3 years agodrm/amdgpu: Add preferred mode in modeset when freesync video mode's enabled.

drm/amdgpu: Add preferred mode in modeset when freesync video mode's enabled.

[Why]
With kernel module parameter "freesync_video" is enabled, if the mode
is changed to preferred mode(the mode with highest rate), then Freesync
fails because the preferred mode is treated as one of freesync video

drm/amd/display: Add DC_FP helper to check FPU state

To fully isolate FPU operations in a single place, we must avoid
situations where compilers spill FP values to registers due to FP enable
in a specific C file. Note that even if we isolate all FPU functions in
a single file and call its interface from other files, the compiler
might enable the use of FPU before we call DC_FP_START. Nevertheless, it
is the programmer's responsibility to invoke DC_FP_START/END in the
correct place. To highlight situations where developers forgot to use
the FP protection before calling the DC FPU interface functions, we
introduce a helper that checks if the function is invoked under FP
protection. If not, it will trigger a kernel warning.

Changes cince V3:
- Rebase

Changes cince V2 (Christian):
- Do not use this_cpu_* between get/put_cpu_ptr().
- In the kernel documentation, better describe restrictions.
- Make dc_assert_fp_enabled trigger the ASSERT message.

Changes since V1:
- Remove fp_enable variables
- Rename dc_is_fp_enabled to dc_assert_fp_enabled

drm/amd/display: Fix Dynamic bpp issue with 8K30 with Navi 1X

Why:
In DCN2x, HW doesn't automatically divide MASTER_UPDATE_LOCK_DB_X
by the number of pipes ODM Combined.

How:
Set MASTER_UPDATE_LOCK_DB_X to the value that is adjusted by the
number of pipes ODM Combined.

drm/amdgpu: Fix out-of-bounds read when update mapping

TTM only alloc struct ttm_resource instead of struct ttm_range_mgr_node
for sysMem.

Now when we update mapping for such invalidated BOs, we might walk out
of bounds of struct ttm_resource.

Three possible fix:
1) Let sysMem manager alloc struct ttm_range_mgr_node, like
ttm_range_manager does.
2) Pass pages_addr to update_mapping function too, but need memset
pages_addr[] to zero when unpopulate.
3) Init amdgpu_res_cursor directly.

drm/amd/display: add update authentication interface

[why]
Previously to toggle authentication, we need to remove and
add the same display back with modified adjustment.
This method will toggle DTM state without actual hardware changes.
This is not per design and would cause potential issues in the long run.

[how]
We are creating a dedicated interface that does the same thing as
remove and add back the display without changing DTM state.

3 years agodrm/vmwgfx: Be a lot more flexible with MOB limits
Zack Rusin [Fri, 23 Jul 2021 16:51:52 +0000 (12:51 -0400)]
drm/vmwgfx: Be a lot more flexible with MOB limits

The code was trying to keep a strict limit on the amount of mob
memory that was used in the guest by making it match the host
settings. There's technically no reason to do that (guests can
certainly use more than the host can have resident in renderers
at the same time).

In particular this is problematic because our userspace is not
great at handling OOM conditions and running out of MOB space
results in GL apps crashing, e.g. gnome-shell likes to allocate
huge surfaces (~61MB for the desktop on 2560x1600 with two workspaces)
and running out of memory there means that the gnome-shell crashes
on startup taking us back to the login and resulting in a system
where one can not login in graphically anymore.

Instead of letting the userspace crash we can extend available
MOB space, we just don't want to use all of the RAM for graphics,
so we're going to limit it to half of RAM.

With the addition of some extra logging this should make the
"guest has been configured with not enough graphics memory"
errors a lot easier to diagnose in cases where the automatic
expansion of MOB space fails.

drm/vmwgfx: Cleanup logging

The code was using the old DRM logging functions, which made it

helpers include the driver name in the logs and make it explicit
which driver they're coming from. This allows us to standardize
our logging a bit and clean it up in the process.

vmwgfx is a little special because technically the hardware it's
running on can be anything from the last 12 years or so which is
why we need to include capabilities in the logs in the first
place or otherwise we'd have no way of knowing what were
