Add an ID for the HSW/BDW global display power well for consistency. The ID is selected so that it can be used to get at the HW request and status flags with the corresponding GEN9+ macros. Unifying the HSW/BDW and GEN9+ versions of these macros and the power well ops using them will be done in follow-up patches. v2: - Rebased on v2 of patch 2. Signed-off-by:

Power well IDs are used for lookup so they must be unique. To ensure this assign the always-on power well ID everywhere where it's missing. This didn't cause a problem so far, since we didn't need to look up power wells that happened to share their IDs. Signed-off-by:
-
Imre Deak authored
Atm, the power well IDs are defined in separate platform specific enums, which isn't ideal for the following reasons: - the IDs are used by helpers like lookup_power_well() in a platform independent way - the always-on power well is used by multiple platforms and so needs now separate IDs, although these IDs refer to the same thing To make things more consistent use a single enum instead of the two separate ones, listing the IDs per platform (or set of very similar platforms like all GEN9/10). Replace the separate always-on power well IDs with a single ID. While at it also add a note clarifying the distinction between regular power wells that follow a common programming pattern and custom ones that are programmed in some other way. The IDs for regular power wells need to stay fixed, since they also define the request and state HW flag positions in their corresponding power well control register(s). v2: - Add comment about id to req,status bit mapping to the enum.

The power well IDs are used for lookup, so they must be unique on a given platform; ensure this on CHV. This didn't cause an actual problem since we didn't need to look up power wells which happened to share an ID. Mark this new power well as custom, since its programming pattern doesn't follow that of the rest of VLV/CHV power wells. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

The crtc state starts out being bzero'd, so no need to clear scaler_users. Also intel_crtc_init_scalers() knows already which platforms have scalers, so no need for the platform check here. Similarly intel_crtc_init_scalers() will init scaler_id as required, so no need to do it here separately.

The scaler allocation code depends on a non-zero default value for the crtc scaler_id, so make sure we initialize the scaler state accordingly even if the crtc is off. This fixes at least an initial YUV420 modeset (added in a follow-up patchset by Shashank) when booting with the screen off: after the initial HW readout and modeset which enables the scaler a subsequent modeset will disable the scaler which isn't properly allocated. This results in a funky HW state where the pipe scaler HW registers can't be modified and the normally black screen is grey and shifted to the right or jitters. The problem was revealed by Shashank's YUV420 patchset and first reported by Ville. v2: - In the stable tag also include versions which need backporting (Jani) Cc: Jani Nikula <jani.nikula@intel.com> Cc: Shashank Sharma <shashank.sharma@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Chandra Konduru <chandra.konduru@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: <stable@vger.kernel.org> # 4.2.x Reported-by:

Although a banned context will be told to -EIO off if they try to submit more requests, we have a discrepancy between whole device resets and per-engine resets where we report the GPU reset but not the engine resets. This leaves a bit of mystery as to why the context was banned, and also reduces awareness overall of when a GPU (engine) reset occurs with its possible side-effects. Signed-off-by:

intel_engine_init_globa_seqno() may be called from an uncontrolled set-wedged path where we have given up waiting for broken hw and declare it defunct. Along that path, any sanity checks that the hw is idle before we adjust its state will expectedly fail, so we simply cannot. Instead of asserting inside init_global_seqno, we move them to the normal caller reset_all_global_seqno() as it handles runtime seqno wraparound. Signed-off-by:

Chris Wilson authored
Before we declare an engine as idle, check if there are any pending execlist context-switches and if the ring itself reports as idle. Otherwise, we may be left in a situation where we miss a crucial execlist event (or something more sinister) yet the requests complete. Since the seqno write happens, we believe the engine to be truly idle. Signed-off-by:

Chris Wilson authored
When doing a GPU reset, the CSB register will be trashed and we will lose any context-switch notifications that happened since the tasklet was disabled. If we find that all requests on this engine were completed, we want to make sure that the ELSP tracker is similarly empty so that we do not feed back in the completed requests upon recovering from the reset. Signed-off-by:
-
Chris Wilson authored
We rely on disabling the execlists (by stopping the tasklet) to prevent new requests from submitting to the engine ELSP before we are ready. However, we re-enable the engine before we call init_hw which gives userspace the opportunity to subit a new request which is then overwritten by init_hw -- but not before the HW may have started executing. The subsequent out-of-order CSB is detected by our sanity checks in intel_lrc_irq_handler(). Fixes: a1ef70e1 ("drm/i915: Add support for per engine reset recovery") Signed-off-by:

FB helper code falls back to a 1024x768 mode if no outputs are connected or don't report back any modes upon initialization. This can be annoying because outputs that are added to FB helper later on can't be used with FB helper if they don't support a matching mode. The fallback is in place because VGA connectors can happen to report an unknown connection status even when they are in fact connected. Some drivers have custom solutions in place to defer FB helper setup until at least one output is connected. But the logic behind these solutions is always the same and there is nothing driver-specific about it, so a better alterative is to fix the FB helper core and add support for all drivers automatically. This patch adds support for deferred FB helper setup. It checks all the connectors for their connection status, and if all of them report to be disconnected marks the FB helper as needing deferred setup. Whet setup is deferred, the FB helper core will automatically retry setup after a hotplug event, and it will keep trying until it succeeds. v2: Rebase onto my entirely reworked fbdev helper locking. One big difference is that this version again drops&reacquires the fbdev lock (which is now fb_helper->lock, but before this patch series it was mode_config->mutex), because register_framebuffer must be able to recurse back into fbdev helper code for the initial screen setup. v3: __drm_fb_helper_initial_config must hold fb_helper->lock upon return, I've fumbled that in the deferred setup case (Liviu). v4: I was blind, redo this all. __drm_fb_helper_initial_config shouldn't need to reacquire fb_helper->lock, that just confuses callers. I myself got confused by kernel_fb_helper_lock and somehow thought it's the same as fb_helper->lock. Tsk. Also simplify the logic a bit (we don't need two functions to probe connectors), we can stick much closer to the existing code. And update some comments I've spotted that are outdated. v5: Don't pass -EAGAIN to drivers, it's just an internal error code (Liviu). v6: Add _and_unlock suffix to clarify locking (Maarten) Cc: Liviu Dudau <liviu@dudau.co.uk> Cc: John Stultz <john.stultz@linaro.org> Cc: Thierry Reding <treding@nvidia.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Tested-by:

drm_atomic_helper_swap_state() will be changed to interruptible waiting in the next few commits, so all drivers have to be changed to handling failure. VC4 has its own nonblocking modeset tracking through the vc4->async_modeset semaphore, so it doesn't need to stall in swap_state. Pass stall = false and BUG_ON when it returns an error. This should never happen for !stall. Signed-off-by:
