* drm/i915: enable scramblingShashank Sharma2017-03-281-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Geminilake platform sports a native HDMI 2.0 controller, and is capable of driving pixel-clocks upto 594Mhz. HDMI 2.0 spec mendates scrambling for these higher clocks, for reduced RF footprint. This patch checks if the monitor supports scrambling, and if required, enables it during the modeset. V2: Addressed review comments from Ville: - Do not track scrambling status in DRM layer, track somewhere in driver like in intel_crtc_state. - Don't talk to monitor at such a low layer, set monitor scrambling in intel_enable_ddi() before enabling the port. V3: Addressed review comments from Jani - In comments, function names, use "sink" instead of "monitor", so that the implementation could be close to the language of HDMI spec. V4: Addressed review comment from Maarten - scrambling -> hdmi_scrambling - high_tmds_clock_ratio -> hdmi_high_tmds_clock_ratio V5: Addressed review comments from Ville and Ander - Do not modifiy the crtc_state after compute_config. Move all scrambling and tmds_clock_ratio calcutations to compute_config. - While setting scrambling for source/sink, do not check the conditions again, just go by the crtc_state flags. This will simplyfy the condition checks. V6: Addressed review comments from Ville - Do not add IS_GLK check in disable/enable function, instead add it in compute_config, while setting state flags. - Remove unnecessary paranthesis. - Simplyfy handle_sink_scrambling function as suggested. - Add readout code for scrambling status in get_ddi_config and add a check for the same in pipe_config_compare. V7: Addressed review comments from Ander/Ville - No separate function for source scrambling, make it inline - Align the last line of the macro TRANS_DDI_HDMI_SCRAMBLING_MASK - Do not add platform check while setting source scrambling - Use pipe_config instead of crtc->config to set sink scrambling - To readout scrambling status, Compare with SCRAMBLING_MASK not any of its bits - Remove platform check in intel_pipe_config_compare while checking scrambling status V8: Fixed mege conflict, Addressed review comments from Ander - Remove the desciption/comment about scrambling fom the caller, move it to the function - Move the IS_GLK check into scrambling function - Fix alignment V9: Fixed review comments from Ville, Ander - Pass the scrambling state variables as bool input to the sink_scrambling function and let the disable call be unconditional. - Fix alignments in function calls and debug messages. - Add kernel doc for function intel_hdmi_handle_sink_scrambling V10: Rebase Signed-off-by: Shashank Sharma <shashank.sharma@intel.com> Reviewed-by: Ander Conselvan de Oliveira <conselvan2@gmail.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1489404244-16608-6-git-send-email-shashank.sharma@intel.com
* drm/i915: Use ktime to calculate rc0 residencyMika Kuoppala2017-03-161-2/+0
| | | | | | | | | | | | | | | | | | | | We have used cz timestamp register to gain a reference time wrt to residency calculations. The residency counts are in cz clk ticks (333Mhz clock) but for some reason the cz timestamp register gives 100us units. Perhaps for some other usage, the base-ten based values are easier, but in residency calculations raw units would have been the easiest. As there is not much advantage of using base-ten clock through a more costly punit access, take our reference times directly from kernel clock. v2: use ktime (Chris, Ville) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>

| | | | | | | | | | | | | | | | The REDIRECT_TO_GUC bit is a strange beast as it is a disable bit - setting the bit in the pm interrupt generation stops the interrupt going to the guc (not sending it to the guc as the name implies).

* drm/i915: Initialize pm_intr_keep during intel_irq_init for GuCSagar Arun Kamble2017-03-091-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Driver needs to ensure that it doesn't mask the PM interrupts, which are unmasked/needed by GuC firmware. For that, Driver maintains a bitmask of interrupts to be kept unmasked, pm_intr_keep. pm_intr_keep was determined across GuC load. GuC gets loaded in different scenarios and it is not going to change the pm_intr_keep so this patch moves its setup to intel_irq_init. This patch fixes incorrect RPS masking leading to UP interrupts triggered even when at cur_freq=max and inversly for Down interrupts.

If we prime the CCID/PD registers with the first request in the queue (even for the hung request), we prevent invalid memory access for the following requests (and continually hung engines). v2: Magic BIT(8), reserved for future use but still appears unused. v3: Some commentary on handling innocent vs guilty requests v4: Add a wait for PD_BASE fetch.

Nothing too major, the tinydrm and mmu-less support should make writing smaller drivers easier for some of the simpler platforms, and there are a bunch of documentation updates. Intel grew displayport MST audio support which is hopefully useful to people, and FBC is on by default for GEN9+ (so people know where to look for regressions). AMDGPU has a lot of fixes that would like new firmware files installed for some GPUs. Other than that it's pretty scattered all over. I may have a follow up pull request as I know BenH has a bunch of AST rework and fixes and I'd like to get those in once they've been tested by AST, and I've got at least one pull request I'm just trying to get the author to fix up.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following a reset, the context and page directory registers are lost. However, the queue of requests that we resubmit after the reset may depend upon them - the registers are restored from a context image, but that restore may be inhibited and may simply be absent from the request if it was in the middle of a sequence using the same context. If we prime the CCID/PD registers with the first request in the queue (even for the hung request), we prevent invalid memory access for the following requests (and continually hung engines). v2: Magic BIT(8), reserved for future use but still appears unused. v3: Some commentary on handling innocent vs guilty requests v4: Add a wait for PD_BASE fetch.

