* drm/nouveau: Fix pre-nv50 pageflip events (v4)Daniel Vetter2015-12-043-9/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apparently pre-nv50 pageflip events happen before the actual vblank period. Therefore that functionality got semi-disabled in commit af4870e406126b7ac0ae7c7ce5751f25ebe60f28 Author: Mario Kleiner <mario.kleiner.de@gmail.com> Date: Tue May 13 00:42:08 2014 +0200 drm/nouveau/kms/nv04-nv40: fix pageflip events via special case. Unfortunately that hack got uprooted in commit cc1ef118fc099295ae6aabbacc8af94d8d8885eb Author: Thierry Reding <treding@nvidia.com> Date: Wed Aug 12 17:00:31 2015 +0200 drm/irq: Make pipe unsigned and name consistent Triggering a warning when trying to sample the vblank timestamp for a non-existing pipe. There's a few ways to fix this: - Open-code the old behaviour, which just enshrines this slight breakage of the userspace ABI. - Revert Mario's commit and again inflict broken timestamps, again not pretty. - Fix this for real by delaying the pageflip TS until the next vblank interrupt, thereby making it accurate. This patch implements the third option. Since having a page flip interrupt that happens when the pageflip gets armed and not when it completes in the next vblank seems to be fairly common (older i915 hw works very similarly) create a new helper to arm vblank events for such drivers. v2 (Mario Kleiner): - Fix function prototypes in drmP.h - Add missing vblank_put() for pageflip completion without pageflip event. - Initialize sequence number for queued pageflip event to avoid trouble in drm_handle_vblank_events(). - Remove dead code and spelling fix. v3 (Mario Kleiner): - Add a signed-off-by and cc stable tag per Ilja's advice. v4 (Thierry Reding): - Fix kerneldoc typo, discovered by Michel Dänzer - Rearrange tags and changelog Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=106431 Cc: Thierry Reding <treding@nvidia.com> Cc: Mario Kleiner <mario.kleiner.de@gmail.com> Acked-by: Ben Skeggs <bskeggs@redhat.com> Cc: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Reviewed-by: Mario Kleiner <mario.kleiner.de@gmail.com> Cc: stable@vger.kernel.org # v4.3 Signed-off-by: Mario Kleiner <mario.kleiner.de@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: Fix an unwanted master inheritance v2Thomas Hellstrom2015-12-043-28/+67
| | | | | | | | | | | | | | | A client calling drmSetMaster() using a file descriptor that was opened when another client was master would inherit the latter client's master object and all its authenticated clients. This is unwanted behaviour, and when this happens, instead allocate a brand new master object for the client calling drmSetMaster(). Fixes a BUG() throw in vmw_master_set().

| * drm: imx: convert to drm_crtc_send_vblank_event()Russell King2015-11-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ipu_crtc_handle_pageflip() was calling drm_send_vblank_event() with a pipe argument of -1. Commit cc1ef118fc09 ("drm/irq: Make pipe unsigned and name consistent") now makes this error obvious, as we now may get a warning from: if (WARN_ON(pipe >= dev->num_crtcs)) in drm_vblank_count_and_time(). Prior to this change, we would end up making out-of-bounds array accesses via: struct drm_vblank_crtc *vblank = &dev->vblank[crtc]; and *vblanktime = vblanktimestamp(dev, pipe, cur_vblank); So, this has been broken for a very long time, and is not a result of the above commit. Since we don't care about the staging versions, I've tagged this with the earliest mainline commit where we do care, even though this commit did not introduce the bug.

For optimizing this we would need to add a new power domain, but it's not clear how much we would benefit given the short time we hold the reference. So for now let's keep things simple.

For now solve this keeping the current behavior and running the detection in this case too. For a proper solution Ville suggested to split the encoder into an HDMI and DP one, that can be done as a follow-up.

That function only takes the runtime PM reference which on VLV/CHV/BXT is not enough. We need the disp2d/pipe-a well on VLV/CHV and power well 2 on BXT. So add a new power domnain for gmbus and kill off the now unused intel_aux_display_runtime_get/put. And change intel_hdmi_set_edid() to use the gmbus power domain too since that's all we need there. Also toss in a BUILD_BUG_ON() to catch problems if we run out of bits for power domains. We're already really close to the limit...

As long as we're not actually enabling the port we don't need the lane power domains, and those are handled now purely from modeset_update_crtc_power_domains(). My initial motivation for this was to see if I could keep the DPIO power wells powered down while doing AUX on CHV, but turns out I can't so this doesn't change anything for CHV at least. But I think it's still a worthwile change. v2: Add case for PORT E. Default to POWER_DOMAIN_AUX_D for now.

Other drm-drivers set this offset to 0 before doing the mapping, so this looks like the correct way to go for rockchip as well.

This only occurs when building the vop driver as a module, when its built-in the initial setup happens to run before the clock framework shuts of unused clocks (including the aclk). While there also switch to doing prepare and enable in one step rather then separate steps to reduce the amount of code required.

This caused the inconsistency on a machine connected with a HDMI monitor; upon a hotplug event, the DDI port is suddenly switched to be handled as a DP although the same monitor is kept connected, and this leads to the erroneous blank output. This patch papers over the bug by excluding the previous HDMI encoder type from this override. This should be fixed more fundamentally, e.g. by moving the encoder type reset from the HPD or by having individual encoder objects for HDMI and DP. But since the bug has been present for a long time (3.17), it's better to have a quick-n-dirty fix for now, and keep working on a cleaner fix.

| * | drm/i915: Mark uneven memory banks on gen4 desktop as unknown swizzlingChris Wilson2015-11-231-9/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have varied reports of swizzling corruption on gen4 desktop, and confirmation that one at least is triggered by uneven memory banks (L-shaped memory). The implication is that the swizzling varies between the paired channels and the remainder of memory on the single channel. As the object then has unpredictable swizzling (it will vary depending on exact page allocation and may even change during the object's lifetime as the pages are replaced), we have to report to userspace that the swizzling is unknown. However, some existing userspace is buggy when it meets an unknown swizzling configuration and so we need to tell another white lie and mark the swizzling as NONE but report it as UNKNOWN through the extended get-tiling-ioctl. See commit 5eb3e5a5e11d14f9deb2a4b83555443b69ab9940 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sun Jun 28 09:19:26 2015 +0100 drm/i915: Declare the swizzling unknown for L-shaped configurations for the previous example where we found that telling the truth to userspace just ends up in a world of hurt. Also since we don't truly know what the swizzling is on the pages, we need to keep them pinned to prevent swapping as the reports also suggest that some gen4 devices have previously undetected bit17 swizzling. v2: Combine unknown + quirk patches to prevent userspace ever seeing unknown swizzling through the normal get-tiling-ioctl. Also use the same path for the existing uneven bank detection for mobile gen4.

To do this we need to calculate the offset based on which GPC we're executing on. This used to be done manually, but we've since found a "base" offset that can be added by the hardware. To use this, an extra bit needs to be set in the register address, which is what this macro achieves. There should be no functional change from this commit.
