2024-11-30drm/xe/display: Flush DMC wakelock release work on runtime suspendGustavo Sousa
We currently are not calling display runtime suspend functions when D3cold is not allowed. Because of that, we end up not disabling dynamic DC states (and do not go to DC9). With dynamic DC states enabled, we will also have DMC wakelock enabled. Since we use a delayed work to release the DMC wakelock, the work might get executed a little too late (after the PCI device has been put to D3hot) and we get a timeout warning ("DMC wakelock release timed out") because the MMIO for releasing the wakelock will be invalid after that point. To fix that, make sure we flush the release work at the end of xe_display_pm_runtime_suspend_late(). We can do that unconditionally because, if there is no pending work, that turns into a no-op.

2024-11-30drm/xe/display: Extract xe_display_pm_runtime_suspend_late()Gustavo Sousa
The current behavior for the runtime suspend case is that xe_display_pm_suspend_late() is only called when D3cold is allowed. Let's incorporate that behavior into a function specific to runtime PM and call it xe_display_pm_runtime_suspend_late(). With that, we keep stuff a bit more self-contained and allow having a place for adding more "late display runtime suspend"-related logic that isn't dependent on the "D3cold allowed" state. v2: - Fix typo in that caused xe_display_pm_runtime_suspend_late() to call itself instead of xe_display_pm_suspend_late(). - Add the empty version of xe_display_pm_runtime_suspend_late() for the !CONFIG_DRM_XE_DISPLAY case.

2024-10-11drm/xe/display: Separate the d3cold and non-d3cold runtime PM handlingImre Deak
For clarity separate the d3cold and non-d3cold runtime PM handling. The only change in behavior is disabling polling later during runtime resume. This shouldn't make a difference, since the poll disabling is handled from a work, which could run at any point wrt. the runtime resume handler. The work will also require a runtime PM reference, syncing it with the resume handler.

2024-10-04drm/i915: Plumb 'dsb' all way to the plane hooksVille Syrjälä
We need to be able to do both MMIO and DSB based pipe/plane programming. To that end plumb the 'dsb' all way from the top into the plane commit hooks. The compiler appears smart enough to combine the branches from all the back-to-back register writes into a single branch. So the generated asm ends up looking more or less like this: plane_hook() { if (dsb) { intel_dsb_reg_write(); intel_dsb_reg_write(); ... } else { intel_de_write_fw(); intel_de_write_fw(); ... } } which seems like a reasonably efficient way to do this. An alternative I was also considering is some kind of closure (register write function + display vs. dsb pointer passed to it). That does result is smaller code as there are no branches anymore, but having each register access go via function pointer sounds less efficient. Not that I actually measured the overhead of either approach yet. Also the reg_rw tracepoint seems to be making a huge mess of the generated code for the mmio path. And additionally there's some kind of IS_GSI_REG() hack in __raw_uncore_read() which ends up generating a pointless branch for every mmio register access. So looks like there might be quite a bit of room for improvement in the mmio path still.

2024-10-03drm/i915/irq: add struct i915_irq_regs tripletJani Nikula
Add struct i915_irq_regs to hold IMR/IER/IIR register offsets to pass to gen3_irq_reset() and gen3_irq_init(). This helps in grouping the registers and further cleanup. Note: gen3_irq_reset() and gen3_irq_init() really did have the IMR/IER/IIR parameters in different order.

2024-09-26drm/xe: Move IRQ-related registers to dedicated headerMatt Roper
IRQ registers have a well-defined scope and make sense to collect in a dedicated header file. This also reduces confusion about the GT IRQ registers --- even though those registers relate to the GTs, they actually live outside the GT (in the sgunit) and thus do not need to worry about GT-specific register concepts like forcewake, steering, etc. Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Gustavo Sousa <gustavo.sousa@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240923214514.2031410-2-matthew.d.roper@intel.com
