2015-08-05drm/vmwgfx: Implement fbdev on kms v2Thomas Hellstrom
With screen targets the old legacy display system fbdev doesn't work satisfactory anymore. At best the resolution is severely restricted. Therefore implement fbdev on top of the kms system. With this change, fbdev will be using whatever KMS backend is chosen. There are helpers available for this, so in the future we'd probably want to implement the helper callbacks instead of calling into our KMS implementation directly. v2: Make sure we take the mode_config mutex around modesetting, Also clear the initial framebuffer using vzalloc instead of vmalloc.

2015-08-05drm/vmwgfx: Add a kernel interface to create a framebuffer v2Thomas Hellstrom
The kernel interface is needed for fbdev, and needs to be free from a file_priv member. To accomplish this, remove the fb surface mutex and list which isn't used anymore, anyway. Finally, make the pin() and unpin() pin the framebuffer for all display system backends, so that fbdev can pin its framebuffer before mapping it. v2: Address review comments: - Fix vmw_framebuffer_unpin() to handle also the surface framebuffer case. - Fix vmw_kms_new_framebuffer() to actually use the only_2d parameter.

2015-08-05drm/vmwgfx: Avoid cmdbuf alloc sleeping if !TASK_RUNNINGThomas Hellstrom
If the command buffer pool is out of space, the code waits until space is available. However since the condition code tries to allocate a range manager node while !TASK_RUNNING we get a kernel warning. Avoid this by pre-allocating the mm node. This will also probably be more efficient. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Sinclair Yeh <syeh@vmware.com>

2015-08-05drm/vmwgfx: Replace SurfaceDMA usage with SurfaceCopy in 2D VMsSinclair Yeh
This patch address the following underlying issues with SurfaceDMA * SurfaceDMA command does not work in a 2D VM, but we can wrap a proxy surface around the same DMA buffer and use the SurfaceCopy command which does work in a 2D VM. * Wrapping a DMA buffer with a proxy surface also gives us an added optimization path for the case when the DMA buf dimensions match the mode. In this case, the DMA buf can be pinned as the display surface, saving an extra copy. This only works in a 2D VM because we won't be doing any rendering operations directly to the display surface. v2 * Moved is_dmabuf_proxy field to vmw_framebuffer_surface * Undone coding style changes * Addressed other issues from review Signed-off-by: Sinclair Yeh <syeh@vmware.com> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com>

2015-08-05drm/i915: VLV/CHV PSR: Increase wait delay time before active PSR.Rodrigo Vivi

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. With a short delay there is a huge risk of getting blank screens when planes are being enabled. v4: Revival 2 with reasonable delay. 1/2 sec instead of 5. VBT is 10 sec but actually time for link training what we aren't doing, but with only 100 sec in some cases kms_psr_sink_crc manual was showing blank screen, so let's use this for now. Also changed comment by a FIXME. v5: Rebase after a long time, remove FIXME and update comment above. v6: msecs_to_jiffies is already on delay. remove duplication. v7: use msecs_to_jiffies on schedule_delayed_work call.

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: 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.

Fix this functional bug by implemented a correct atomic-state based encoder selector for dp mst. Note that we can't get rid of the legacy best_encoder callback since the fbdev emulation uses that still. That means it's incorrect there still, but that's been the case ever since i915 dp mst support was merged so not a regression. Best to fix that by converting fbdev over to atomic too.

2015-08-02i915: temporary fix for DP MST docking station NULL pointer dereferenceLinus Torvalds
Ted Ts'o reports that his Lenovo T540p ThinkPad crashes at boot if attached to the docking station. This is a regression that he was able to bisect to commit 8c7b5ccb7298: "drm/i915: Use atomic helpers for computing changed flags:" The reason seems to be the new call to drm_atomic_helper_check_modeset() added to intel_modeset_compute_config(), which in turn calls update_connector_routing(), and somehow ends up picking a NULL crtc for the connector state, causing the subsequent drm_crtc_index() to OOPS. Daniel Vetter says that the fundamental issue seems to be confusion in the encoder selection, and this isn't the right fix, but while he chases down the proper fix, this at least avoids the NULL pointer dereference and makes Ted's docking station work again.

2015-07-30drm/i915: Declare the swizzling unknown for L-shaped configurationsChris Wilson
The old style of memory interleaving swizzled upto the end of the first even bank of memory, and then used the remainder as unswizzled on the unpaired bank - i.e. swizzling is not constant for all memory. This causes problems when we try to migrate memory and so the kernel prevents migration at all when we detect L-shaped inconsistent swizzling. However, this issue also extends to userspace who try to manually detile into memory as the swizzling for an individual page is unknown (it depends on its physical address only known to the kernel), userspace cannot correctly swizzle. Note that this is a new attempt for the previously merged one, reverted in commit d82c0ba6e306f079407f07003e53c262d683397b Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Jul 14 12:29:27 2015 +0200 Revert "drm/i915: Declare the swizzling unknown for L-shaped configurations" This is cc: stable since we need it to fix up troubles with wc cpu mmaps that userspace recently started to use widely.

2015-07-30drm/i915: Mark PIN_USER binding as GLOBAL_BIND without the aliasing ppgttChris Wilson
If the device does not support the aliasing ppgtt, we must translate user bind requests (PIN_USER) from LOCAL_BIND to a GLOBAL_BIND. However, since this is device specific we cannot do this conveniently in the upper layers and so must manage the vma->bound flags in the backend.
