[PATCH v7 00/45] Recover from failure to probe GPU

[PATCH v7 00/45] Recover from failure to probe GPU

[Mario Limonciello]

One of the first thing that KMS drivers do during initialization is
destroy the system firmware framebuffer by means of
`drm_aperture_remove_conflicting_pci_framebuffers`

This means that if for any reason the GPU failed to probe the user
will be stuck with at best a screen frozen at the last thing that
was shown before the KMS driver continued it's probe.

The problem is most pronounced when new GPU support is introduced
because users will need to have a recent linux-firmware snapshot
on their system when they boot a kernel with matching support.

However the problem is further exaggerated in the case of amdgpu because
it has migrated to "IP discovery" where amdgpu will attempt to load
on "ALL" AMD GPUs even if the driver is missing support for IP blocks
contained in that GPU.

IP discovery requires some probing and isn't run until after the
framebuffer has been destroyed.

This means a situation can occur where a user purchases a new GPU not
yet supported by a distribution and when booting the installer it will
"freeze" even if the distribution doesn't have the matching kernel support
for those IP blocks.

The perfect example of this is Ubuntu 22.10 and the new dGPUs just
launched by AMD.  The installation media ships with kernel 5.19 (which
has IP discovery) but the amdgpu support for those IP blocks landed in
kernel 6.0. The matching linux-firmware was released after 22.10's launch.
The screen will freeze without nomodeset. Even if a user manages to install
and then upgrades to kernel 6.0 after install they'll still have the
problem of missing firmware, and the same experience.

This is quite jarring for users, particularly if they don't know
that they have to use "nomodeset" to install.

To help the situation make changes to GPU discovery:
1) Delay releasing the firmware framebuffer until after early_init
completed.  This will help the situation of an older kernel that doesn't
yet support the IP blocks probing a new GPU. IP discovery will have failed.
2) Request loading all PSP, VCN, SDMA, SMU, DMCUB, MES and GC microcode
into memory during early_init. This will help the situation of new enough
kernel for the IP discovery phase to otherwise pass but missing microcode
from linux-firmware.git.

v6->v7:
 * Pick up tags
 * Fix PSP TAv1 handling to match previous behavior (securedisplay_context
   only is set on PSPv10 and PSPv12/Renoir)
v5->v6:
 * Fix arguments for amdgpu_ucode_release to allow clearing pointer
 * Fix whitespace mistake in VCN
 * Pick up tags
v4->v5:
 * Rename amdgpu_ucode_load to amdgpu_ucode_request
 * Add and utilize amdgpu_ucode_release throughout existing patches
 * Update all amdgpu code to stop using request_firmware and
   release_firmware for microcode
 * Drop export of amdgpu_ucode_validate outside of amdgpu_ucode.c
 * Pick up relevant tags for some patches
v3->v4:
 * Rework to delay framebuffer release until early_init is done
 * Make IP load microcode during early init phase
 * Add SMU and DMCUB checks for early_init loading
 * Add some new helper code for wrapping request_firmware calls (needed for
   early_init to return something besides -ENOENT)
v2->v3:
 * Pick up tags for patches 1-10
 * Rework patch 11 to not validate during discovery
 * Fix bugs with GFX9 due to gfx.num_gfx_rings not being set during
   discovery
 * Fix naming scheme for SDMA on dGPUs
v1->v2:
 * Take the suggestion from v1 thread to delay the framebuffer release
   until ip discovery is done. This patch is CC to stable to that older
   stable kernels with IP discovery won't try to probe unknown IP.
 * Drop changes to drm aperature.
 * Fetch SDMA, VCN, MES, GC and PSP microcode during IP discovery.

[PATCH v7 01/45] drm/amd: Delay removal of the firmware framebuffer

[Mario Limonciello]

Removing the firmware framebuffer from the driver means that even
if the driver doesn't support the IP blocks in a GPU it will no
longer be functional after the driver fails to initialize.

This change will ensure that unsupported IP blocks at least cause
the driver to work with the EFI framebuffer.

[PATCH v7 02/45] drm/amd: Add a legacy mapping to "amdgpu_ucode_ip_version_decode"

[Mario Limonciello]

This will allow other parts of the driver that currently special
case firmware file names to before IP version style naming to just
have a single call to `amdgpu_ucode_ip_version_decode`.

[PATCH v7 05/45] drm/amd: Add a new helper for loading/validating microcode

[Mario Limonciello]

All microcode runs a basic validation after it's been loaded. Each
IP block as part of init will run both.

Introduce a wrapper for request_firmware and amdgpu_ucode_validate.
This wrapper will also remap any error codes from request_firmware
to -ENODEV.  This is so that early_init will fail if firmware couldn't
be loaded instead of the IP block being disabled.

[PATCH v7 08/45] drm/amd: Make SDMA firmware load failures less noisy.

