Revert "drm/amdgpu: remove TOPDOWN flags when allocating VRAM in large bar system"

This reverts commit c105518679b6e87232874ffc989ec403bee59664.

This patch disables the TOPDOWN flag for APU and few dGPU cards
which has the VRAM size equal to the BAR size.

When we enable the TOPDOWN flag, we get the free blocks at
the highest available memory region and we don't split the
lower order blocks. This change is required to keep off
the fragmentation related issues particularly in ASIC
which has VRAM space <= 500MiB

Hence, we are reverting this patch.

The buffer object backing the fbdev emulation got pinned twice: by the
fb_probe helper radeon_fbdev_create_pinned_object() and the modesetting
code when the framebuffer got displayed. It only got unpinned once by
the fbdev helper radeon_fbdev_destroy_pinned_object(). Hence TTM's BO-

13 months agodrm/amd/display: Skip DPP DTO update if root clock is gated
Nicholas Kazlauskas [Fri, 28 Apr 2023 15:23:50 +0000 (11:23 -0400)]
drm/amd/display: Skip DPP DTO update if root clock is gated

[Why]
Hardware implements root clock gating by utilizing the DPP DTO registers
with a special case of DTO enabled, phase = 0, modulo = 1. This
conflicts with our policy to always update the DPPDTO for cases where
it's expected to be disabled.

The pipes unexpectedly enter a higher power state than expected because
of this programming flow.

[How]
Guard the upper layers of HWSS against this hardware quirk with
programming the register with an internal state flag in DCCG.

While technically acting as global state for the DCCG, HWSS shouldn't be
expected to understand the hardware quirk for having DTO disabled
causing more power than DTO enabled with this specific setting.

This also prevents sequencing errors from occuring in the future if
we have to program DPP DTO in multiple locations.

13 months agodrm/amd: Make sure image is written to trigger VBIOS image update flow
Mario Limonciello [Wed, 7 Jun 2023 06:41:22 +0000 (01:41 -0500)]
drm/amd: Make sure image is written to trigger VBIOS image update flow

The VBIOS image update flow requires userspace to:
1) Write the image to `psp_vbflash`
2) Read `psp_vbflash`
3) Poll `psp_vbflash_status` to check for completion

If userspace reads `psp_vbflash` before writing an image, it's
possible that it causes problems that can put the dGPU into an invalid
state.

Explicitly check that an image has been written before letting a read
succeed.

drm/amd/display: Program OTG vtotal min/max selectors unconditionally for DCN1+

For FPO/FAMS, DMCUB will try to change the output timings by writing to
the OTG registers. However, the timings written directly to the OTG
registers will not be honoured unless VMIN/VMAX selector registers are
programmed with the right bits and trigger source is selected correctly.
Proper solution needs to go into DMCUB but will require additional state
tracking to ensure that the selectors are set and reset correctly as per
driver state. Until fix is merged into firmware, apply the workaround in
driver to unconditionally write OTG vmin/vmax selectors.

This reverts commit 047783cdd5f604d87398236beb4971abb4d43293 since it
causes higher power consumption for single display use case (4k60).

Also, this patch introduced a 35% performance drop in a Vulkan benchmark.

* The patch disabled the ODM-combination on most popular monitors, including 4K, 2K and FHD monitors at 60Hz.

* ODM-combination can halve the DPP clock to save power, that is the reason why we introduce ODM-combination, and the PM log shows single pipe consumes more power at 4K@60Hz.

* ODM-combination has 2 de-tiled buffer involved, which provides longer self-sustained time, that benefit to the memory power optimization.
