drm/amd/display: Mark dml30's UseMinimumDCFCLK() as noinline for stack usage

This function consumes a lot of stack space and it blows up the size of
dml30_ModeSupportAndSystemConfigurationFull() with clang:

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3542:6: error: stack frame size (2200) exceeds limit (2048) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than]
  void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
       ^
  1 error generated.

Commit a0f7e7f759cf ("drm/amd/display: fix i386 frame size warning")
aimed to address this for i386 but it did not help x86_64.

To reduce the amount of stack space that
dml30_ModeSupportAndSystemConfigurationFull() uses, mark
UseMinimumDCFCLK() as noinline, using the _for_stack variant for
documentation. While this will increase the total amount of stack usage
between the two functions (1632 and 1304 bytes respectively), it will
make sure both stay below the limit of 2048 bytes for these files. The
aforementioned change does help reduce UseMinimumDCFCLK()'s stack usage
so it should not be reverted in favor of this change.

drm/amd/display: Revert "Fallback to SW cursor if SubVP + cursor too big"

This reverts commit a4f1b04216023ff0f4cd89328b59ee6890248130 since
returning false in case of SubVP results in no cursor being visible on
desktop as there is no sw cursor fallback path on all platforms.

drm/amd/display: Correct I2C register offset

[Why]
I2C register name starts with 1, unlike other registers that start with
0. This creates a problem with the new register macro refactoring when
I2C HW objects are created in an array.

[How]
Correct I2C register offset by making a new macro to account for array
offset.

[why]

enumeration.

[how]
Remove conditionals for floor/ceil operations which are used frequently
in DML and add an assertion for invalid callers using zero granuality.
Fix existing callers that rely on 0 granularity.

UAPI Changes:

- Revert "drm/i915/dg2: Add preemption changes for Wa_14015141709"

  The intent of Wa_14015141709 was to inform us that userspace can no
  longer control object-level preemption as it has on past platforms
  (i.e., by twiddling register bit CS_CHICKEN1[0]).  The description of
  the workaround in the spec wasn't terribly well-written, and when we
  requested clarification from the hardware teams we were told that on the
  kernel side we should also probably stop setting
  FF_SLICE_CS_CHICKEN1[14], which is the register bit that directs the
  hardware to honor the settings in per-context register CS_CHICKEN1.  It
  turns out that this guidance about FF_SLICE_CS_CHICKEN1[14] was a
  mistake; even though CS_CHICKEN1[0] is non-operational and useless to
  userspace, there are other bits in the register that do still work and
  might need to be adjusted by userspace in the future (e.g., to implement
  other workarounds that show up).  If we don't set
  FF_SLICE_CS_CHICKEN1[14] in i915, then those future workarounds would
  not take effect.

drm/dp_mst: Avoid deleting payloads for connectors staying enabled

When an MST connector stays enabled during a commit the connector's MST
state needs to be added to the atomic state, but the corresponding MST
payload allocation shouldn't be set for deletion; fix such modesets by
ensuring the above even if the connector was already enabled before the
modeset.

The issue led to the following:

drm/ssd130x: Replace simple display helpers with the atomic helpers

The simple display pipeline is a set of helpers that can be used by DRM
drivers to avoid dealing with all the needed components and just define
a few functions to operate a simple display device with one full-screen
scanout buffer feeding a single output.

But it is arguable that this provides the correct level of abstraction
for simple drivers, and recently some have been ported from using these
simple display helpers to use the regular atomic helpers instead.

The rationale for this is that the simple display pipeline helpers don't
hide that much of the DRM complexity, while adding an indirection layer
that conflates the concepts of CRTCs and planes. This makes the helpers
less flexible and harder to be reused among different graphics drivers.

Also, for simple drivers, using the full atomic helpers doesn't require
a lot of additional code. So adding a simple display pipeline layer may
not be worth it.

For these reasons, let's follow that trend and make ssd130x a plain DRM
driver that creates its own primary plane, CRTC, enconder and connector.

drm/amdgpu: TA unload messages are not actually sent to psp when amdgpu is uninstalled

V1:
  The psp_cmd_submit_buf function is called by psp_hw_fini to send
TA unload messages to psp to terminate ras, asd and tmr. But when
amdgpu is uninstalled, drm_dev_unplug is called earlier than
psp_hw_fini in amdgpu_pci_remove, the calling order as follows:
static void amdgpu_pci_remove(struct pci_dev *pdev) {
drm_dev_unplug
......
amdgpu_driver_unload_kms->amdgpu_device_fini_hw->...
->.hw_fini->psp_hw_fini->...
->psp_ta_unload->psp_cmd_submit_buf
......
}
The program will return when calling drm_dev_enter in psp_cmd_submit_buf.

So the call to drm_dev_enter in psp_cmd_submit_buf should be
removed, so that the TA unload messages can be sent to the psp
when amdgpu is uninstalled.

