2015-08-06drm/fb_helper: Create wrappers for blit, copyarea and fillrect funcsArchit Taneja
drm drivers that emulate fbdev populate their fb_fillrect, fb_copyarea and fb_imageblit fb_ops with the help of cfb_* or sys_* fbdev core helper functions. Create drm_fb_helper functions that wrap around these calls. This is part of an effort to prevent drm drivers from calling fbdev functions directly, in order to make fbdev emulation a top level drm option. v3: - Fixed kerneldoc errors v2: - Added kerneldocs - Follow the drm way of aligning of arguments in func definitions - Remove unnecessary checks for non NULL fb_info Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

Some drm drivers call unlink_framebuffer. Create a drm_fb_helper function that wraps around these calls. This is part of an effort to prevent drm drivers from calling fbdev functions directly, in order to make fbdev emulation a top level drm option. v2: - Added kerneldocs - Added a check for non-NULL fb_helper before proceeding.

2015-08-06drm/fb_helper: Add drm_fb_helper functions to manage fb_info creationArchit Taneja
Every drm driver calls framebuffer_alloc, fb_alloc_cmap, unregister_framebuffer, fb_dealloc_cmap and framebuffer_release in order to emulate fbdev support. Create drm_fb_helper functions that perform the above operations. This is part of an effort to prevent drm drivers from calling fbdev functions directly. It also removes repetitive code from drivers. There are some drivers that call alloc_apertures after framebuffer_alloc and some that don't. Make the helper always call alloc_apertures. This would make certain drivers allocate memory for apertures but not use them. Since it's a small amount of memory, it shouldn't be an issue. v2: - Added kerneldocs - Added a check for non-NULL fb_helper before proceeding. This will make the helpers work when we have a module param for fbdev emulation Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

It is true that in a product we won't keep disabling and enabling planes so frequently, but for safeness let's stay conservative. It is also true that 500ms is an etternity. But PSR is anyway a power saving feature for idle scenario. So if it is idle feature stays on and 500ms to get it reanabled is not that insane. v2: Rebase over intel_psr.c and fix typo. v3: Revival: Manual tests indicated that this is needed.

2015-08-05drm/i915: special-case dirtyfb for frontbuffer trackingPaulo Zanoni
First, an introduction. We currently have two types of GTT mmaps: the "normal" old mmap, and the WC mmap. For frontbuffer-related features that have automatic hardware tracking, only the non-WC mmap writes are detected by the hardware. Since inside the Kernel both are treated as ORIGIN_GTT, any features ignoring ORIGIN_GTT because of the hardware tracking are destined to fail. One of the special rules defined for the WC mmaps is that the user should call the dirtyfb IOCTL after he is done using the pointers, so that results in an intel_fb_obj_flush() call. The problem is that the dirtyfb is passing ORIGIN_GTT, so it is being ignored by FBC - even though the hardware tracking is not detecing the WC mmap operations. So in order to fix that without having to give up the automatic hardware tracking for GTT mmaps we transform the flush operation from dirtyfb into a special operation: ORIGIN_DIRTYFB. This commit fixes all the kms_frontbuffer_tracking subtests that contain "fbc" and "mmap-wc" in their names and are currently failing (for a total of 16 subtests).

2015-08-05drm/i915: don't disable FBC for pipe A when flipping pipe BPaulo Zanoni
Use the appropriate call. I know there's a discussion about whether we need this call here at all, but removing the call means we'll only update FBC after we get the page flip IRQ. So the user may only see the new frame a little after it should. Let's wait just a little bit more before removing this call since we can rely in the HW tracking for accurate flips.

2015-08-05drm/i915: don't call intel_fbc_update() at intel_unpin_work_fn()Paulo Zanoni
Because intel_unpin_work_fn() already calls intel_frontbuffer_flip_complete() which will call intel_fbc_flush() which will call intel_fbc_update() when needed. We couldn't fix this previously due to the fact that FBC was not properly behaving as intended on frontbuffer flushes, but now that this is fixed, we can remove the additional call.

2015-08-05drm/i915: fix FBC frontbuffer tracking flushing codePaulo Zanoni
Due to the way busy_bits was handled, we were not doing any flushes if we didn't previously get an invalidate. Since it's possible to get flushes without an invalidate first, remove the busy_bits early return. So now that we don't have the busy_bits guard anymore we'll need the origin check for the GTT tracking (we were not doing anything on GTT flushes due to the GTT check at invalidate()). As a last detail, since we can get multiple consecutive flushes, disable FBC before updating it, otherwise intel_fbc_update() will just keep FBC enabled instead of restarting it. Notice that this does not fix any of the current IGT tests due to the fact that we still have a few intel_fbc() calls at points where we also have the frontbuffer tracking calls: we didn't fully convert to frontbuffer tracking yet. Once we remove those calls and start relying only on the frontbuffer tracking infrastructure we'll need this patch.
