drm/msm/gpu: Fix crash when throttling GPU immediately during boot
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/gpu: Fix crash when throttling GPU immediately during boot
There is a small chance that the GPU is already hot during boot. In that
case, the call to of_devfreq_cooling_register() will immediately try to
apply devfreq cooling, as seen in the following crash:
Unable to handle kernel paging request at virtual address 0000000000014110
pc : a6xx_gpu_busy+0x1c/0x58 [msm]
lr : msm_devfreq_get_dev_status+0xbc/0x140 [msm]

a6xx_gpu_init+0x5c8/0x9c8 [msm]
adreno_bind+0x2a8/0x33c [msm]
...
At this point we haven't initialized the GMU at all yet, so we cannot read
the GMU registers inside a6xx_gpu_busy(). A similar issue was fixed before
in commit 6694482a70e9 ("drm/msm: Avoid unclocked GMU register access in
6xx gpu_busy"): msm_devfreq_init() does call devfreq_suspend_device(), but
unlike msm_devfreq_suspend(), it doesn't set the df->suspended flag
accordingly. This means the df->suspended flag does not match the actual
devfreq state after initialization and msm_devfreq_get_dev_status() will
end up accessing GMU registers, causing the crash.
Fix this by setting df->suspended correctly during initialization.
