Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/amdgpu: fix gpu page fault after hibernation on PF passthrough<br />
<br />
On PF passthrough environment, after hibernate and then resume, coralgemm<br />
will cause gpu page fault.<br />
<br />
Mode1 reset happens during hibernate, but partition mode is not restored<br />
on resume, register mmCP_HYP_XCP_CTL and mmCP_PSP_XCP_CTL is not right<br />
after resume. When CP access the MQD BO, wrong stride size is used,<br />
this will cause out of bound access on the MQD BO, resulting page fault.<br />
<br />
The fix is to ensure gfx_v9_4_3_switch_compute_partition() is called<br />
when resume from a hibernation.<br />
KFD resume is called separately during a reset recovery or resume from<br />
suspend sequence. Hence it&#39;s not required to be called as part of<br />
partition switch.<br />
<br />