V2:
1. Restore psp_cmd_submit_buf to its original code.
2. Move drm_dev_unplug call after amdgpu_driver_unload_kms in
   amdgpu_pci_remove.
3. Since amdgpu_device_fini_hw is called by amdgpu_driver_unload_kms,
   remove the unplug check to release device mmio resource in
   amdgpu_device_fini_hw before calling drm_dev_unplug.

drm/i915/uc: Support for version reduced and multiple firmware files

There was a misunderstanding in how firmware file compatibility should
be managed within i915. This has been clarified as:
  i915 must support all existing firmware releases forever
  new minor firmware releases should replace prior versions
  only backwards compatibility breaking releases should be a new file

This patch cleans up the single fallback file support that was added
as a quick fix emergency effort. That is now removed in preference to
supporting arbitrary numbers of firmware files per platform.

The patch also adds support for having GuC firmware files that are
named by major version only (because the major version indicates
backwards breaking changes that affect the KMD) and for having HuC
firmware files with no version number at all (because the KMD has no
interface requirements with the HuC).

For GuC, the driver will report via dmesg if the found file is older than
expected. For HuC, the KMD will no longer require updating for any new
HuC release so will not be able to report what the latest expected
version is.

Currently, when trying to suspend and resume with qxl device，
there are some error messages after resuming,
eventually caused to black screen and can't be recovered.

The first error message:
[   64.668577][    C3] [drm] driver is in bug mode

This error is due to guest qxl driver
will call qxl_reinit_memslots(qdev) during system resume,
but didn't call qxl_io_reset(qdev) before this,
Then will cause the QXL_IO_MEMSLOT_ADD operation to fail on QEMU,
qxl->guest_bug flag will be set，As a result,
the QXL device can't communicate with guest qxl driver through the IO port.

after fix the first error,can success to resume and login to desktop,
but shortly after that will observe the second error message :
[  353.095343][  T863] qxl 0000:00:02.0: object_init failed for (262144, 0x00000001)
[  353.096660][  T863] [drm:qxl_gem_object_create [qxl]] *ERROR* Failed to allocate GEM object (260852, 1, 4096, -12)
[  353.097277][  T863] [drm:qxl_alloc_ioctl [qxl]] *ERROR* qxl_alloc_ioctl: failed to create gem ret=-12
[  368.197538][  T863] qxl 0000:00:02.0: object_init failed for (3149824, 0x00000001)
[  368.197541][  T863] [drm:qxl_alloc_bo_reserved [qxl]] *ERROR* failed to allocate VRAM BO

The problem is caused by calling qxl_ring_init_hdr(qdev->release_ring)
in qxl_drm_resume() function.
When do QXL_IO_RESET,QEMU will call init_qxl_ram(),
so params like prod,cons,notify_on_cons and notify_on_prod
will be set to default value.
Ring push/pop actions for release_ring can be performed normally.
But call qxl_ring_init_hdr(qdev->release_ring)
will eventually set notify_on_prod to number of QXL_RELEASE_RING_SIZE,
affect the value of notify in qxl_push_free_res() function always be false,
QEMU will no longer send events of QXL_INTERRUPT_DISPLAY to the
guest qxl driver，so qxl_ring_pop() will never been called anymore，
and can't do dma_fence_signal(),result to ttm_bo_wait_ctx(bo, ctx)
always return EBUSY,fail to call qxl_bo_create().

Test scenario:
1) start virtual machine with qemu command "-device qxl-vga"
2) click suspend botton to enter suspend mode
3) resume and observe the error message in kernel logs,screen will be black

Let's fix this by reset io and remove the qxl_ring_init_hdr calling.

drm/bochs: fix blanking

VGA_IS1_RC is the color mode register (VGA_IS1_RM the one for monochrome
mode, note C vs. M at the end).  So when using VGA_IS1_RC make sure the
vga device is actually in color mode and set the corresponding bit in the
misc register.

Reproducible when booting VMs in UEFI mode with some edk2 versions (edk2
fix is on the way too).  Doesn't happen in BIOS mode because in that
case the vgabios already flips the bit.

drm/virtio: set fb_modifiers_not_supported

Without this, the drm core advertises LINEAR modifier which is
incorrect.

Also userspace virgl does not support modifiers.  For example, it causes
chrome on ozone/drm to fail with "Failed to create scanout buffer".

drm/sun4i: tv: Add missing reset assertion

The reset line is deasserted at bind, and asserted if we ever encounter an
error there. However, it's never asserted in unbind which will lead to a
resource unbalance.

drm/sun4i: tv: Rename error label

The other error labels in sun4i_tv_bind() are named after the task they
perform (err_disable_clk to call clk_disable_unprepare for example).

However, the err_cleanup_connector is named after the calling site
(drm_connector_init failing) and will actually cleanup the encoder. Let's
rename it to err_cleanup_encoder to be consistent.