[Mario Limonciello]

When firmware is missing we get failures at every step.
```
[    3.855086] amdgpu 0000:04:00.0: Direct firmware load for amdgpu/green_sardine_sdma.bin failed with error -2
[    3.855087] [drm:amdgpu_sdma_init_microcode [amdgpu]] *ERROR* SDMA: Failed to init firmware "amdgpu/green_sardine_sdma.bin"
[    3.855398] [drm:sdma_v4_0_early_init [amdgpu]] *ERROR* Failed to load sdma firmware!
```
Realistically we don't need all of these, a user can tell from the first one
that request_firmware emitted what happened. Drop the others.

[PATCH v7 09/45] drm/amd: Use `amdgpu_ucode_*` helpers for VCN

[Mario Limonciello]

The `amdgpu_ucode_request` helper will ensure that the return code for
missing firmware is -ENODEV so that early_init can fail.

The `amdgpu_ucode_release` helper is for symmetry.

[PATCH v7 10/45] drm/amd: Load VCN microcode during early_init

[Mario Limonciello]

Simplifies the code so that all VCN versions will get the firmware
name from `amdgpu_ucode_ip_version_decode` and then use this filename
to load microcode as part of the early_init process.

[PATCH v7 11/45] drm/amd: Load MES microcode during early_init

[Mario Limonciello]

Add an early_init phase to MES for fetching and validating microcode
from the filesystem.

If MES microcode is required but not available during early init, the
firmware framebuffer will have already been released and the screen will
freeze.

Move the request for MES microcode into the early_init phase
so that if it's not available, early_init will fail.

[PATCH v7 12/45] drm/amd: Use `amdgpu_ucode_*` helpers for MES

[Mario Limonciello]

The `amdgpu_ucode_request` helper will ensure that the return code for
missing firmware is -ENODEV so that early_init can fail.

The `amdgpu_ucode_release` helper provides symmetry for releasing firmware.

[PATCH v7 14/45] drm/amd: Use `amdgpu_ucode_*` helpers for GFX9

[Mario Limonciello]

The `amdgpu_ucode_request` helper will ensure that the return code for
missing firmware is -ENODEV so that early_init can fail.

The `amdgpu_ucode_release` helper will provide symmetry on unload.

[PATCH v7 17/45] drm/amd: Load GFX10 microcode during early_init

[Mario Limonciello]

Simplifies the code so that GFX10 will get the firmware
name from `amdgpu_ucode_ip_version_decode` and then use this filename
to load microcode as part of the early_init process.

Any failures will cause the driver to fail to probe before the firmware
framebuffer has been removed.

[PATCH v7 18/45] drm/amd: Use `amdgpu_ucode_*` helpers for GFX11

[Mario Limonciello]

The `amdgpu_ucode_request` helper will ensure that the return code for
missing firmware is -ENODEV so that early_init can fail.

The `amdgpu_ucode_release` helper will provide symmetery on unload.

[PATCH v7 19/45] drm/amd: Load GFX11 microcode during early_init

[Mario Limonciello]

If GFX11 microcode is required but not available during early init, the
firmware framebuffer will have already been released and the screen will
freeze.

Move the request for GFX11 microcode into the early_init phase
so that if it's not available, driver init will fail.

   PSP v10 which matches previous behavior.  If it should match for Cezanne
   and PSPv11 too we can undo this part of the check.
v5->v6:
 * Rebase on earlier patches

Simplifies the code so that all PSP versions will get the firmware
name from `amdgpu_ucode_ip_version_decode` and then use this filename
to load microcode as part of the early_init process.

Any failures will cause the driver to fail to probe before the firmware
framebuffer has been removed.

[PATCH v7 24/45] drm/amd/display: Load DMUB microcode during early_init

[Mario Limonciello]

If DMUB is required for an ASIC, ensure that the microcode is available
and validates during early_init.

Any failures will cause the driver to fail to probe before the firmware
framebuffer has been removed.

[PATCH v7 29/45] drm/amd: Use `amdgpu_ucode_*` helpers for GFX6

[Mario Limonciello]

The `amdgpu_ucode_request` helper will ensure that the return code for
missing firmware is -ENODEV so that early_init can fail.

The `amdgpu_ucode_release` helper is for symmetry on unloading.

[PATCH v7 40/45] drm/amd: Use `amdgpu_ucode_*` helpers for CGS

[Mario Limonciello]

The `amdgpu_ucode_request` helper will ensure that the return code for
missing firmware is -ENODEV so that early_init can fail.

The `amdgpu_ucode_release` helper is for symmetry on unloading.

I meant the below lines to come after this call. Even if it gets some 
value during parsing for other SOCs, force to 0.

if (!(adev->apu_flags & AMD_APU_IS_RENOIR))
