2016-10-18drm: Centralize format informationLaurent Pinchart1-0/+84
Various pieces of information about DRM formats (number of planes, color depth, chroma subsampling, ...) are scattered across different helper functions in the DRM core. Callers of those functions often need to access more than a single parameter of the format, leading to inefficiencies due to multiple lookups. Centralize all format information in a data structure and create a function to look up information based on the format 4CC.

2016-10-18drm/i915: Add lspcon resume functionShashank Sharma3-1/+15
As per the software design, we are driving lspcon in PCON mode. But while resuming from suspend, lspcon can go in LS mode (which is its default operating mode on power on) This patch adds a resume function for lspcon, which makes sure its operating in PCON mode, post resume.

2016-10-18drm/i915: Parse VBT data for lspconShashank Sharma2-0/+54
Many GEN9 boards come with on-board lspcon cards. Fot these boards, VBT configuration should properly point out if a particular port contains lspcon device, so that driver can initialize it properly.

2016-10-18drm: Helper for lspcon in drm_dp_dual_modeShashank Sharma1-0/+103
This patch adds lspcon support in dp_dual_mode helper. lspcon is essentially a dp->hdmi dongle with dual personality. LS mode: It works as a passive dongle, by level shifting DP++ signals to HDMI signals, in LS mode. PCON mode: It works as a protocol converter active dongle in pcon mode, by converting DP++ outputs to HDMI 2.0 outputs. This patch adds support for lspcon detection and mode set switch operations, as a dp dual mode dongle. v2: Addressed review comments from Ville - add adaptor id for lspcon devices (0x08), use it to identify lspcon - change function names old: drm_lspcon_get_current_mode/drm_lspcon_change_mode new: drm_lspcon_get_mode/drm_lspcon_set_mode - change drm_lspcon_get_mode type to int, to match drm_dp_dual_mode_get_tmds_output - change 'err' to 'ret' to match the rest of the functions - remove pointless typecasting during call to dual_mode_read - fix the but while setting value of data, while writing lspcon mode - fix indentation - change mdelay(10) -> msleep(10) - return ETIMEDOUT instead of EFAULT, when lspcon mode change times out - Add an empty line to separate std regs macros and lspcon regs macros Indent bit definition v3: Addressed review comments from Rodrigo - change macro name from DP_DUAL_MODE_TYPE_LSPCON to DP_DUAL_MODE_TYPE_HAS_DPCD for better readability - change macro name from DP_DUAL_MODE_LSPCON_MODE_PCON to DP_DUAL_MODE_LSPCON_MODE_PCON for better readability - add comment for MCA specific offsets like 0x40 and 0x41 - remove DP_DUAL_MODE_REV_TYPE2 check while checking lspcon adapter id v4: Addressed review comments from Ville - Fixed indentation at few places - s/current_mode/mode - s/reqd_mode/mode - remove unnecessary void* cast - remove drm_edid.h from includes - Add a comment for _HAS_DPCD - Fix enum description, for lspcon_mode. v5: Rebase v6: Rebase Signed-off-by: Shashank Sharma <shashank.sharma@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Acked-by: Dave Airlie <airlied@gmail.com> Acked-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1476720277-16298-1-git-send-email-shashank.sharma@intel.com

Before accessing the u/v offset(aka, u/vbo for IPUv3) of the old plane state's relevant fb, we should make sure the fb is in YU12 or YV12 pixel format(which are the two YUV pixel formats we support only), otherwise, we are likely to trigger BUG_ON() in drm_plane_state_to_u/vbo() since the fb's pixel format is probably not YU12 or YV12.

