From: Michel Dänzer <michel.daenzer@xxxxxxx> We were clobbering entries in mi's global miSpritePointerFuncs struct, which cannot work correctly with multiple primary screens. Instead, assign a pointer to our own wrapper struct to PointPriv->spriteFuncs. Fixes crashes with multiple primary screens. Fixes: 69e20839bfeb ("Keep track of how many SW cursors are visible on each screen") Reported-by: Mario Kleiner <mario.kleiner.de at gmail.com> Signed-off-by: Michel Dänzer <michel.daenzer at amd.com> --- src/amdgpu_drv.h | 4 +--- src/amdgpu_kms.c | 14 ++++-------- src/drmmode_display.c | 61 ++++++++++++++++++++++++++++++++++++++++++++++----- src/drmmode_display.h | 7 +++--- 4 files changed, 63 insertions(+), 23 deletions(-) diff --git a/src/amdgpu_drv.h b/src/amdgpu_drv.h index 40157262e..acf697730 100644 --- a/src/amdgpu_drv.h +++ b/src/amdgpu_drv.h @@ -281,9 +281,7 @@ typedef struct { CreateScreenResourcesProcPtr CreateScreenResources;
