HSW has some special requirements for the VEBOX. Splitting out the interrupt handler will make the code a bit nicer and less error prone when we begin to handle those. The slight functional change in this patch (queueing work while holding the spinlock) is intentional as it makes a subsequent patch a bit nicer. The change should also only effect HSW platforms.

Now we compute the results for both 1/2 and 5/6 partitioning and then use hsw_find_best_result to choose which one to use. With this patch, Haswell watermarks support should be in good shape. The only improvement we're missing is the case where the primary plane is disabled: we always assume it's enabled, so we take it into consideration when calculating the watermarks. v2: - Check the latency when finding the best result Signed-off-by:

We were previously only setting the WM_PIPE registers, now we are setting the LP watermark registers. This should allow deeper PC states, resulting in power savings. We're only using 1/2 data buffer partitioning for now. v2: Merge both hsw_compute_pri_wm_* functions (Ville) v3: - Simplify hsw_compute_wm_results (Ville) - Rebase due to changes on the previous patch v4: Unconfuse wm_lp/level (Ville) Signed-off-by: -
Paulo Zanoni authored
We were previously calling sandybridge_update_wm on HSW, but the SNB function didn't really match the HSW specification, so we were just writing the wrong values. With this patch, the haswell_update_wm function will set the correct values for the WM_PIPE registers, but it will still keep all the LP watermarks disabled. The patch may look a little bit over-complicated for now, but it's because much of the infrastructure for setting the LP watermarks is already in place, so we won't have too much code churn on the patch that sets the LP watermarks. v2: - Fix pixel_rate on panel fitter case (Ville) - Try to not overflow (Ville) - Remove useless variable (Ville) - Fix p->pri_horiz_pixels (Paulo) v3: - Fix rounding errors on hsw_wm_method2 (Ville) v4: - Fix memcmp bug (Paulo) Signed-off-by: -

Historically we considered the render ring to have special flush semantics and everything else to fall under a more general umbrella. Probably by coincidence more than anything we decided to make the bsd ring have the default *other* flush. As the new vebox ring exposes, the bsd ring is actually the weird one. Doing this allows us to call gen6_ring_flush for the vebox because calling blt_ring_flush would be weird... This patch should have no functional change. Reviewed-by:

Like the other rings, the VECS supports semaphores. The semaphore stuff is a bit wonky so this patch on it's own should be nice for review. This patch should have no functional impact. v2: Fix the English parts of clarification (again, register names were right, text was reversed) (Damien) Restore the still valid invariant.

The video enhancement command streamer is a new ring on HSW which does what it sounds like it does. This patch provides the most minimal inception of the ring. In order to support a new ring, we need to bump the number. The patch may look trivial to the untrained eye, but bumping the number of rings is a bit scary. As such the patch is not terribly useful by itself, but a pretty nice place to find issues during a bisection. Reviewed-by:

This replaces the existing MBOX update code with a more generalized calculation for emitting mbox updates. We also create a sentinel for doing the updates so we can more abstractly deal with the rings. When doing MBOX updates the code must be aware of the /other/ rings. Until now the platforms which supported semaphores had a fixed number of rings and so it made sense for the code to be very specialized (hardcoded). The patch does contain a functional change, but should have no behavioral changes. Signed-off-by:

Semaphores are tied very closely to the rings in the GPU. Trivial patch adds comments to the existing code so that when we add new rings we can include comments there as well. It also helps distinguish the ring to semaphore mailbox interactions by using the ringname in the semaphore data structures. This patch should have no functional impact. v2: The English parts (as opposed to register names) of the comments were reversed. (Damien) Signed-off-by:

It appears that a beneficial side-effect of Mika's more accurate hangman work is to speed up hang detection and execution. This exposes a bug in the reset code that then treats repeated simulated hangs as an indication that the machine is wedged. Jiggle the code around so that we only do the simulation processing from the hangcheck and avoid confusing it with a real hang.

