For patches 2, 4, 5, 6, 7, 19: Reviewed-by: Paulo Zanoni <paulo.r.zanoni@xxxxxxxxx> However, I tested these patches on a HSW Machine with eDP+HDMI, and there are WARNs on dmesg for the dpms-non-lpsp subtest. I found at least two problems: 1 - Function hsw_ddi_pll_get_hw_state() reads registers while the device is suspended. 2 - When _intel_set_mode() calls intel_crtc_disable(), it calls assert_plane() which reads register 0x71180, which triggers an "Unclaimed register" error. I didn't investigate this deeply, so I don't have a suggestion for a solution. I can reproduce these errors 100% of the time. > > [1] > http://lists.freedesktop.org/archives/intel-gfx/2014-April/044179.html > > Daniel Vetter (17): > drm/i915: Check hw state in assert_can_disable_lcpll > drm/i915: Remove spll_refcount for hsw > drm/i915: Clean up WRPLL/SPLL #defines > drm/i915: Move the SPLL enabling into hsw_crt_pre_enable > drm/i915: Move SPLL disabling into hsw_crt_post_disable > drm/i915: Add a debugfs file for the shared dpll state > drm/i915: Move ddi_pll_sel into the pipe config > drm/i915: State readout and cross-checking for ddi_pll_sel > drm/i915: Precompute static ddi_pll_sel values in encoders > drm/i915: Basic shared dpll support for WRPLLs > drm/i915: Document that the pll->mode_set hook is optional > drm/i915: State readout support for WRPLLs > drm/i915: ->disable hook for WRPLLs > drm/i915: ->enable hook for WRPLLs > drm/i915: Switch to common shared dpll framework for WRPLLs > drm/i915: Only touch WRPLL hw state in enable/disable hooks > drm/i915: ddi: enable runtime pm during dpms > > Imre Deak (2): > drm/i915: ddi: move pch setup after encoder->pre_enable > drm/i915: ddi: move pch cleanup before encoder->post_disable > > drivers/gpu/drm/i915/i915_debugfs.c | 27 +++ > drivers/gpu/drm/i915/i915_drv.h | 16 +- > drivers/gpu/drm/i915/i915_reg.h | 10 +- > drivers/gpu/drm/i915/intel_crt.c | 32 +++- > drivers/gpu/drm/i915/intel_ddi.c | 340 +++++++---------------------------- > drivers/gpu/drm/i915/intel_display.c | 157 +++++++++------- > drivers/gpu/drm/i915/intel_dp.c | 23 ++- > drivers/gpu/drm/i915/intel_drv.h | 14 +- > 8 files changed, 258 insertions(+), 361 deletions(-) > > -- > 1.8.4 > > _______________________________________________ > Intel-gfx mailing list > Intel-gfx@xxxxxxxxxxxxxxxxxxxxx > http://lists.freedesktop.org/mailman/listinfo/intel-gfx -- Paulo Zanoni _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
