We look at gem state (like obj->tiling/obj->stride), we better have the relevant locks. Right now this doesn't matter much since most of these checks are a curtesy to safe buggy userspace, but I'd like to freeze the tiling once we have framebuffer objects attached. And then locking matters. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

Parse the 3D_Structure_ALL and 3D_MASK fields of the HDMI Vendor Specific Data Block to expose more stereo 3D modes. v2: Use (1 << 0) for consistency. (Ville Syrjälä) Skip adding any modes if 3D_MASK is indicated as being present but the length only includes 3D_Structure_ALL. (Ville Syrjälä) Check that the value of HDMI_3D_LEN is large enough to include 3D_Structure_ALL and 3D_MASK, if they are present. (Ville Syrjälä) v3: Increment offset before the length checks.

This patch changes HDMI port registration order for the BayTrail platform. The story is that in kernel version 3.11 i915 supported only one HDMI port - the HDMIB port. So this port ended up being HDMI-1 in user-space. But commit '6f6005a5 drm/i915: expose HDMI connectors on port C on BYT' introduced HDMIC port support. And added HDMIC registration prior to HDMIB, so HDMIB became HDMI-2 and HDMIC became HDMI-1. Well, this is fine as far as the kernel is concerned. i915 does not give any guarantees to the numbering, and has never given them. However, this breaks wayland setup in Tizen IVI. We have only one single HDMI port on our hardware, and it is connected to HDMIB. Our configuration relies on the fact that it is HDMI-1. Well, certainly this is user-space problem which was exposed with Jesse's patch. However, there is a reason why we have to do this assumption - we use touchscreen monitors and we have to associate event devices with the monitors, and this is not easy to do dynamically, so we just have a static setup. Anyway, while the user-space setup will have to be fixed regardless, let's chane the HDMI port registration order so that HDMIB stays HDMI-1, just like it was in 3.11. Simply because there is no strong reason for changing the order in the kernel, and it'll help setups like ours in sense that we'll have more time for fixing the issue properly. Also amend the commentary which looks a bit out-of-date. Signed-off-by:

We have two once very similar functions, i915_gpu_idle() and i915_gem_idle(). The former is used as the lower level operation to flush work on the GPU, whereas the latter is the high level interface to flush the GEM bookkeeping in addition to flushing the GPU. As such i915_gem_idle() also clears out the request and activity lists and cancels the delayed work. This is what we need for unloading the driver, unfortunately we called i915_gpu_idle() instead. In the process, make sure that when cancelling the delayed work and timer, which is synchronous, that we do not hold any locks to prevent a deadlock if the work item is already waiting upon the mutex. This requires us to push the mutex down from the caller to i915_gem_idle(). v2: s/i915_gem_idle/i915_gem_suspend/ Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=70334Signed-off-by:

seq_file is not quite the right interface for these ones. We have a circular buffer with a new entry per vblank on one side and a process wanting to dequeue the CRC with a read(). It's quite racy to wait for vblank in user land and then try to read a pipe_crc file, sometimes the CRC interrupt hasn't been fired and we end up with an EOF. So, let's have the read on the pipe_crc file block until the interrupt gives us a new entry. At that point we can wake the reading process. Signed-off-by:

In the same spirit than: drm/i915: Generalize the CRC command format for future work Let's move from writing 'A plane1' to 'pipe A plane1' to i915_pipe_crc_ctl. This will allow us to extend the interface to transcoders or DDIs in the future. Let's rename the CRC control file to be more generic. Signed-off-by: -

I've sent this patch several times for various reasons. It essentially cleans up a lot of code where we need to do something per ring, and want to query whether or not the ring exists on that hardware. It has various uses coming up, but for now it shouldn't be too offensive. v2: Big conflict resolution on Damien's DEV_INFO_FOR_EACH stuff v3: Resolved vebox addition v4: Rebased after months of disuse. Also made failed ringbuffer init cleaner. v5: Remove the init cleaner from v4. There is a better way to do it. (Chris) Reviewed-by:

I had this lying around from he original PPGTT series, and thought we might try to get it in by itself. With the introduction of context refcounting we never explicitly ref/unref the backing object. As such, the previous fix was a bit wonky. Aside from fixing the above, this patch also puts us in good shape for an upcoming patch which allows a failure to occur in between context_init and the first do_switch.

I had this lying around from he original PPGTT series, and thought we might try to get it in by itself. It's convenient to just call i915_gem_init_hw at reset because we'll be adding new things to that function, and having just one function to call instead of reimplementing it in two places is nice. In order to accommodate we cleanup ringbuffers in order to bring them back up cleanly. Optionally, we could also teardown/re initialize the default context but this was causing some problems on reset which I wasn't able to fully debug, and is unnecessary with the previous context init/enable split.

Fill out the HSW watermark s/w tracking structures with the current hardware state in intel_modeset_setup_hw_state(). This allows us to skip the HW state readback during watermark programming and just use the values we keep around in dev_priv->wm.

Currently hsw_write_vm_values() may write to certain watermark registers needlessly. For instance if only, say, LP3 changes, the current code will again disable all LP1+ watermarks even though only LP3 needs to be reconfigured. Add an easy to read function that will compute the dirtyness of the watermarks, and use that information to further optimize the watermark programming. v2: Disable LP1+ watermarks around changing LP0 watermarks for Paulo Signed-off-by:

To make it easier to check what watermark updates are actually necessary, keep copies of the relevant bits that match the current hardware state. Also add DDB partitioning into hsw_wm_values as that's another piece of state we want to track. We don't read out the hardware state on init yet, so we can't really start using this yet, but it will be used later. Signed-off-by:

The fbc_wm_enabled member in intel_wm_config is useless for the time being. The original idea for it was that we'd pre-compute it and so that the WM merging process could know whether it needs to worry about FBC watermarks at all. But we don't have a convenient way to pre-check for the possibility of FBC being used. intel_update_fbc() should be split up for that. Signed-off-by:

On HSW the LP1,LP2,LP3 levels are either 1,2,3 or 1,3,4. We make the conversion from LPn to to the level at one point current. Later we're going to do it in a few places, so move it to a separate function. Signed-off-by:

Move the watermark max computations into haswell_update_wm(). This allows keeping the 1/2 vs. 5/6 split code in one place, and avoid having to pass around so many things. We also save a bit of stack space by only requiring one copy of struct hsw_wm_maximums. Also move the intel_wm_config out from hsw_compute_wm_parameters() and pass it it. We'll have some need for it in haswell_update_wm() later. Signed-off-by:
