drm/ast: Fixed reboot test may cause system hanged

2019-09-06T08:23:26+00:00

[ Upstream commit 05b439711f6ff8700e8660f97a1179650778b9cb ] There is another thread still access standard VGA I/O while loading drm driver. Disable standard VGA I/O decode to avoid this issue.

drm/ttm: Quick-test mmap offset in ttm_bo_mmap()

2019-03-19T20:03:53+00:00

A BO's address has to be at least the minimum offset. Sharing this test in ttm_bo_mmap() removes code from drivers. A full buffer-address validation is still done within drm_vma_offset_lockup_locked().

drm/ttm: Remove file_page_offset parameter from ttm_bo_device_init()

The parameter file_page_offset is a constant shared by all drivers. Just replace it with the constant itself. Signed-off-by: Thomas Zimmermann Reviewed-by: Christian König Acked-by: Hans de Goede Signed-off-by: Alex Deucher

drm/ttm: Define a single DRM_FILE_PAGE_OFFSET constant

2019-03-19T20:03:53+00:00

Most TTM drivers define the constant DRM_FILE_PAGE_OFFSET of the same value. The only exception is vboxvideo, which is being converted to the new offset by this patch. Unifying the constants in a single place simplifies the driver code. Signed-off-by: Thomas Zimmermann Reviewed-by: Christian König Acked-by: Hans de Goede Signed-off-by: Alex Deucher

drm/ast: Replace ttm_bo_unref with ttm_bo_put

2019-01-28T16:42:41+00:00

The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer.

drm: Split out drm_probe_helper.h

2019-01-24T12:20:42+00:00

Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.
