This patch fixes memory alloction(contiguous or not) and cache mapping types(cachable or not). For this, it converts each type from user request into dma attribute properly.

For user framebuffers it's easier to just inline the exynos_drm_framebuffer_init helper instead of trying to adjust it - most of the things that helper sets up need to be overwritten anyway again due to the multiple backing storage objects support exynos has, but does not use for the fbdev.

Changelog v3: just code cleanup. Changelog v2: fix argument to dma_mmap_attr function. - use pages instead of kvaddr because kvaddr is 0 with DMA_ATTR_NO_KERNEL_MAPPING. Changelog v1: When gem allocation is requested, kernel space mapping isn't needed. But if need, such as console framebuffer, the physical pages would be mapped with kernel space though vmap function.

Changelog v2: Added details of original patch in chromium kernel Changelog v1: When fimd is turned off, we disable the clocks which will stop the dma. Now if we remove the current framebuffer, we cannot disable the overlay but the current framebuffer will still be freed. When fimd resumes, the dma will continue from where it left off and will throw a PAGE FAULT since the memory was freed. This patch fixes the above problem by disabling the fimd windows before disabling the fimd clocks. It also keeps track of which windows were currently active by setting the 'resume' flag. When fimd resumes, the window with a resume flag set is enabled again. Now if a current fb is removed when fimd is off, fimd_win_disable will set the 'resume' flag of that window to zero and return. So when fimd resumes, that window will not be resumed. This patch is based on the following two patches: http://git.chromium.org/gitweb/?p=chromiumos/third_party/kernel.git;a=commitdiff;h=341e973c967304976a762211b6465b0074de62ef http://git.chromium.org/gitweb/?p=chromiumos/third_party/kernel.git;a=commitdiff;h=cfa22e49b7408547c73532c4bb03de47cc034a05 These two patches are rebased onto the current kernel with additional changes like removing 'fimd_win_commit' call from the resume function since this is taken care by encoder dpms, and the modification of resume flag in win_disable.

It is more optimium to use wait queues while waiting for vsync so that the current task is put to sleep. This way, the task wont hog the CPU while waiting. We use wait_event_timeout and not an interruptible function since we dont want the function to exit when a signal is pending (e.g. drm release). This patch modifies the wait for vblank function of fimd. Signed-off-by: NPrathyush K <prathyush.k@samsung.com> Signed-off-by: NInki Dae <inki.dae@samsung.com>

With this patch, When dma_buf_unmap_attachment is called, the pages of sgt aren't unmapped from iommu table. Instead, when dma_buf_detach is called, that would be done. And also removes exynos_get_sgt function used to get clone sgt and uses attachment's sgt instead. This patch would resolve performance deterioration issue when v4l2-based driver is using the buffer imported from gem.

All items on the lru list are always reservable, so this is a stupid thing to keep. Not only that, it is used in a way which would guarantee deadlocks if it were ever to be set to block on reserve. This is a lot of churn, but mostly because of the removal of the argument which can be nested arbitrarily deeply in many places. No change of code in this patch except removal of the no_wait_reserve argument, the previous patch removed the use of no_wait_reserve. v2: - Warn if -EBUSY is returned on reservation, all objects on the list should be reservable. Adjusted patch slightly due to conflicts. v3: - Focus on no_wait_reserve removal only.
