... thanks for you reply. Yes, that was the idea and would be very nice...
Since i thing the proposed fix is more relevant to this very thread, let me
repeat the proposed patch here:
in 'drivers/gpu/drm/amd/powerplay/hwmgr/vega10_hwmgr.c':
static void vega10_notify_smc_display_change(struct pp_hwmgr *hwmgr,
bool has_disp)
{
smum_send_msg_to_smc_with_parameter(hwmgr,
PPSMC_MSG_SetUclkFastSwitch,
has_disp ? 1 : 0);
/* proposed fix for crashes because of frequently mclk level 0/1 switching */
smum_send_msg_to_smc_with_parameter(hwmgr, PPSMC_MSG_SetUclkDownHyst,
1);
}
Only module 'amdgpu.ko' needs to be rebuild and copied, like this:
$ cd /home/user/linux-5.x.x && make -j8 -C . M=drivers/gpu/drm/amd/amdgpu
# cp /home/user/linux-5.x.x/drivers/gpu/drm/amd/amdgpu/amdgpu.ko
/lib/modules/5.x.x/kernel/drivers/gpu/drm/amd/amdgpu/amdgpu.ko &&
update-initramfs -u
... 'user' and 'x.x' have to be adapted, most likely ...
