2018-07-03locking: Implement an algorithm choice for Wound-Wait mutexesThomas Hellstrom1-1/+1
The current Wound-Wait mutex algorithm is actually not Wound-Wait but Wait-Die. Implement also Wound-Wait as a per-ww-class choice. Wound-Wait is, contrary to Wait-Die a preemptive algorithm and is known to generate fewer backoffs. Testing reveals that this is true if the number of simultaneous contending transactions is small. As the number of simultaneous contending threads increases, Wait-Wound becomes inferior to Wait-Die in terms of elapsed time. Possibly due to the larger number of held locks of sleeping transactions. Update documentation and callers. Timings using git://people.freedesktop.org/~thomash/ww_mutex_test tag patch-18-06-15 Each thread runs 100000 batches of lock / unlock 800 ww mutexes randomly chosen out of 100000.

2018-07-03drm: add missing ctx argument to plane transitional helpersRussell King10-11/+15
In commits: 34a2ab5e0689 ("drm: Add acquire ctx parameter to ->update_plane") 1931529448bc ("drm: Add acquire ctx parameter to ->plane_disable") a pointer to a drm_modeset_acquire_ctx structure was added as an argument to the method prototypes. The transitional helpers are supposed to be directly plugged in as implementations of these methods, but doing so generates a warning. Add the missing argument. A number of buggy users were added for drm_plane_helper_disable() which need to be fixed up for this change, which we do by passing a NULL ctx argument.

2018-07-01drm/pl111: Support Nomadik LCDC variantLinus Walleij6-13/+145
The Nomadik has a variant of the PL110 known as "Color LCD Controller" LCDC. This variant has the same bit ordering as the DRM subsystem (in difference from the other variants) and adds a few bits for the control of 5551, 565 etc in the control register. Notably it also adds a packed RGB888 24BPP mode. We add support by detecting this variant and also adding a small plug-in that will mux the LCDC out if the ASIC happens to be muxed to the other graphics controller (they are mutually exclusive).

Pull block fixes from Jens Axboe: "Small set of fixes for this series. Mostly just minor fixes, the only oddball in here is the sg change. The sg change came out of the stall fix for NVMe, where we added a mempool and limited us to a single page allocation. CONFIG_SG_DEBUG sort-of ruins that, since we'd need to account for that. That's actually a generic problem, since lots of drivers need to allocate SG lists. So this just removes support for CONFIG_SG_DEBUG, which I added back in 2007 and to my knowledge it was never useful.

Description of DRA7 Errata i932: In rare circumstances DPLL_VIDEO1 and DPLL_VIDEO2 PLL's may not lock on the first attempt during DSS initialization. When this occurs, a subsequent attempt to relock the PLL will result in PLL successfully locking. This patch does the following as per the errata recommendation: - retries locking the PLL upto 20 times. - The time to wait for a PLL lock set to 1000 REFCLK cycles. We use usleep_range to wait for 1000 REFCLK cycles in the us range. This tight constraint is imposed as a lock later than 1000 REFCLK cycles may have high jitter. - Criteria for PLL lock is extended from check on just the PLL_LOCK bit to check on 6 PLL_STATUS bits. Silicon Versions Impacted: DRA71, DRA72, DRA74, DRA76 - All silicon revisions AM57x - All silicon revisions OMAP4/5 are not impacted by this errata Signed-off-by: Venkateswara Rao Mandela <[email protected]> [[email protected]: ported to v4.14] Signed-off-by: Tomi Valkeinen <[email protected]>

