* drm/i915: don't bail out of intel_wait_ring_buffer too earlyDaniel Vetter2012-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the pre-gem days with non-existing hangcheck and gpu reset code, this timeout of 3 seconds was pretty important to avoid stuck processes. But now we have the hangcheck code in gem that goes to great length to ensure that the gpu is really dead before declaring it wedged. So there's no need for this timeout anymore. Actually it's even harmful because we can bail out too early (e.g. with xscreensaver slip) when running giant batchbuffers. And our code isn't robust enough to properly unroll any state-changes, we pretty much rely on the gpu reset code cleaning up the mess (like cache tracking, fencing state, active list/request tracking, ...). With this change intel_begin_ring can only fail when the gpu is wedged, and it will return -EAGAIN (like wait_request in case the gpu reset is still outstanding). v2: Chris Wilson noted that on resume timers aren't running and hence we won't ever get kicked out of this loop by the hangcheck code. Use an insanely large timeout instead for the HAS_GEM case to prevent resume bugs from totally hanging the machine.

* drm/i915: kicking rings stuck on semaphores considered harmfulDaniel Vetter2012-01-03
| | | | | | | | | | | | | | | | | | If our semaphore logic gets confused and we have a ring stuck waiting for one, there's a decent chance it'll just execute garbage when being kicked. Also, kicking the ring obscures the place where the error first occured, making error_state decoding much harder. So drop this an let gpu reset handle this mess in a clean fashion. In contrast, kicking rings stuck on MI_WAIT is rather harmless, at worst there'll be a bit of screen-flickering. There's also old broken userspace out there which needs this as a work-around.

* drm/i915: Add support for resetting the SO write pointers on gen7.Eric Anholt2012-01-03
| | | | | | | | | | | | | | | | | | | | | These registers are automatically incremented by the hardware during transform feedback to track where the next streamed vertex output should go. Unlike the previous generation, which had a packet for setting the corresponding registers to a defined value, gen7 only has MI_LOAD_REGISTER_IMM to do so. That's a secure packet (since it loads an arbitrary register), so we need to do it from the kernel, and it needs to be settable atomically with the batchbuffer execution so that two clients doing transform feedback don't stomp on each others' state. Instead of building a more complicated interface involcing setting the registers to a specific value, just set them to 0 when asked and userland can tweak its pointers accordingly.

| | | | | | | | | | | | | | | | | | | | Previous to this commit, testing easily reproduced a failure where the seqno would apparently arrive after the IRQ associated with it, with test programs as simple as: for (;;) { glCopyPixels(0, 0, 1, 1); glFinish(); } Various workarounds we've seen for previous generations didn't work to fix this issue, so until new information comes in, replace the IRQ waits on the BLT ring with polling.

* drm/i915: Clean up multi-threaded forcewake patchKeith Packard2012-01-03
| | | | | | | | | | | | | | | | | | We learned that the ECOBUS register was inside the GT power well, and so *did* need force wake to be read, so it gets removed from the list of 'doesn't need force wake' registers. That means the code reading ECOBUS after forcing the mt_force_wake function to be called needs to use I915_READ_NOTRACE; it doesn't need to do more force wake fun as it's already done it manually. This also adds a comment explaining why the MT forcewake testing code only needs to call mt_forcewake_get/put and not disable RC6 manually -- the ECOBUS read will return 0 if the device is in RC6 and isn't using MT forcewake, causing the test to work correctly.

| | | | | | | | | | | | | | | Many of the old fields from Ironlake have gone away. Strip all those fields, and try to update to fields people care about. RC information isn't exactly ideal anymore. All we can guarantee when we read the register is that we're not using forcewake, ie. the software isn't forcing the hardware to stay awake. The downside is that in doing this we may wait a while and that causes an unnaturally idle state on the GPU.

* drm/i915: relative_constants_mode race fixBen Widawsky2012-01-03
| | | | | | | | | | | | | | | | | | | dev_priv keeps track of the current addressing mode that gets set at execbuffer time. Unfortunately the existing code was doing this before acquiring struct_mutex which leaves a race with another thread also doing an execbuffer. If that wasn't bad enough, relocate_slow drops struct_mutex which opens a much more likely error where another thread comes in and modifies the state while relocate_slow is being slow. The solution here is to just defer setting this state until we absolutely need it, and we know we'll have struct_mutex for the remainder of our code path. v2: Keith noticed a bug in the original patch.

Contrary to a similar patch by Ben Widawsky this does not check INSTDONE of the other rings. Chris Wilson implied that in a failure to detect a hang, most likely because INSTDONE was fluctuating. Thus only check ACTHD, which as far as I know is rather reliable. Also, blitter and bsd rings can't launch complex tasks from a single instruction (like 3D_PRIM on the render with complex or even infinite shaders). This fixes spurious gpu hang detection when running tests/gem_hangcheck_forcewake on snb/ivb.

There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv and some low level code is already in s5p-tv and even headers for register define are almost same. but in this patch, we decide not to consider separated common code with s5p-tv. Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc. 1. mixer. The piece of hardware responsible for mixing and blending multiple data inputs before passing it to an output device. The mixer is capable of handling up to three image layers. One is the output of VP. Other two are images in RGB format. The blending factor, and layers' priority are controlled by mixer's registers. The output is passed to HDMI. 2. vp (video processor). It is used for processing of NV12/NV21 data. An image stored in RAM is accessed by DMA. The output in YCbCr444 format is send to mixer. 3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes pixel data from mixer and transforms it into data frames. The output is send to HDMIPHY interface. 4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to HDMI connector. Basically, it contains a PLL that produces source clock for mixer, vp and hdmi. 5. ddc (display data channel). It is dedicated i2c channel to exchange display information as edid with display monitor. With plane support, exynos hdmi driver fully supports two mixer layes and vp layer. Also vp layer supports multi buffer plane pixel formats having non contigus memory spaces. In exynos drm driver, common drm_hdmi driver to interface with drm framework has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls them. mixer controls all overlay layers in both mixer and vp. Vblank interrupts for hdmi are handled by mixer internally because drm framework cannot support multiple irq id. And pipe number is used to check which display device irq happens.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i810 uses a userspace provided mmio map using the drm core map infrastructure. By the time we reach lastclose, this is all gone and our mmio_map pointer points at freed memory. Depending upon luck that still works, most often it just oopses. Aside: drm maps aren't refcounted, so userspace can essentially oops the kernel any time it wants to. Who cares. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My dear old i815 always hits the deadlocked on reclaim_buffers warning. Switch over to the idlelock duct-tape on hope that works better. I've fired up my i815 and now closing glxgears doesn't take 5 seconds anymore. \o/ Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To make the transition in a piece-wise and bisectable way possible, I've hijacked the ->owner_list from drm_sman. While transitioning, the list_add was done by the driver, while the list_del was still done by the dying sman code. Now that we are in full control of ->owner_list, do the list_del ourselves. v2: Better explain the list_del trickery as suggested by Chris Wilson.
