try to recompute PC after
masking EIP, we will mess up that approximation and write
a corrupt value to EIP.

We already handled masking properly for PCREL, so the
fix in b5e0d5d2 was only needed for the !PCREL path.

use as a file descriptor allows running qemu unprivileged
even when the user running qemu is not in the kvm group
on distributions where access to /dev/kvm is gated behind

qemu is able to open /dev/kvm and passes the file descriptor
to qemu).

435262605f vga: sort-of implement word and double-word access modes
Jazz Jackrabbit has a very unusual VGA setup, where it uses odd/even mode
with 256-color graphics.  Probably, it wants to use fast VRAM-to-VRAM
copies without having to store 4 copies of the sprites as needed in mode
X, one for each mod-4 alignment; odd/even mode simplifies the code a
lot if it's okay to place on a 160-pixels horizontal grid.

At the same time, because it wants to use double buffering (a la "mode X")
it uses byte mode, not word mode as is the case in text modes.  In order
to implement the combination of odd/even mode (plane number comes from
bit 0 of the address) and byte mode (use all bytes of VRAM, whereas word
mode only uses bytes 0, 2, 4,... on each of the four planes), we need
to separate the effect on the plane number from the effect on the address.

Implementing the modes properly is a mess in QEMU, because it would
change the layout of VRAM and break migration.  As an approximation,
shift right when the CPU accesses memory instead of shifting left when
the CRT controller reads it.  A hack is needed in order to write font data
properly (see comment in the code), but it works well enough for the game.

Because doubleword and chain4 modes are now independent, chain4 does not
assert anymore that the address is in range.  Instead it just returns
all ones and discards writes, like other modes.

3f83435042 vga: use latches in odd/even mode too
Jazz Jackrabbit uses odd/even mode with 256-color graphics.  This is
probably so that it can do very fast blitting with a decent resolution
(two pixels, compared to four pixels for "regular" mode X).

Accesses still use all planes (reads go to the latches and the game uses
read mode 1 so that the CPU always gets 0xFF; writes use the plane mask
register because the game sets bit 2 of the sequencer's memory mode
register).  For this to work, QEMU needs to use the code for latched
memory accesses in odd/even mode.  The only difference between odd/even
mode and "regular" planar mode is how the plane is computed in read mode
0, and how the planes are masked if the aforementioned bit 2 is reset.

It is almost enough to fix the game.  You also need to honor byte/word
mode selection, which is done in the next patch.

973a724eb0 vga: implement horizontal pel panning in graphics modes
This implements smooth scrolling, as used for example by Commander Keen
and Second Reality.

Unfortunately, this is not enough to avoid tearing in Commander Keen,
because sometimes the wrong start address is used for a frame.
On real EGA, the panning register is sampled on every line, while
the display start is latched for the next frame at the start of the
vertical retrace.  On real VGA, the panning register is also latched,
but at the end of the vertical retrace.  It looks like Keen exploits
this by only waiting for horizontal retrace when setting the display
start, but implementing it breaks the 256-color Keen games...

4156325cd3 mtest2make: stop disabling meson test timeouts
The mtest2make.py script passes the arg '-t 0' to 'meson test' which
disables all test timeouts. This is a major source of pain when running
in GitLab CI and a test gets stuck. It will stall until GitLab kills the
CI job. This leaves us with little easily consumable information about
the stalled test. The TAP format doesn't show the test name until it is
completed, and TAP output from multiple tests it interleaved. So we
have to analyse the log to figure out what tests had un-finished TAP
output present and thus infer which test case caused the hang. This is
very time consuming and error prone.

By allowing meson to kill stalled tests, we get a direct display of what
test program got stuck, which lets us more directly focus in on what
specific test case within the test program hung.

The other issue with disabling meson test timeouts by default is that it
makes it more likely that maintainers inadvertantly introduce slowdowns.
For example the recent-ish change that accidentally made migrate-test
take 15-20 minutes instead of around 1 minute.

