Apply PCI host-bridge window offsets to screen_info framebuffers. Fixes
invalid access to I/O memory.
Resources behind a PCI host bridge can be relocated by a certain offset
in the kernel's CPU address range used for I/O. The framebuffer memory
range stored in screen_info refers to the CPU addresses as seen during
boot (where the offset is 0). During boot up, firmware may assign a
different memory offset to the PCI host bridge and thereby relocating
the framebuffer address of the PCI graphics device as seen by the kernel.
The information in screen_info must be updated as well.
The helper pcibios_bus_to_resource() performs the relocation of the
screen_info's framebuffer resource (given in PCI bus addresses). The
result matches the I/O-memory resource of the PCI graphics device (given
in CPU addresses). As before, we store away the information necessary to
later update the information in screen_info itself.
Commit 78aa89d1dfba ("firmware/sysfb: Update screen_info for relocated
EFI framebuffers") added the code for updating screen_info. It is based
on similar functionality that pre-existed in efifb. Efifb uses a pointer
to the PCI resource, while the newer code does a memcpy of the region.
Hence efifb sees any updates to the PCI resource and avoids the issue.
v3:
- Only use struct pci_bus_region for PCI bus addresses (Bjorn)
- Clarify address semantics in commit messages and comments (Bjorn)
v2:
- Fixed tags (Takashi, Ivan)
- Updated information on efifb

Trigger full device recovery when the driver fails to restore device state
via engine reset and resume operations. This is necessary because, even if
submissions from a faulty context are blocked, the NPU may still process
previously submitted faulty jobs if the engine reset fails to abort them.
Such jobs can continue to generate faults and occupy device resources.
When engine reset is ineffective, the only way to recover is to perform
a full device recovery.

This fixes a potential race conditions in:
- ivpu_bo_unbind_locked() where we modified the shmem->sgt without
holding the dma_resv_lock().
- ivpu_bo_print_info() where we read the shmem->pages without
holding the dma_resv_lock().
Using dma_resv_lock() also protects against future syncronisation
issues that may arise when accessing drm_gem_shmem_object or

Refactor ivpu_cmdq_unregister() to ensure the doorbell is unregistered
before destroying the command queue. The NPU firmware requires doorbells
to be unregistered prior to command queue destruction.
If doorbell remains registered when command queue destroy command is sent
firmware will automatically unregister the doorbell, making subsequent
unregister attempts no-operations (NOPs).
Ensure compliance with firmware expectations by moving the doorbell
unregister call ahead of the command queue destruction logic,
thus preventing unnecessary NOP operation.

Signal vt subsystem to redraw console when switching to dummycon
with deferred takeover enabled. Makes the console switch to fbcon
and displays the available output.
With deferred takeover enabled, dummycon acts as the placeholder
until the first output to the console happens. At that point, fbcon
takes over. If the output happens while dummycon is not active, it
cannot inform fbcon. This is the case if the vt subsystem runs in
graphics mode.
A typical graphical boot starts plymouth, a display manager and a
compositor; all while leaving out dummycon. Switching to a text-mode
console leaves the console with dummycon even if a getty terminal
has been started.
Returning true from dummycon's con_switch helper signals the vt
subsystem to redraw the screen. If there's output available dummycon's
con_putc{s} helpers trigger deferred takeover of fbcon, which sets a
display mode and displays the output. If no output is available,
dummycon remains active.

When an entity from application B is killed, drm_sched_entity_kill()
removes all jobs belonging to that entity through
drm_sched_entity_kill_jobs_work(). If application A's job depends on a
scheduled fence from application B's job, and that fence is not properly
signaled during the killing process, application A's dependency cannot be
cleared.
This leads to application A hanging indefinitely while waiting for a
dependency that will never be resolved. Fix this issue by ensuring that
scheduled fences are properly signaled when an entity is killed, allowing
dependent applications to continue execution.

Since commit 559358282e5b ("drm/fb-helper: Don't use the preferred depth
for the BPP default"), RGB565 displays such as the CFAF240320X no longer
render correctly: colors are distorted and the content is shown twice
horizontally.
This regression is due to the fbdev emulation layer defaulting to 32 bits
per pixel, whereas the display expects 16 bpp (RGB565). As a result, the
framebuffer data is incorrectly interpreted by the panel.
Fix the issue by calling drm_client_setup_with_fourcc() with a format
explicitly selected based on the display's bits-per-pixel value. For 16
bpp, use DRM_FORMAT_RGB565; for other values, fall back to the previous
behavior. This ensures that the allocated framebuffer format matches the
hardware expectations, avoiding color and layout corruption.
Tested on a CFAF240320X display with an RGB565 configuration, confirming
correct colors and layout after applying this patch.

When a CL/CSD job times out, we check if the GPU has made any progress
since the last timeout. If so, instead of resetting the hardware, we skip
the reset and let the timer get rearmed. This gives long-running jobs a
chance to complete.
However, when `timedout_job()` is called, the job in question is removed
from the pending list, which means it won't be automatically freed through
`free_job()`. Consequently, when we skip the reset and keep the job
running, the job won't be freed when it finally completes.
This situation leads to a memory leak, as exposed in [1] and [2].
Similarly to commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when
GPU is still active"), this patch ensures the job is put back on the
pending list when extending the timeout.

