drm/amd/amdgpu: Correct ring wptr address in debugfs (v2)

2017-03-30T03:55:53+00:00

On gfx9 hardware the value is not wrapped and is a 64-bit value. So we reduce it modulo the ring size. Signed-off-by: Tom St Denis Reviewed-by: Christian König (v2) use buf_mask instead of computing on the fly Signed-off-by: Alex Deucher

drm/amdgpu:fix ring init sequence

2017-03-30T03:55:38+00:00

ring->buf_mask need be set prior to ring_clear_ring invoke and fix ring_clear_ring as well which should use buf_mask instead of ptr_mask Signed-off-by: Monk Liu Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: add 64bit wb functions

2017-03-30T03:53:35+00:00

Newer asics need 64 bit writeback slots. Reviewed-by: Christian König Signed-off-by: Ken Wang Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: change wptr to 64 bits (v2)

2017-03-30T03:53:35+00:00

Newer asics need 64 bit wptrs. If the wptr is now smaller than the rptr that doesn't indicate a wrap-around anymore. v2: integrate Christian's comments. Signed-off-by: Ken Wang Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu:use clear_ring to clr RB

2017-03-30T03:53:14+00:00

In resume routine, we need clr RB prior to the ring test of engine, otherwise some engine hang duplicated during GPU reset. Signed-off-by: Monk Liu Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu:set cond_exec polling value to 1 in ring_init

2017-01-27T16:13:37+00:00

no need to set it per ib_schedule(), hw won't override this polling address. Signed-off-by: Monk Liu Reviewed-by: Christian König Signed-off-by: Alex Deucher

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

2016-12-16T18:24:44+00:00

Pull vfs updates from Al Viro: - more ->d_init() stuff (work.dcache) - pathname resolution cleanups (work.namei) - a few missing iov_iter primitives - copy_from_iter_full() and friends. Either copy the full requested amount, advance the iterator and return true, or fail, return false and do _not_ advance the iterator. Quite a few open-coded callers converted (and became more readable and harder to fuck up that way) (work.iov_iter) - several assorted patches, the big one being logfs removal * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: logfs: remove from tree vfs: fix put_compat_statfs64() does not handle errors namei: fold should_follow_link() with the step into not-followed link namei: pass both WALK_GET and WALK_MORE to should_follow_link() namei: invert WALK_PUT logics namei: shift interpretation of LOOKUP_FOLLOW inside should_follow_link() namei: saner calling conventions for mountpoint_last() namei.c: get rid of user_path_parent() switch getfrag callbacks to ..._full() primitives make skb_add_data,{_nocache}() and skb_copy_to_page_nocache() advance only on success [iov_iter] new primitives - copy_from_iter_full() and friends don't open-code file_inode() ceph: switch to use of ->d_init() ceph: unify dentry_operations instances lustre: switch to use of ->d_init()

drm/amdgpu: move align_mask and nop into ring funcs as well (v2)

2016-10-25T18:38:38+00:00

They are constant as well. v2: update uvd and vce phys ring structures as well Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: move the ring type into the funcs structure (v2)

2016-10-25T18:38:37+00:00

It's constant, so it doesn't make to much sense to keep it with the variable data. v2: update vce and uvd phys mode ring structures as well Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher
