drm/amd/display: check for ipp before calling cursor operations

2018-02-28T20:14:41+00:00

Currently all cursor related functions are made to all
pipes that are attached to a particular stream.
This is not applicable to pipes that do not have cursor plane
initialised like underlay.
Hence this patch allows cursor related operations on a pipe
only if ipp in available on that particular pipe.

The check is added to set_cursor_position & set_cursor_attribute.

treewide/trivial: Remove ';;$' typo noise

2018-02-22T09:59:33+00:00

On lkml suggestions were made to split up such trivial typo fixes into per subsystem
patches:

  --- a/arch/x86/boot/compressed/eboot.c
  +++ b/arch/x86/boot/compressed/eboot.c
  @@ -439,7 +439,7 @@ setup_uga32(void **uga_handle, unsigned long size, u32 *width, u32 *height)

This patch is the result of the following script:

  $ sed -i 's/;;$/;/g' $(git grep -E ';;$'  | grep "\.[ch]:"  | grep -vwE 'for|ia64' | cut -d: -f1 | sort | uniq)

... followed by manual review to make sure it's all good.

Splitting this up is just crazy talk, let's get over with this and just do it.

drm/amdgpu: Unify the dm resume calls into one

2018-02-20T20:09:54+00:00

amdgpu_dm_display_resume is now called from dm_resume to
unify DAL resume call into a single function call

There is no more need to separately call 2 resume functions
for DM.

Initially they were separated to resume display state after
cursor is pinned. But because there is no longer any corruption
with the cursor - the calls can be merged into one function hook.

drm/amd/display: Demote error print to debug print when ATOM impl missing

2018-01-24T20:47:25+00:00

I assumed wrongfully that all relevant functions should be implemented.
Apparently this isn't the case. Demote the print to debug level for now.
