Hi Inki,
how urgent is this? Linus isn't really up for something this large post -rc7, major regressions or oops fixes only at this point.
If its not urgent can we just stick it in -next and if needs be you can get stable on required patches.
Dave.
Please pull from git://git.infradead.org/users/kmpark/linux-samsung exynos-drm-fixes
these patch sets are based on git repository below: git://people.freedesktop.org/~airlied/linux.git drm-fixes commit-id: a3928c6b5f43bcd561802b52049b6024b8da675f
this pull requst includes previous one and new two patches posted last week for review. so please ignore previous request and pull this one. for previous request, you can refer to below link: http://comments.gmane.org/gmane.comp.video.dri.devel/71136
this patch set includes the following:
- change exynos gem allocation interface. . this patch makes non-contiguous memory allocation request allocate pages from highmem through alloc_page() with GFP_HIGHUSER_MOVABLE because cpu may read garbage data from cache once gpu operation is completed with allocated pages. shmem_read_mapping_page_gfp() first tries to allocate pages from page cache so if pages are alloated from page cache then these pages could have valid line and we had faced with this issue.
- check if framebuffer and gem size are valid or not. . with addfb or addfb2 request by user, invalid framebuffer or gem size could be sent into kernel side so this could induce invalid memory access by dma of a device. so this patch checks if framebuffer and gem size are valid or not.
- add exception codes to vidi module. . edid data from user should be allocatd and copied into vidi context and also freed with disconnection.
- and code clean.
please let me know it there is any problem. Thanks.
