All platforms using the shared DPLL framework use 3 reference clocks for their DPLLs: SSC, non-SSC and DSI. For a more unified way across platforms store the frequency of these ref clocks as part of the DPLL global state. This also allows us to keep the HW access reading out the ref clock value separate from the DPLL frequency calculation that depends on the ref clock. For now add only the SSC and non-SSC ref clocks, as the pre-ICL DSI code has its own logic for calculating DPLL parameters instead of the shared DPLL framework. v2: - Apply the ICL combo PHY PLL ref_clock/2 adjustment during the frequency->PLL param conversion direction as well.

For clarity keep the SKL DPLL ref clock in a variable instead of open-coding it. Store the value in kHZ units as done on other platforms. This allows us in a later patch to keep track of the DPLL ref clock in a more unified way across all platforms. Signed-off-by:

Move all the DPLL params->DPLL frequency conversion functions to intel_dpll_mgr.c where the corresponding inverse conversions are. The GEN11+ TBT PLL outputs multiple frequencies and for selecting the one in use we need to check the DDI CLK mux. As part of the DDI clock logic this selection is kept in intel_ddi.c. Signed-off-by:

There seems to be a bit of confusing redundancy in a way, how plane data rate/min cdclk are calculated. In fact both min cdclk, pixel rate and plane data rate are all part of the same formula as per BSpec. However currently we have intel_plane_data_rate, which is used to calculate plane data rate and which is also used in bandwidth calculations. However for calculating min_cdclk we have another piece of code, doing almost same calculation, but a bit differently and in a different place. However as both are actually part of same formula, probably would be wise to use plane data rate calculations as a basis anyway, thus avoiding code duplication and possible bugs related to this. Another thing is that I've noticed that during min_cdclk calculations we account for plane scaling, while for plane data rate, we don't. crtc->pixel_rate seems to account only for pipe ratio, however it is clearly stated in BSpec that plane data rate also need to account plane ratio as well. So what this commit does is: - Adds a plane ratio calculation to intel_plane_data_rate - Removes redundant calculations from skl_plane_min_cdclk which is used for gen9+ and now uses intel_plane_data_rate as a basis from there as well. v2: - Don't use 64 division if not needed(Ville Syrjälä) - Now use intel_plane_pixel_rate as a basis for calculations both at intel_plane_data_rate and skl_plane_min_cdclk(Ville Syrjälä) v3: - Again fix the division macro - Fix plane_pixel_rate to pixel_rate at intel_plane_pixel_rate callsites v4: - Renamed skl_plane_ratio function back(Ville Syrjälä) v5: - Don't precalculate plane pixel rate for invisible plane, check for visibility first, as in invisible case it will have dst_w and dst_h equal to zero, causing divide error. v6: - Removed useless warn in intel_plane_pixel_rate(Ville Syrjälä) - Fixed alignment in intel_plane_data_rate(Ville Syrjälä) - Changed pixel_rate type to be unsigned int in skl_plane_min_cdclk(Ville Syrjälä) Signed-off-by:Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Signed-off-by:

The preferred style is to sprinkle commas after each array and structure initialization, whether or not it happens to be the last element/member (only exception being sentinel entries which never have anything after them). This leads to much prettier diffs if/when new elements/members get added to the end of the initialization. We're not bound by some ancient silly mandate to omit the final comma.

Some devices with a builtin panel have the panel mounted upside down, this is indicated by the rotate_180 bit in the BDB_GENERAL_FEATURES VBT block. We store this info in dev_priv->vbt.orientation, use this to set the connector's orientation property so that fbcon and userspace will show the image the right way up on devices with an upside-down mounted panel. This fixes the image being upside-down on a Teclast X89 tablet. Signed-off-by:

