| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 041824ee25cfc535ba2d9a22c217df735ea2471e. We have latency issues that might impact the performance: #96606. and hangs and loading issues on resume after S4: #96526. This is also blocking a platform milestone so let's disable this for now while we make sure we don't have any more loading issue, or related basic hangs and it pass BAT for real in all platofmrs. In case BAT is wrong let's first fix BAT before re-enable it here.

| * drm/i915/bxt: Fix inadvertent CPU snooping due to incorrect MOCS configImre Deak2016-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting a write-back cache policy in the MOCS entry definition also implies snooping, which has a considerable overhead. This is unexpected for a few reasons: - From user-space's point of view since it didn't want a coherent surface (it didn't set the buffer as such via the set caching IOCTL). - There is a separate MOCS entry field for snooping (which we never set). - This MOCS table is about caching in (e)LLC and there is no (e)LLC on BXT. There is a separate table for L3 cache control. Considering the above the current behavior of snooping looks like an unintentional side-effect of the WB setting. Changing it to be LLC-UC gets rid of the snooping without any ill-effects. For a coherent surface the application would use a separate MOCS entry at index 1 and call the set caching IOCTL to setup the PTE entries for the corresponding buffer to be snooped. In the future we could also add a new MOCS entry for coherent surfaces. This resulted in 70% improvement in synthetic texturing benchmarks. Kudos to Valtteri Rantala, Eero Tamminen and Michael T Frederick and Ville who helped to narrow the source of problem to the kernel and to the snooping behaviour in particular. With a follow-up change to adjust the 3rd entry value igt/gem_mocs_settings is passing after this change. v2: - Rebase on v2 of patch 1/2. v3: - Set the entry as LLC uncached instead of PTE-passthrough. This way we also keep snooping disabled, but we also make the cacheability/ coherency setting indepent of the PTE which is managed by the kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i915 driver is now using atomic properties and atomic commit to handle the legacy set gamma IOCTL. However, if the driver is configured without atomic (nuclear_pageflip = false), it won't update the legacy properties for degamma_lut, gamma_lut and ctm leaving them out of sync with the atomic version of the properties. Until the driver is full atomic, make sure we update the non-atomic version of the properties. v2: Update the comment with a FIXME.

| * drm/i915: Enable polling when we don't have hpdLyude2016-07-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, there's two situations where we lose hpd right now: - Runtime suspend - When we've shut off all of the power wells on Valleyview/Cherryview While it would be nice if this didn't cause issues, this has the ability to get us in some awkward states where a user won't be able to get their display to turn on. For instance; if we boot a Valleyview system without any monitors connected, it won't need any of it's power wells and thus shut them off. Since this causes us to lose HPD, this means that unless the user knows how to ssh into their machine and do a manual reprobe for monitors, none of the monitors they connect after booting will actually work. Eventually we should come up with a better fix then having to enable polling for this, since this makes rpm a lot less useful, but for now the infrastructure in i915 just isn't there yet to get hpd in these situations. Changes since v1: - Add comment explaining the addition of the if (!mode_config->poll_running) in intel_hpd_init() - Remove unneeded if (!dev->mode_config.poll_enabled) in i915_hpd_poll_init_work() - Call to drm_helper_hpd_irq_event() after we disable polling - Add cancel_work_sync() call to intel_hpd_cancel_work() Changes since v2: - Apparently dev->mode_config.poll_running doesn't actually reflect whether or not a poll is currently in progress, and is actually used for dynamic module paramter enabling/disabling. So now we instead keep track of our own poll_running variable in dev_priv->hotplug - Clean i915_hpd_poll_init_work() a little bit Changes since v3: - Remove the now-redundant connector loop in intel_hpd_init(), just rely on intel_hpd_poll_enable() for setting connector->polled correctly on each connector - Get rid of poll_running - Don't assign enabled in i915_hpd_poll_init_work before we actually lock dev->mode_config.mutex - Wrap enabled assignment in i915_hpd_poll_init_work() in READ_ONCE() for doc purposes - Do the same for dev_priv->hotplug.poll_enabled with WRITE_ONCE in intel_hpd_poll_enable() - Add some comments about racing not mattering in intel_hpd_poll_enable Changes since v4: - Rename intel_hpd_poll_enable() to intel_hpd_poll_init() - Drop the bool argument from intel_hpd_poll_init() - Remove redundant calls to intel_hpd_poll_init() - Rename poll_enable_work to poll_init_work - Add some kerneldoc for intel_hpd_poll_init() - Cross-reference intel_hpd_poll_init() in intel_hpd_init() - Just copy the loop from intel_hpd_init() in intel_hpd_poll_init() Changes since v5: - Minor kerneldoc nitpicks Cc: stable@vger.kernel.org Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Lyude <cpaul@redhat.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> (cherry picked from commit 19625e85c6ec56038368aa72c44f5f55b221f0fc)
| * drm/i915/vlv: Disable HPD in valleyview_crt_detect_hotplug()Lyude2016-07-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the things preventing us from using polling is the fact that calling valleyview_crt_detect_hotplug() when there's a VGA cable connected results in sending another hotplug. With polling enabled when HPD is disabled, this results in a scenario like this: - We enable power wells and reset the ADPA - output_poll_exec does force probe on VGA, triggering a hpd - HPD handler waits for poll to unlock dev->mode_config.mutex - output_poll_exec shuts off the ADPA, unlocks dev->mode_config.mutex - HPD handler runs, resets ADPA and brings us back to the start This results in an endless irq storm getting sent from the ADPA whenever a VGA connector gets detected in the middle of polling.