All this pipe config abstraction adds another layer of complexity, so it's good to have better visibility into what's going on exactly. Doesn't dump out everything yet, and some bits are a bit duplicated but this should be a good start. Note that at boot-up a lot of the fields are 0 even for enabled pipes, this is simply because our hw state readout code doesn't support everything. v2: Remove a few more now redudant debug output lines. v3: Review from Paulo - use transcoder_name - fix up format specifiers - add missing ':' in debug output Cc: Paulo Zanoni <przanoni@gmail.com> Reviewed-by:

In the cloned case, changing just one output but keeping the other, the pipe state won't change and intel_crtc_update_dpms will be a nop, but we still need to update the dpms state of the output being changed. Only dvo, sdvo and crt are cloneable, so only those three have special dpms functions. Signed-off-by:

Well, as well as we can without completely revamping the drm vblank code. The issue are that - The vblank code needs to work on both ums and kms. - It deals always deals with pipes. - It doesn't take any of the kms locks. The last part is not really fixable without revamping the drm vblank code, since the drm core <-> driver interactions is a veritable pile of spaghettis. But the other pieces can be fixed by switching on the MODESET driver flag and either checking the hw state directly (ums case) or just querying our sw tracking (with broken locking, but that's not worse than what we've had). Note that this essentially reverts commit 702e7a56 Author: Paulo Zanoni <paulo.r.zanoni@intel.com> Date: Tue Oct 23 18:29:59 2012 -0200 drm/i915: convert PIPECONF to use transcoder instead of pipe for the ums case, which will fix a NULL deref (since we really don't have any crtcs set up). But the real reason to do this is to drop our reliance on the cpu_transcoder: By only checking intel_crtc->active we don't need to make sure that the pipe_config (or at least the cpu_transcoder) contain safe values even when the pipe is off.

The patch changes all remaining is_cpu_edp() check with a check for port A. We can do this, since in all these cases ValleyView is handled separately and port A is always a CPU side eDP port. Signed-off-by:

On ValleyView for both eDP and DP the AUX input clock is 200MHz, so we can calculate for both the clock divider for the 2MHz target rate at the same place. Afterwards we can also replace the is_cpu_edp() check with a check for port A. Signed-off-by:

Based on 3739850b - "drm/i915: disable the cpu edp port after the cpu pipe" and the bspec disabling sequence for IVB and older it seems we have to distinguish only the CPU vs. PCH port case, whether it's a DP or eDP doesn't seem to matter. For IVB and older on the CPU side we can only have eDP on port A, DP ports can only be on the PCH side. On VLV we have only CPU side eDP/DP ports, no PCH. So the condition for the disabling sequence we need for CPU ports is port == A || IS_VLV. This allows us to remove is_cpu_edp() completely in a later patch. v2: - simplify (and fix) the condition for CPU side ports and adjust the commit message accordingly (Daniel) Signed-off-by:

If contexts were actually initialized, and we fail somewhere later during init this would possibly leak memory, and lead to some error messages about unclean takedown. As the odds of this occurring, and someone actually caring/noticing are pretty slim, the patch isn't terribly important. Found by code inspection while working on something else. Signed-off-by:

Add some debug messages to help figure out what goes wrong on context initialization. Later in the PPGTT series, I ended up having a lot of failures after reset. In many cases it was extra difficult to debug because I hadn't even realized that contexts failed to reinitialize after reset (again an artifact of some later patches). This fairly benign patch does help debug some potential issues which arise later. Signed-off-by:

The GTT start is either 0 in the KMS case, or some value which is set only after the init IOCTL in the UMS case. In both cases, we don't have this information until after we've tried to kick out the firmware fb. This patch should have no functional change since we kzalloc the GTT struct anyway. It only clarifies the situation for people who end up having to look at that code.

On Haswell, whenever we change the sprites we need to completely recalculate all the watermarks, because the sprites are one of the parameters to the LP watermarks, so a change on the sprites may trigger a change on which LP levels are enabled. So on this commit we store all the parameters we need to store for proper recalculation of the Haswell WMs and then call haswell_update_wm. Notice that for now our haswell_update_wm function is not really using these parameters we're storing, but on the next commits we'll use these parameters. Signed-off-by:

Paulo Zanoni authored
Because we want to call it from the "sprite disable" paths, since on Haswell we need to update the sprite watermarks when we disable sprites. For now, all this patch does is to add the "enable" argument and call intel_update_sprite_watermarks from inside ivb_disable_plane. This shouldn't change how the code behaves because on sandybridge_update_sprite_wm we just ignore the "!enable" case. The patches that implement Haswell watermarks will make use of the changes introduced by this patch. Signed-off-by:
