drm/tegra: Changes for v5.15-rc1
The bulk of these changes is a more modern ABI that can be efficiently
used on newer SoCs as well as older ones. The userspace parts for this
are available here:
- libdrm support: https://gitlab.freedesktop.org/tagr/drm/-/commits/drm-tegra-uabi-v8
- VAAPI driver: https://github.com/cyndis/vaapi-tegra-driver
In addition, existing userspace from the grate reverse-engineering
project has been updated to use this new ABI:
- X11 driver: https://github.com/grate-driver/xf86-video-opentegra
- 3D driver: https://github.com/grate-driver/grate
Other than that, there's also support for display memory bandwidth
management for various generations and a bit of cleanup.

When locking a region, we currently clamp to a PAGE_SIZE as the minimum
lock region. While this is valid for Midgard, it is invalid for Bifrost,
where the minimum locking size is 8x larger than the 4k page size. Add a
hardware definition for the minimum lock region size (corresponding to
KBASE_LOCK_REGION_MIN_SIZE_LOG2 in kbase) and respect it.

Mali virtual addresses are 48-bit. Use a u64 instead of size_t to ensure
we can express the "lock everything" condition as ~0ULL without
overflow. This code was silently broken on any platform where a size_t
is less than 48-bits; in particular, it was broken on 32-bit armv7
platforms which remain in use with panfrost. (Mainly RK3288)

In lock_region, simplify the calculation of the region_width parameter.
This field is the size, but encoded as ceil(log2(size)) - 1.
ceil(log2(size)) may be computed directly as fls(size - 1). However, we
want to use the 64-bit versions as the amount to lock can exceed
32-bits.
This avoids undefined (and completely wrong) behaviour when locking all
memory (size ~0). In this case, the old code would "round up" ~0 to the
nearest page, overflowing to 0. Since fls(0) == 0, this would calculate
a region width of 10 + 0 = 10. But then the code would shift by
(region_width - 11) = -1. As shifting by a negative number is undefined,
UBSAN flags the bug. Of course, even if it were defined the behaviour is
wrong, instead of locking all memory almost none would get locked.
The new form of the calculation corrects this special case and avoids
the undefined behaviour.

Building a randconfig here triggered:

This patch limits the ref_div_max value to 100, during the
calculation of PLL feedback reference divider. With current
value (128), the produced fb_ref_div value generates unstable
output at particular frequencies. Radeon driver limits this
value at 100.
On Oland, when we try to setup mode 2048x1280@60 (a bit weird,
I know), it demands a clock of 221270 Khz. It's been observed
that the PLL calculations using values 128 and 100 are vastly
different, and look like this:
+------------------------------------------+
|Parameter |AMDGPU |Radeon |
| | | |
+-------------+----------------------------+
|Clock feedback | |
|divider max | 128 | 100 |
|cap value | | |
| | | |
| | | |
+------------------------------------------+
|ref_div_max | | |
| | 42 | 20 |
| | | |
| | | |
+------------------------------------------+
|ref_div | 42 | 20 |
| | | |
+------------------------------------------+
|fb_div | 10326 | 8195 |
+------------------------------------------+
|fb_div | 1024 | 163 |
+------------------------------------------+
|fb_dev_p | 4 | 9 |
|frac fb_de^_p| | |
+----------------------------+-------------+
With ref_div_max value clipped at 100, AMDGPU driver can also
drive videmode 2048x1280@60 (221Mhz) and produce proper output
without any blanking and distortion on the screen.
PS: This value was changed from 128 to 100 in Radeon driver also, here:

schedule_delayed_work does not push back the work if it was already
scheduled before, so amdgpu_device_delay_enable_gfx_off ran ~100 ms
after the first time GFXOFF was disabled and re-enabled, even if GFXOFF
was disabled and re-enabled again during those 100 ms.
This resulted in frame drops / stutter with the upcoming mutter 41
release on Navi 14, due to constantly enabling GFXOFF in the HW and
disabling it again (for getting the GPU clock counter).
To fix this, call cancel_delayed_work_sync when the disable count
transitions from 0 to 1, and only schedule the delayed work on the
reverse transition, not if the disable count was already 0. This makes
sure the delayed work doesn't run at unexpected times, and allows it to
be lock-free.
v2:
* Use cancel_delayed_work_sync & mutex_trylock instead of
mod_delayed_work.
v3:
* Make amdgpu_device_delay_enable_gfx_off lock-free (Christian König)
v4:
* Fix race condition between amdgpu_gfx_off_ctrl incrementing
adev->gfx.gfx_off_req_count and amdgpu_device_delay_enable_gfx_off
checking for it to be 0 (Evan Quan)

For some reason we run into an use case where a BO is already pinned
into GTT, but should be pinned into VRAM|GTT again.
Handle that case gracefully as well.

[why]
dcn301_calculate_wm_and_dl() causes flickering when external monitor is
connected.
This issue has been fixed before by commit 0e4c0ae59d7e
("drm/amdgpu/display: drop dcn301_calculate_wm_and_dl for now"), however
part of the fix was gone after commit 2cbcb78c9ee5 ("Merge tag 'amd-drm-next-5.13-2021-03-23' of https://gitlab.freedesktop.org/agd5f/linux into drm-next").
[how]
Use dcn30_calculate_wm_and_dlg() instead as in the original fix.

In some cases when we unload driver, warning call trace
will show up in vram_mgr_fini which claims that LRU is not empty, caused
by the ttm bo inside delay deleted queue.
[How]
We should flush delayed work to make sure the delay deleting is done.
