2017-05-19drm/pl111: Register the clock divider and use it.Eric Anholt4-24/+158
This is required for the panel to work on bcm911360, where CLCDCLK is the fixed 200Mhz AXI41 clock. The rate set is still passed up to the CLCDCLK, for platforms that have a settable rate on that one. v2: Set SET_RATE_PARENT (caught by Linus Walleij), depend on COMMON_CLK. v3: Mark the clk_ops static (caught by Stephen).

2017-05-19drm/i915/g4x: Improve gpu reset reliabilityMika Kuoppala1-0/+35
ELK seems to very picky about the preconditions to reset. Evidence on Eaglelake (8086:2e12 (rev 03)) shows that it does not like if reset occurs when there is active ring. Ville found out that there is workaround with name 'WaMediaResetMainRingCleanup' which suggests that we need to cleanup rings before resetting. It is unclear what cleanup exactly means but evidence shows that stopping the ring does have an effect on reset reliability. This patch makes reset successful on hangs induced by chained batches (the igt ones). Note that if the hang is inside a shader, it is possible that our attempts to stop the ring achieves anything. v2: zero ctl,head,tail also. bug ref. use driver debugs (Chris) v3: specify platform on testcases, comment tidyup (Chris) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=100942 Testcase: igt/gem_busy/*-hang #elk Testcase: igt/gem_ringfill/hang-* #elk Suggested-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tomi Sarvela <tomi.p.sarvela@intel.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: http://patchwork.freedesktop.org/patch/msgid/20170519091340.21439-1-mika.kuoppala@intel.com

2017-05-19drm/i915: set initialised only when init_context callback is NULLChuanxiao Dong1-1/+1
During execlist_context_deferred_alloc() we presumed that the context is uninitialised (we only just allocated the state object for it!) and chose to optimise away the later call to engine->init_context() if engine->init_context were NULL. This breaks with GVT's contexts that are marked as pre-initialised to avoid us annoyingly calling engine->init_context(). The fix is to not override ce->initialised if it is already true.

drm_of_find_panel_or_bridge() is expecting np to point to the encoder node, not the bridge or panel this encoder is feeding. Moreover, the endpoint parameter passed to drm_of_find_panel_or_bridge() is always set to zero, which prevents us from probing all outputs. We also move the atmel_hlcdc_rgb_output allocation after the panel/bridge detection to avoid useless allocations.

2017-05-18drm/i915: Do not sync RCU during shrinkingJoonas Lahtinen1-5/+0
Due to the complex dependencies between workqueues and RCU, which are not easily detected by lockdep, do not synchronize RCU during shrinking. On low-on-memory systems (mem=1G for example), the RCU sync leads to all system workqueus freezing and unrelated lockdep splats are displayed according to reports. GIT bisecting done by J. R. Okajima points to the commit where RCU syncing was extended. RCU sync gains us very little benefit in real life scenarios where the amount of memory used by object backing storage is dominant over the metadata under RCU, so drop it altogether. " Yeeeaah, if core could just, go ahead and reclaim RCU queues, that'd be great.

2017-05-17drm/i915/skl+: use linetime latency if ddb size is not availableKumar, Mahesh2-9/+40
This patch make changes to use linetime latency if allocated DDB size during plane watermark calculation is not available. linetime is the time, display engine takes to fetch one line worth of pixels with given pixel clock rate. This is required to implement new DDB allocation algorithm. In New Algorithm DDB is allocated based on WM values, because of which number of DDB blocks will not be available during WM calculation, So this "linetime latency" is suggested by SV/HW team to be used during switch-case for WM blocks selection. linetime latency us = pipe horizontal total pixels/adjusted pixel rate MHz Changes since v1: - Rebase on top of Paulo's patch series Changes since v2: - Fix if-else condition (pointed by Maarten) Changes since v3: - Use common function for timetime_us calculation (Paulo) - rebase on drm-tip Changes since v4: - Use consistent name for fixed_point operation Changes since v5: - Improve commit message - rename skl_get_linetime_us to intel_get_linetime_us - fix watermark result selection (Matt) Signed-off-by: "Mahesh Kumar" <mahesh1.kumar@intel.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170517115831.13830-11-mahesh1.kumar@intel.com

This patch cleanup/reorganises the watermark calculation functions. This patch make use of already available macro "drm_atomic_crtc_state_for_each_plane_state" to walk through plane_state list instead of calculating plane_state in function itself. This restructuring will help later patch for new DDB allocation algorithm to do only algo related changes.

2017-05-17drm/i915/skl+: Fail the flip if ddb min requirement exceeds pipe allocationKumar, Mahesh1-2/+11
DDB minimum requirement of crtc configuration (cumulative of all the enabled planes in crtc) may exceed the allocated DDB for crtc/pipe. This patch make changes to fail the flip/ioctl if minimum requirement for pipe exceeds the total ddb allocated to the pipe. Previously it succeeded but making alloc_size a negative value. Which will make subsequent calculations for plane ddb allocation bogus & may lead to screen corruption or system hang.
