drm/amdgpu: fix xclk freq on CHIP_STONEY

2023-06-14T08:35:26+00:00

commit b447b079cf3a9971ea4d31301e673f49612ccc18 upstream.

According to Alex, most APUs from that time seem to have the same issue
(vbios says 48Mhz, actual is 100Mhz).  I only have a CHIP_STONEY so I
limit the fixup to CHIP_STONEY

drm/amdgpu: Fix PCI device refcount leak in amdgpu_atrm_get_bios()

2023-01-18T08:26:15+00:00

[ Upstream commit ca54639c7752edf1304d92ff4d0c049d4efc9ba0 ]

As comment of pci_get_class() says, it returns a pci_device with its
refcount increased and decreased the refcount for the input parameter
@from if it is not NULL.

If we break the loop in amdgpu_atrm_get_bios() with 'pdev' not NULL, we
need to call pci_dev_put() to decrease the refcount. Add the missing
pci_dev_put() to avoid refcount leak.

drm/amdgpu: Check BO's requested pinning domains against its preferred_domains

2022-08-25T09:11:12+00:00

commit f5ba14043621f4afdf3ad5f92ee2d8dbebbe4340 upstream.

When pinning a buffer, we should check to see if there are any
additional restrictions imposed by bo->preferred_domains. This will
prevent the BO from being moved to an invalid domain when pinning.

For example, this can happen if the user requests to create a BO in GTT
domain for display scanout. amdgpu_dm will allow pinning to either VRAM
or GTT domains, since DCN can scanout from either or. However, in
amdgpu_bo_pin_restricted(), pinning to VRAM is preferred if there is
adequate carveout. This can lead to pinning to VRAM despite the user
requesting GTT placement for the BO.

v2: Allow the kernel to override the domain, which can happen when
    exporting a BO to a V4L camera (for example).

drm/amd/pm: fix double free in si_parse_power_table()

2022-06-14T14:53:44+00:00

[ Upstream commit f3fa2becf2fc25b6ac7cf8d8b1a2e4a86b3b72bd ]

In function si_parse_power_table(), array adev->pm.dpm.ps and its member
is allocated. If the allocation of each member fails, the array itself
is freed and returned with an error code. However, the array is later
freed again in si_dpm_fini() function which is called when the function
returns an error.

This leads to potential double free of the array adev->pm.dpm.ps, as
well as leak of its array members, since the members are not freed in
the allocation function and the array is not nulled when freed.
In addition adev->pm.dpm.num_ps, which keeps track of the allocated
array member, is not updated until the member allocation is
successfully finished, this could also lead to either use after free,
or uninitialized variable access in si_dpm_fini().

Fix this by postponing the free of the array until si_dpm_fini() and
increment adev->pm.dpm.num_ps everytime the array member is allocated.
