2014-11-16drm/msm: small mmap offset cleanupsRob Clark1-3/+1
Use pre-computed iova when unmapping, to reduce the places we assume iova and mmap offset are (at the moment) the same. And get rid of an extra drm_gem_free_mmap_offset() call (since it is already called from drm_gem_object_release()) Signed-off-by: Rob Clark <robdclark@gmail.com>

2014-11-16drm/msm: Fix fbdev for 16- and 24-bit modes.Daniel Thompson1-3/+0
Currently forcing the video mode from the kernel command line (for example video=HDMI-A-1:1280x720-16@60) does not correctly set the number of bits per pixel. This is due to a rather aggressive override in msm_fbdev_create(). This is a particular problem for Android bring up because the software EGL fallbacks don't support 32bpp. Since the overrides are actually the default values anyway then this problem can be trivially fixed by removing the overrides completely. Change was tested by dd'ing a test image to /dev/fb0 with no video= (still 32bpp), video=1920x1080-32@60, video=1920x1080-24@60 and video=1920x1080-16@60 .

git://people.freedesktop.org/~tagr/linux into drm-next drm: Sanitize DRM_IOCTL_MODE_CREATE_DUMB input Some drivers erroneously treat the .pitch and .size fields of struct drm_mode_create_dumb as inputs. While the include/uapi/drm/drm_mode.h header has a comment denoting them as outputs, that seemingly wasn't enough to make drivers use them properly. The result is that some userspace doesn't explicitly zero out those fields, assuming that the kernel won't use them. That causes problems since the data within the structure might be uninitialized, so bogus data may end up confusing drivers (ridiculously large values for the pitch, ...). This series attempts to improve the situation by fixing all drivers to not use the output fields. Furthermore to spare new drivers this bad surprise, the DRM core now zeros out these fields prior to handing the data structure to the driver. Lessons learned from this are that future IOCTLs should be properly documented (in the DRM DocBook for example) and should be rigorously defined. To prevent misuse like this, userspace should be required to zero out all output fields. The kernel should check for this and fail if that's not the case. * tag 'drm/gem-cma/for-3.19-rc1' of git://people.freedesktop.org/~tagr/linux: drm/cma: Remove call to drm_gem_free_mmap_offset() drm: Sanitize DRM_IOCTL_MODE_CREATE_DUMB input drm/rcar: gem: dumb: pitch is an output drm/omap: gem: dumb: pitch is an output drm/cma: Introduce drm_gem_cma_dumb_create_internal() drm/doc: Add GEM/CMA helpers to kerneldoc drm/doc: mm: Fix indentation drm/gem: Fix a few kerneldoc typos

git://people.freedesktop.org/~tagr/linux into drm-next drm/tegra: Changes for v3.19-rc1 The highlights in this pull request are: * IOMMU support: The Tegra DRM driver can now deal with discontiguous buffers if an IOMMU exists in the system. That means it can allocate using drm_gem_get_pages() and will map them into IOVA space via the IOMMU API. Similarly, non-contiguous PRIME buffers can be imported from a different driver, which allows better integration with gk20a (nouveau) and less hacks. * Universal planes: This is precursory work for atomic modesetting and will allow hardware cursor support to be implemented on pre-Tegra114 where RGB cursors were not supported. * DSI ganged-mode support: The DSI controller can now gang up with a second DSI controller to drive high resolution DSI panels. Besides those bigger changes there is a slew of fixes, cleanups, plugged memory leaks and so on. * tag 'drm/tegra/for-3.19-rc1' of git://people.freedesktop.org/~tagr/linux: (44 commits) drm/tegra: gem: Check before freeing CMA memory drm/tegra: fb: Add error codes to error messages drm/tegra: fb: Properly release GEM objects on failure drm/tegra: Detach panel when a connector is removed drm/tegra: Plug memory leak drm/tegra: gem: Use more consistent data types drm/tegra: fb: Do not destroy framebuffer drm/tegra: gem: dumb: pitch and size are outputs drm/tegra: Enable the hotplug interrupt only when necessary drm/tegra: dc: Universal plane support drm/tegra: dc: Registers are 32 bits wide drm/tegra: dc: Factor out DC, window and cursor commit drm/tegra: Add IOMMU support drm/tegra: Fix error handling cleanup drm/tegra: gem: Use dma_mmap_writecombine() drm/tegra: gem: Remove redundant drm_gem_free_mmap_offset() drm/tegra: gem: Cleanup tegra_bo_create_with_handle() drm/tegra: gem: Extract tegra_bo_alloc_object() drm/tegra: dsi: Set up PHY_TIMING & BTA_TIMING registers earlier drm/tegra: dsi: Replace 1000000 by USEC_PER_SEC ...