| * drm/i915/vlv: Reset the ADPA in vlv_display_power_well_init()Lyude2016-07-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While VGA hotplugging worked(ish) before, it looks like that was mainly because we'd unintentionally enable it in valleyview_crt_detect_hotplug() when we did a force trigger. This doesn't work reliably enough because whenever the display powerwell on vlv gets disabled, the values set in VLV_ADPA get cleared and consequently VGA hotplugging gets disabled. This causes bugs such as one we found on an Intel NUC, where doing the following sequence of hotplugs: - Disconnect all monitors - Connect VGA - Disconnect VGA - Connect HDMI Would result in VGA hotplugging becoming disabled, due to the powerwells getting toggled in the process of connecting HDMI. Changes since v3: - Expose intel_crt_reset() through intel_drv.h and call that in vlv_display_power_well_init() instead of encoder->base.funcs->reset(&encoder->base); Changes since v2: - Use intel_encoder structs instead of drm_encoder structs Changes since v1: - Instead of handling the register writes ourself, we just reuse intel_crt_detect() - Instead of resetting the ADPA during display IRQ installation, we now reset them in vlv_display_power_well_init() Cc: stable@vger.kernel.org Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Lyude <cpaul@redhat.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> [danvet: Rebase over dev_priv/drm_device embedding.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> (cherry picked from commit 9504a89247595b6c066c68aea0c34af1fc78d021)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to gen6 we didn't have per-ring IMR registers, which means that since commit 61ff75ac20ff ("drm/i915: Simplify enabling user-interrupts with L3-remapping") we're now masking off all interrupts when init_render_ring() gets called.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Never go to sleep waiting on the GPU without first ensuring that we will get woken up. We have a choice of queuing the hangcheck before every schedule() or the first time we wakeup. In order to simply accommodate both the signaler and the ordinary waiter, move the queuing to the common point of enabling the irq. We lose the paranoid safety of ensuring that the hangcheck is active before the sleep, but avoid code duplication (and redundant hangcheck queuing).

But the remaining warnings have completely bogus line and probably also file sources, and I just can't find them. Probably some serious debuggging of the line annotations in the sphinx/kernel-doc toolchain needed first.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The drm_irq docs want one function from drmP.h, but that one is a serious mess. Extract it, and while at it improve the docs a bit. There's a bit a header loop issue since core data structures like drm_device and drm_driver aren't in their own headers yet, which means the drm_irq.h include in drmP.h needs to be in just the right spot :( Also noticed that drm_vblank_crtc->last_wait is entirely unused, remove it. v2: git add drm_irq.h ...