As well many other fix and improvements, Including: - Use GEM suspend when aborting initialization (Chris) - Change i915_gem_fault to return vm_fault_t (Chris) - Expand VMA to Non gem object entities (Chris) - Improve logs for load failure, but quite logging on fault injection to avoid noise on CI (Chris) - Other page directory handling fixes and improvements for gen6 (Chris) - Other gtt clean-up removing redundancies and unused checks (Chris) - Reorder aliasing ppgtt fini (Chris) - Refactor of unsetting obg->mm.pages (Chris) - Apply batch location restrictions before pinning (Chris) - Ringbuffer fixes for context restore (Chris) - Execlist fixes on freeing error pointer on allocation error (Chris) - Make closing request flush mandatory (Chris) - Move GEM sanitize from resume_early to resume (Chris) - Improve debug dumps (Chris) - Silent compiler for selftest (Chris) - Other execlists changes to improve hangcheck and reset. - Many gtt page directory fixes and improvements (Chris) - Reorg context workarounds (Chris) - Avoid ERR_PTR dereference on selftest (Chris) Other GEM related work: - Stop trying to reset GPU if reset failed (Mika) - Add HW workaround for KBL to fix GPU reset (Mika) - Fix context ban and hang accounting for client (Mika) - Fixes on OA perf (Michel, Jani) - Refactor on GuC log mechanisms (Piotr) - Enable provoking vertex fix on Gen9 system (Kenneth) More ICL patches for Display enabling: - ICL - 10-bit support for HDMI (RK) - ICL - Start adding TBT PLL (Paulo) - ICL - DDI HDMK level selection (Manasi) - ICL - GMBUS GPIO pin mapping fix (Mahesh) - ICL - Adding DP_AUX_E support (James) - ICL - Display interrupts handling (DK) Other display fixes and improvements: - Fix sprite destination color keying on SKL+ (Ville) - Fixes and improvements on PCH detection, specially for non PCH systems (Jani) - Document PCH_NOP (Lucas) - Allow DBLSCAN user modes with eDP/LVDS/DSI (Ville) - Opregion and ACPI cleanup and organization (Jani) - Kill delays when activation psr (Rodrigo) - ...and a consequent fix of the psr activation flow (DK) - Fix HDMI infoframe setting (Imre) - Fix Display interrupts and modes on old gens (Ville) - Start switching to kernel unsigned int types (Jani) - Introduction to Amber Lake and Whiskey Lake platforms (Jose) - Audio clock fixes for HBR3 (RK) - Standardize i915_reg.h definitions according to our doc and checkpatch (Paulo) - Remove unused timespec_to_jiffies_timeout function (Arnd) - Increase the scope of PSR wake fix for other VBTs out there (Vathsala) - Improve debug msgs with prop name/id (Ville) - Other clean up on unecessary cursor size defines (Ville) - Enforce max hdisplay/hblank_start limits on HSW/BDW (Ville) - Make ELD pointers constant (Jani) - Fix for PSR VBT parse (Colin) - Add warn about unsupported CDCLK rates (Imre) Signed-off-by: Dave Airlie <[email protected]> # gpg: Signature made Thu 21 Jun 2018 07:12:10 AM AEST # gpg: using RSA key FA625F640EEB13CA # gpg: Good signature from "Rodrigo Vivi <[email protected]>" # gpg: aka "Rodrigo Vivi <[email protected]>" # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 6D20 7068 EEDD 6509 1C2C E2A3 FA62 5F64 0EEB 13CA Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2018-06-27drm/sun4i: DW HDMI: Expand algorithm for possible crtcsJernej Skrabec1-1/+45
drm_of_find_possible_crtcs() doesn't work when DW HDMI encoder is connected to TCON (crtc) through mux in TCON TOP. In that case TCON TOP HDMI mux input port has to be manually traversed and checked if it matches any known crtc.

2018-06-27drm: of: Export and rename drm_crtc_port_mask()Jernej Skrabec1-4/+5
Function is useful when drm_of_find_possible_crtcs() can't be used and custom parsing is needed. This can happen for example when there is a node with multiple muxes between crtc and encoder.

2018-06-27drm/sun4i: DW HDMI PHY: Add support for second PLLJernej Skrabec2-5/+17
Some DW HDMI PHYs, like those found in A64 and R40 SoCs, can select between two clock parents. Add code which reads second PLL from DT.

2018-06-27drm/sun4i: Don't change clock bits in DW HDMI PHY driverJernej Skrabec2-2/+12
DW HDMI PHY driver and PHY clock driver share same registers. Make sure that DW HDMI PHY setup code doesn't change any clock related bits. During initialization, set PHY PLL parent bit to 0.

2018-06-27drm/sun4i: Enable DW HDMI PHY clockJernej Skrabec1-1/+6
Current DW HDMI PHY code never prepares and enables PHY clock after it is created. It's just used as it is. This may work in some cases, but it's clearly wrong. Fix it by adding proper calls to enable/disable PHY clock.

Both mixers have similar capabilities as others SoCs with DE2. First mixer has 1 VI and 3 UI planes and supports HW scaling on all planes. Second mixer has 1 VI and 1 UI planes and also supports HW scaling on all planes.
