2012-10-10Merge tag 'omapdss-for-3.7' of git://gitorious.org/linux-omap-dss2/linux ↵Florian Tobias Schandinat
into fbdev-next Omapdss driver changes for the 3.7 merge window. Notable changes: * Basic writeback support for DISPC level. Writeback is not yet usable, though, as we need higher level code to actually expose the writeback feature to userspace. * Rewriting the omapdss output drivers. We're trying to remove the hard links between the omapdss and the panels, and this rewrite work moves us closer to that goal. * Cleanup and restructuring patches that have been made while working on device tree support for omapdss. Device tree support is still some way ahead, but these patches are good cleanups in themselves. * Basic OMAP5 DSS support for DPI and DSI outputs. * Workaround for the problem that GFX overlay's fifo is too small for high resolution scenarios, causing underflows. * Cleanups that remove dependencies to omap platform code.
2012-10-09mm: kill vma flag VM_RESERVED and mm->reserved_vm counterKonstantin Khlebnikov
A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA, currently it lost original meaning but still has some effects: | effect | alternative flags -+------------------------+--------------------------------------------- 1| account as reserved_vm | VM_IO 2| skip in core dump | VM_IO, VM_DONTDUMP 3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP 4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP This patch removes reserved_vm counter from mm_struct. Seems like nobody cares about it, it does not exported into userspace directly, it only reduces total_vm showed in proc. Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP. remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP. remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

2012-10-04drm/i915: call drm_handle_vblank before finish_page_flipDaniel Vetter
... since finish_page_flip needs the vblank timestamp generated in drm_handle_vblank. Somehow all the gmch platforms get it right, but all the pch platform irq handlers get is wrong. Hooray for copy& pasting! Currently this gets papered over by a gross hack in finish_page_flip. A second patch will remove that. Note that without this, the new timestamp sanity checks in flip_test occasionally get tripped up, hence the cc: stable tag.

2012-10-04drm/exynos: update crtc to plane safelyInki Dae
if old_crtc isn't same as encoder->crtc then it means that user changed crtc id to another one so a plane to old_crtc should be disabled so that current plane can be updated safely and plane->crtc should be set to new crtc(encoder->crtc) Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
2012-10-04drm/exynos: check NV12M format specific to Exynos properlyInki Dae
this patch adds buf_cnt variable in exynos_drm_fb structure and that means a buffer count to drm framebuffer and also adds two functions to get/set the buffer count from/to exynos_drm_fb structure. if pixel format is not DRM_FORMAT_NV12MT then it gets a buffer count to drm framebuffer refering to mode_cmd->handles and offsets. but when booted, the buffer count will always be 1 because pixel format of console framebuffer is RGB format.

2012-10-04drm/exynos: make sure that hardware overlay for hdmi is disabledInki Dae
the values set to registers will be updated into real registers at vsync so dma operation could be malfunctioned when accessed to memory after gem buffer was released. this patch makes sure that hw overlay is disabled before the gem buffer is released.

Changelog v2: wait for VSYNC instead of BACKPORCH.

2012-10-04drm/exynos: add wait_for_vblank callback interface.Inki Dae
Changelog v2: fixed comments. Changelog v1: this interface can be used to make sure that hardware overlay is disabled to avoid that memory region is accessed by dma after gem buffer was released. Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
2012-10-04drm/exynos: fixed duplicated mode setting.Inki Dae
this patch fixes that when drm_crtc_helper_set_mode() is called, mode data for hardware overlay and conntroller are updated two times. for example, in case that drm_crtc_helper_set_mode() is called, overlay_ops->commit() and manager_ops->commit() callbacks can be called two times, first at drm_crtc_helper_set_mode() and second at drm_helper_connector_dpms().

2012-10-04drm/exynos: separated subdrv_probe function into two parts.Inki Dae
Changelog v2: fixed the issue that when sub driver is probed, no kms drivers such as fimd or hdmi are failed. no kms drivers have no manager so if manager is null then encoder and connector creation should be ignored. Changelog v1: this patch separates exynos_drm_subdrv_probe function into sub driver's probe call and encoder/connector creation so that exynos drm core module can take exception when some operation was failed properly.