| * drm/i915: Disable L2 cache clock gating on 830 when using the overlayVille Syrjälä2016-12-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BSpec says: "Overlay Clock Gating Must be Disabled: Overlay & L2 Cache clock gating must be disabled in order to prevent device hangs when turning off overlay.SW must turn off Ovrunit clock gating (6200h) and L2 Cache clock gating (C8h)." We only turned off the overlay clock gating (due to lack of docs I presume). After a bit of experimentation it looks like the the magic C8h register lives in the PCI config space of device 0, and the magic bit appears to be bit 2. Or at the very least this eliminates the GPU death after MI_OVERLAY_OFF. L2 clock gating seems to save ~80mW, so let's keep it on unless we need to actually use the overlay. Also let's move the OVRUNIT clock gating to the same place since we can, and 845 supposedly doesn't need it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The audio chicken bit (register offset 0x62f38) seems required to make DP audio working on some machines. At least, on Dell Wyse 3040, I failed to get the audio unless this bit is set once. Strangely, the bit seems necessary only once, and it persists after that, even some power-off cycles. The register is supposedly write-only, so it's no evidence whether the bit keeps effect persistently. But, judging from the experiment, it looks enough to set it up once at the device initialization. The patch is basically a cut from the original patch by Pierre-Louis Bossart. v1->v2: drop read since it's a write-only reg.

* drm/i915/bxt: Broxton decoupled MMIOPraveen Paneri2016-11-161-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Decoupled MMIO is an alternative way to access forcewake domain registers, which requires less cycles for a single read/write and avoids frequent software forcewake. This certainly gives advantage over the forcewake as this new mechanism “decouples” CPU cycles and allow them to complete even when GT is in a CPD (frequency change) or C6 state. This can co-exist with forcewake and we will continue to use forcewake as appropriate. E.g. 64-bit register writes to avoid writing 2 dwords separately and land into funny situations. v2: - Moved platform check out of the function and got rid of duplicate functions to find out decoupled power domain (Chris) - Added a check for forcewake already held and skipped decoupled access (Chris) - Skipped writing 64 bit registers through decoupled MMIO (Chris) v3: - Improved commit message with more info on decoupled mmio (Tvrtko) - Changed decoupled operation to enum and used u32 instead of uint_32 data type for register offset (Tvrtko) - Moved HAS_DECOUPLED_MMIO to device info (Tvrtko) - Added lookup table for converting fw_engine to pd_engine (Tvrtko) - Improved __gen9_decoupled_read and __gen9_decoupled_write routines (Tvrtko) v4: - Fixed alignment and variable names (Chris) - Write GEN9_DECOUPLED_REG0_DW1 register in just one go (Zhe Wang) v5: - Changed HAS_DECOUPLED_MMIO() argument name to dev_priv (Tvrtko) - Sanitize info->had_decoupled_mmio at init (Chris) Signed-off-by: Zhe Wang <zhe1.wang@intel.com> Signed-off-by: Praveen Paneri <praveen.paneri@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1479230360-22395-1-git-send-email-praveen.paneri@intel.com
* drm/i915: Address broxton phy registers based on phy and channel numberAnder Conselvan de Oliveira2016-10-281-68/+73
| | | | | | | | | | | | | | | | | | The port registers related to the phys in broxton map to different channels and specific phys. Make that mapping explicit. v2: Pass enum dpio_phy to macros instead of mmio base. (Imre) v3: Fix typo in macros. (Imre) v4: Also change variables from u32 to enum dpio_phy. (Imre) Remove leftovers from previous version. (Imre) v5: Actually git add the changes.

* drm/i915/audio: set proper N/M in modesetLibin Yang2016-10-261-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When modeset occurs and the LS_CLK is set to some special values in DP mode, the N/M need to be set manually if audio is playing. Otherwise the first several seconds may be silent in audio playback. The relationship of Maud and Naud is expressed in the following equation: Maud/Naud = 512 * fs / f_LS_Clk Please refer VESA DisplayPort Standard spec for details. v2 by Jani: - organize Maud/Naud table according to DP 1.4 spec - add 64k and 128k audio rates - update HSW_AUD_M_CTS_ENABLE register when Maud not found - remove extra checks for port clock - simplify Maud/Naud lookup - reset patch author back to Libin Cc: "Zhang, Keqiao" <keqiao.zhang@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: "Lin, Mengdong" <mengdong.lin@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Libin Yang <libin.yang@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1477407258-30599-3-git-send-email-jani.nikula@intel.com
* drm/i915: Support for GuC interruptsSagar Arun Kamble2016-10-251-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are certain types of interrupts which Host can receive from GuC. GuC ukernel sends an interrupt to Host for certain events, like for example retrieve/consume the logs generated by ukernel. This patch adds support to receive interrupts from GuC but currently enables & partially handles only the interrupt sent by GuC ukernel. Future patches will add support for handling other interrupt types. v2: - Use common low level routines for PM IER/IIR programming (Chris) - Rename interrupt functions to gen9_xxx from gen8_xxx (Chris) - Replace disabling of wake ref asserts with rpm get/put (Chris) v3: - Update comments for more clarity. (Tvrtko) - Remove the masking of GuC interrupt, which was kept masked till the start of bottom half, its not really needed as there is only a single instance of work item & wq is ordered. (Tvrtko) v4: - Rebase. - Rename guc_events to pm_guc_events so as to be indicative of the register/control block it is associated with. (Chris) - Add handling for back to back log buffer flush interrupts. v5: - Move the read & clearing of register, containing Guc2Host message bits, outside the irq spinlock. (Tvrtko) v6: - Move the log buffer flush interrupt related stuff to the following patch so as to do only generic bits in this patch. (Tvrtko) - Rebase. v7: - Remove the interrupts_enabled check from gen9_guc_irq_handler, want to process that last interrupt also before disabling the interrupt, sync against the work queued by irq handler will be done by caller disabling the interrupt.