2016-10-17drm: Add API for capturing frame CRCsTomeu Vizoso5-3/+435
Adds files and directories to debugfs for controlling and reading frame CRCs, per CRTC: dri/0/crtc-0/crc dri/0/crtc-0/crc/control dri/0/crtc-0/crc/data Drivers can implement the set_crc_source callback() in drm_crtc_funcs to start and stop generating frame CRCs and can add entries to the output by calling drm_crtc_add_crc_entry. v2: - Lots of good fixes suggested by Thierry. - Added documentation. - Changed the debugfs layout. - Moved to allocate the entries circular queue once when frame generation gets enabled for the first time. v3: - Use the control file just to select the source, and start and stop capture when the data file is opened and closed, respectively. - Make variable the number of CRC values per entry, per source. - Allocate entries queue each time we start capturing as now there isn't a fixed number of CRC values per entry. - Store the frame counter in the data file as a 8-digit hex number. - For sources that cannot provide useful frame numbers, place XXXXXXXX in the frame field. v4: - Build only if CONFIG_DEBUG_FS is enabled. - Use memdup_user_nul. - Consolidate calculation of the size of an entry in a helper. - Add 0x prefix to hex numbers in the data file. - Remove unnecessary snprintf and strlen usage in read callback. v5: - Made the crcs array in drm_crtc_crc_entry fixed-size - Lots of other smaller improvements suggested by Emil Velikov v7: - Move definition of drm_debugfs_crtc_crc_add to drm_internal.h v8: - Call debugfs_remove_recursive when we fail to create the minor device v9: - Register the debugfs directory for a crtc from drm_crtc_register_all() v10: - Don't let debugfs failures interrupt CRTC registration (Emil Velikov) v11: - Remove extra brace that broke compilation.

2016-10-16drm/i915/gen9: Make skl_wm_level per-planeLyude3-108/+110
Having skl_wm_level contain all of the watermarks for each plane is annoying since it prevents us from having any sort of object to represent a single watermark level, something we take advantage of in the next commit to cut down on all of the copy paste code in here.

2016-10-14drm/i915/gtt: Free unused lower-level page tablesMichał Winiarski1-8/+73
Since "Dynamic page table allocations" were introduced, our page tables can grow (being dynamically allocated) with address space range usage. Unfortunately, their lifetime is bound to vm. This is not a huge problem when we're not using softpin - drm_mm is creating an upper bound on used range by causing addresses for our VMAs to eventually be reused. With softpin, long lived contexts can drain the system out of memory even with a single "small" object. For example: bo = bo_alloc(size); while(true) offset += size; exec(bo, offset); Will cause us to create new allocations until all memory in the system is used for tracking GPU pages (even though almost all PTEs in this vm are pointing to scratch). Let's free unused page tables in clear_range to prevent this - if no entries are used, we can safely free it and return this information to the caller (so that higher-level entry is pointing to scratch). v2: Document return value and free semantics (Joonas) v3: No newlines in vars block (Joonas) v4: Drop redundant local 'reduce' variable v5: Handle CI fail with enable_ppgtt=2 Cc: Michel Thierry <michel.thierry@intel.com> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by: Michał Winiarski <michal.winiarski@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: http://patchwork.freedesktop.org/patch/msgid/1476360162-24062-3-git-send-email-michal.winiarski@intel.com

Let's use more top-down approach, where each gen8_ppgtt_clear_* function is responsible for clearing the struct passed as an argument and calling relevant clear_range functions on lower-level tables. Doing this rather than operating on PTE ranges makes the implementation of shrinking page tables quite simple. v2: Drop min when calculating num_entries, no negation in 48b ppgtt check, no newlines in vars block (Joonas) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Michel Thierry <michel.thierry@intel.com> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Signed-off-by: Michał Winiarski <michal.winiarski@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: http://patchwork.freedesktop.org/patch/msgid/1476360162-24062-2-git-send-email-michal.winiarski@intel.com

2016-10-14drm/i915: Fix mismatched INIT power domain disabling during suspendImre Deak1-2/+2
Currently the display INIT power domain disabling/enabling happens in a mismatched way in the suspend/resume_early hooks respectively. This can leave display power wells incorrectly disabled in the resume hook if the suspend sequence is aborted for some reason resulting in the suspend/resume hooks getting called but the suspend_late/resume_early hooks being skipped. In particular this change fixes "Unclaimed read from register 0x1e1204" on BYT/BSW triggered from i915_drm_resume()-> intel_pps_unlock_regs_wa() when suspending with /sys/power/pm_test set to devices.