Commit 82daca29 ("drm/i915: Add "panel orientation" property to the panel connector, v6.") uses hardware state readback to determine if the GOP is rotating the image by 180 degrees to compensate for upside-down mounted panels. When I wrote that commit I tried to find the VBT bits the GOP used to decide to rotate the image, but I could not find them. Back then I only looked at the rotation bits in struct mipi_config and these read 0 on the 1 BYT device I have with an upside-down mounted panel (a GP-electronic T701 tablet). While working on a similar problem on a BYT device with an eDP panel I noticed that the new intel_dsi_get_panel_orientation() helper which gets used on newer SoCs (Apollo-Lake, etc.) checks the rotate_180 bit in the BDB_GENERAL_FEATURES VBT block. I've checked and this bit indeed is set on the GP-electronic T701 tablet, so using the generic intel_dsi_get_panel_orientation() helper there does the right thing without needing any extra readback of hw state. This commit removes the special handling of the panel orientation for DSI panels on BYT/CHT devices, bringing the handling in line with the handling of DSI panels on other devices. Reviewed-by:

We monitor the health of the system via periodic heartbeat pulses. The pulses also provide the opportunity to perform garbage collection. However, we interpret an incomplete pulse (a missed heartbeat) as an indication that the system is no longer responsive, i.e. hung, and perform an engine or full GPU reset. Given that the preemption granularity can be very coarse on a system, we let the sysadmin override our legacy timeouts which were "optimised" for desktop applications. The heartbeat interval can be adjusted per-engine using, /sys/class/drm/card?/engine/*/heartbeat_interval_ms Signed-off-by:

After initialising a preemption request, we give the current resident a small amount of time to vacate the GPU. The preemption request is for a higher priority context and should be immediate to maintain high quality of service (and avoid priority inversion). However, the preemption granularity of the GPU can be quite coarse and so we need a compromise. The preempt timeout can be adjusted per-engine using, /sys/class/drm/card?/engine/*/preempt_timeout_ms and can be disabled by setting it to 0. Signed-off-by:

When we allow ourselves to sleep before a GPU reset after disabling submission, even for a few milliseconds, gives an innocent context the opportunity to clear the GPU before the reset occurs. However, how long to sleep depends on the typical non-preemptible duration (a similar problem to determining the ideal preempt-reset timeout or even the heartbeat interval). As this seems of a hard policy decision, punt it to userspace. The timeout can be adjusted using /sys/class/drm/card?/engine/*/stop_timeout_ms Signed-off-by:

We busywait on an inflight request (one that is currently executing on HW, and so might complete quickly) prior to setting up an interrupt and sleeping. The trade off is that we keep an expensive CPU core busy in order to avoid wake up latency: where that trade off should lie is best left to the sysadmin. The busywait mechanism can be compiled out with ./scripts/config --set-val DRM_I915_SPIN_REQUEST 0 The maximum busywait duration can be adjusted per-engine using, /sys/class/drm/card?/engine/*/ms_busywait_duration_ns Signed-off-by:

Execlists uses a scheduling quantum (a timeslice) to alternate execution between ready-to-run contexts of equal priority. This ensures that all users (though only if they of equal importance) have the opportunity to run and prevents livelocks where contexts may have implicit ordering due to userspace semaphores.

Use the per-engine sysfs directory to let userspace discover the mmio_base of each engine. Prior to recent generations, the user accessible registers on each engine are at a fixed offset relative to each engine -- but require absolute addressing. As the absolute address depends on the actual physical engine, this is not always possible to determine from userspace (for example icl may expose vcs1 or vcs2 as the second vcs engine). Make this easy for userspace to discover by providing the mmio_base in sysfs. Signed-off-by:

Preliminary stub to add engines underneath /sys/class/drm/cardN/, so that we can expose properties on each engine to the sysadmin. To start with we have basic analogues of the i915_query ioctl so that we can pretty print engine discovery from the shell, and flesh out the directory structure. Later we will add writeable sysadmin properties such as per-engine timeout controls.

An odd and highly unlikely path caught us out. On delayed submission (due to an asynchronous reset handler), we poked the priority_hint and kicked the tasklet.
