Subject: [PATCH] drm/radeon: fix UVD suspend error
Date: Mon, 17 Jan 2022 15:47:31 +0800	[thread overview]
Message-ID: <20220117074731.29882-1-maqianga@uniontech.com> (raw)

I met a bug recently and the kernel log:

[  330.171875] radeon 0000:03:00.0: couldn't schedule ib
[  330.175781] [drm:radeon_uvd_suspend [radeon]] *ERROR* Error destroying UVD (-22)!

In radeon drivers, using UVD suspend is as follows:

if (rdev->has_uvd) {
        uvd_v1_0_fini(rdev);
        radeon_uvd_suspend(rdev);
}

In radeon_ib_schedule function, we check the 'ring->ready' state,
but in uvd_v1_0_fini funciton, we've cleared the ready state.
So, just modify the suspend code flow to fix error.