The main risk of this change is that the individual test timeouts might
be too short to allow completion in high load scenarios. Thus, there is
likely to be some short term pain where we have to bump the timeouts for
certain tests to make them reliable enough. The preceeding few patches
raised the timeouts for all failures that were immediately apparent
in GitLab CI.

Even with the possible short term instability, this should still be a
net win for debuggability of failed CI pipelines over the long term.

7071795114 qtest: bump migration-test timeout to 8 minutes
The migration test should take between 1 min 30 and 2 mins on reasonably
modern hardware. The test is not especially compute bound, rather its
running time is dominated by the guest RAM size relative to the
bandwidth cap, which forces each iteration to take at least 30 seconds.
None the less under high load conditions with multiple QEMU processes
spawned and competing with other parallel tests, the worst case running
time might be somewhat extended. Bumping the timeout to 8 minutes gives
us good headroom, while still catching stuck tests relatively quickly.

52a21689cd .gitlab-ci.d/buildtest.yml: Work around htags bug when environment is large
Sometimes the CI "pages" job fails with a message like this from
htags:

$ htags -anT --tree-view=filetree -m qemu_init -t "Welcome to the QEMU sourcecode"
htags: Negative exec line limit = -371

This is due to a bug in hflags where if the environment is too large it
falls over:
https://lists.gnu.org/archive/html/bug-global/2024-01/msg00000.html

This happens to us because GitLab CI puts the commit message of the
commit under test into the CI_COMMIT_MESSAGE and/or CI_COMMIT_TAG_MESSAGE
environment variables, so the job will fail if the commit happens to
have a verbose commit message.

Work around the htags bug by unsetting these variables while running
htags.

2bcc91ecea tests/tcg/s390x: Test LOAD ADDRESS EXTENDED
Add a small test to prevent regressions. Userspace runs in primary
mode, so LAE should always set the access register to 0.

e072af19fc scripts/checkpatch: Support codespell checking
Add two spelling check options (--codespell and --codespellfile) to
enhance spelling check through dictionary, which copied the Linux
kernel's implementation in checkpatch.pl.

This check uses the dictionary at "/usr/share/codespell/dictionary.txt"
by default, if there is no dictionary specified under this path, it
will look for the dictionary of python3's codespell (This requires user
to add python3's path in environment variable $PATH, and to install
codespell by "pip install codespell").

7af0cc147c hw/s390x/ccw: Replace dirname() with g_path_get_dirname()
As commit 3e015d815b ("use g_path_get_basename instead of basename")
said, g_path_get_dirname() should be preferred over dirname() since
the former is a portable utility function that has the advantage of not
modifying the string argument.

Replace dirname() with g_path_get_dirname().

469897ed43 hw/s390x/ccw: Replace basename() with g_path_get_basename()
g_path_get_basename() is a portable utility function that has the
advantage of not modifying the string argument, so it should be
preferred over basename().

And also to avoid potential compile breakage with the Musl C library
similar to [1], replace basename() with g_path_get_basename().

7af51621b1 target/s390x/kvm/pv: Provide some more useful information if decryption fails
It's a common scenario to copy guest images from one host to another
to run the guest on the other machine. This (of course) does not work
with "secure execution" guests since they are encrypted with one certain
host key. However, if you still (accidentally) do it, you only get a
very user-unfriendly error message that looks like this:

 qemu-system-s390x: KVM PV command 2 (KVM_PV_SET_SEC_PARMS) failed:
  header rc 108 rrc 5 IOCTL rc: -22

Let's provide at least a somewhat nicer hint to the users so that they
are able to figure out what might have gone wrong.

There are elements sw_ipmap and sw_coremap, which is usd to speed
up irq injection flow. They are saved and restored in vmstate during
migration, indeed they can calculated from hw registers. Here
post_load is added for get sw_ipmap and sw_coremap from extioi hw
state.
