drm/amdgpu: fix GFXOFF on Picasso and Raven2

2019-08-27T17:25:20Z

For picasso(adev->pdev->device == 0x15d8)&raven2(adev->rev_id >= 0x8), firmware is sufficient to support gfxoff. In commit 98f58ada2d37e, for picasso&raven2, return directly and cause gfxoff disabled.

drm/amdgpu: prevent memory leaks in AMDGPU_CS ioctl

2019-08-21T22:32:39Z

Error out if the AMDGPU_CS ioctl is called with multiple SYNCOBJ_OUT and/or TIMELINE_SIGNAL chunks, since otherwise the last chunk wins while the allocated array as well as the reference counts of sync objects are leaked.

drm/amdgpu/gfx9: update pg_flags after determining if gfx off is possible

2019-08-21T22:29:49Z

We need to set certain power gating flags after we determine if the firmware version is sufficient to support gfxoff. Previously we set the pg flags in early init, but we later we might have disabled gfxoff if the firmware versions didn't support it. Move adding the additional pg flags after we determine whether or not to support gfxoff.

Revert "drm/amdgpu: fix transform feedback GDS hang on gfx10 (v2)"

2019-08-07T04:28:41Z

This reverts commit 9ed2c993d723129f85101e51b2ccc36ef5400a67. SET_CONFIG_REG writes to memory if register shadowing is enabled, causing a VM fault. NGG streamout is unstable anyway, so all UMDs should use legacy streamout. I think Mesa is the only driver using NGG streamout.

Without this pin, the csb buffer will be filled with inconsistent data after S3 resume. And that will causes gfx hang on gfxoff exit since this csb will be executed then. Signed-off-by: Likun Gao Tested-by: Paul Gover Reviewed-by: Feifei Xu Reviewed-by: Xiaojie Yuan Signed-off-by: Alex Deucher