On r6x2b6x2g6x2 displays not enough blank data is sent to blank the
entire screen. When support for these displays was added, the dirty
function was updated to handle the different amount of data, but
blanking was not, and remained hardcoded as 2 bytes per pixel.
This change applies almost the same algorithm used in the dirty function
to the blank function, but there is no fb available at that point, and
no concern about having to transform any data, so the dbidev pixel
format is always used for calculating the length.

The drm_gem_shmem_test_get_pages_sgt() gets a scatter-gather table using
the drm_gem_shmem_get_sg_table() function and rightfully calls
sg_free_table() on it. However, it's also supposed to kfree() the
returned sg_table, but doesn't.
This leads to a memory leak, reported by kmemleak. Fix it by adding a
kunit action to kfree the sgt when the test ends.

Nouveau is mostly designed in a way that it's expected that fences only
ever get signaled through nouveau_fence_signal(). However, in at least
one other place, nouveau_fence_done(), can signal fences, too. If that
happens (race) a signaled fence remains in the pending list for a while,
until it gets removed by nouveau_fence_update().
Should nouveau_fence_context_kill() run in the meantime, this would be
a bug because the function would attempt to set an error code on an
already signaled fence.
Have nouveau_fence_context_kill() check for a fence being signaled.

fixed reset signal polarity in jadard_dsi_probe() and jadard_prepare().
It was not done in jadard_unprepare() because of an incorrect assumption
about reset line handling in power off mode. After looking into the
datasheet, it now appears that before disabling regulators, the reset line
is deasserted first, and if reset_before_power_off_vcioo is true, then the
reset line is asserted.
Fix reset polarity by inverting gpiod_set_value() second argument in

Christian reports that 4K output using YUV420 encoding fails with the
following error:
Fatal Error, invalid HDMI vclk freq 593406
Modetest shows the following:
3840x2160 59.94 3840 4016 4104 4400 2160 2168 2178 2250 593407 flags: xxxx, xxxx,
drm calculated value -------------------------------------^
This indicates that there's a (1kHz) mismatch between the clock
calculated by the drm framework and the meson driver.
Relevant function call stack:
(drm framework)
-> meson_encoder_hdmi_atomic_enable()
-> meson_encoder_hdmi_set_vclk()
-> meson_vclk_setup()
The video clock requested by the drm framework is 593407kHz. This is
passed by meson_encoder_hdmi_atomic_enable() to
meson_encoder_hdmi_set_vclk() and the following formula is applied:
- the frequency is halved (which would be 296703.5kHz) and rounded down
to the next full integer, which is 296703kHz
- TMDS clock is calculated (296703kHz * 10)
- video encoder clock is calculated - this needs to match a table from
meson_vclk.c and so it doubles the previously halved value again
(resulting in 593406kHz)
- meson_vclk_setup() can't find (either directly, or by deriving it from
594000kHz * 1000 / 1001 and rounding to the closest integer value -
which is 593407kHz as originally requested by the drm framework) a
matching clock in it's internal table and errors out with "invalid
HDMI vclk freq"
Fix the division precision by switching the whole meson driver to use
unsigned long long (64-bit) Hz values for clock frequencies instead of
unsigned int (32-bit) kHz to fix the rouding error.

Fix the frequency returned to the user space by
the DRM_IVPU_PARAM_CORE_CLOCK_RATE GET_PARAM IOCTL.
The kernel driver returned CPU frequency for MTL and bare
PLL frequency for LNL - this was inconsistent and incorrect
for both platforms. With this fix the driver returns maximum
frequency of the NPU data processing unit (DPU) for all HW
generations. This is what user space always expected.
Also do not set CPU frequency in boot params - the firmware
does not use frequency passed from the driver, it was only
used by the early pre-production firmware.
With that we can remove CPU frequency calculation code.

This resolves two issues that were encountered where a driver was left

1. Cancelling context-abort of a job that is still executing and
is causing translation faults which is going to cause additional TDRs
2. Cancelling bottom-half of a DCT (duty-cycle throttling) request
which will cause a device to not be adjusted to an external frequency

This commit is a resubmission of commit 1fe1c66274fb ("drm/v3d: Fix
Indirect Dispatch configuration for V3D 7.1.6 and later"), which was
accidentally reverted by commit 91dae758bdb8 ("Merge tag
'drm-misc-next-2024-08-01' of https://gitlab.freedesktop.org/drm/misc/kernel
into drm-next"), likely due to an unfortunate conflict resolution.
From the original commit message:
```
`args->cfg[4]` is configured in Indirect Dispatch using the number of
batches. Currently, for all V3D tech versions, `args->cfg[4]` equals the
number of batches subtracted by 1. But, for V3D 7.1.6 and later, we must not
subtract 1 from the number of batches.
Implement the fix by checking the V3D tech version and revision.
Fixes several `dEQP-VK.synchronization*` CTS tests related to Indirect Dispatch.
```

drm_analog_tv_mode() and its variants return a drm_display_mode that
needs to be destroyed later one. The
drm_test_connector_helper_tv_get_modes_check() test never does however,
which leads to a memory leak.
Let's make sure it's freed.
