drm/amdgpu: Track pending retry faults in IH and VM (v2)

2017-09-26T18:53:20+00:00

IH tracks pending retry faults in a hash table for fast lookup in interrupt context. Each VM has a short FIFO of pending VM faults for processing in a bottom half. The IH prescreening stage adds retry faults and filters out repeated retry interrupts to minimize the impact of interrupt storms. It's the VM's responsibility remove pending faults once they are handled. For now this is only done when the VM is destroyed. v2: - Made the hash table smaller and the FIFO longer. I never want the FIFO to fill up, because that would make prescreen take longer. 128 pending page faults should be enough to keep migrations busy.

drm/amd: Closed hash table with low overhead (v2)

2017-09-26T18:53:19+00:00

This adds a statically sized closed hash table implementation with low memory and CPU overhead. The API is inspired by kfifo. Storing, retrieving and deleting data does not involve any dynamic memory management, which makes it ideal for use in interrupt context. Static memory usage per entry comprises a 32 or 64 bit hash key, two bits for occupancy tracking and the value size stored in the table. No list heads or pointers are needed. Therefore this data structure should be quite cache-friendly, too. It uses linear probing and lazy deletion. During lookups free space is reclaimed and entries relocated to speed up future lookups. v2: squash in do_div and _BITOPS_LONG_SHIFT fixes Signed-off-by: Felix Kuehling Acked-by: Christian König Acked-by: Alex Deucher Signed-off-by: Alex Deucher

drm: handle override and firmware EDID at drm_do_get_edid() level

2017-09-19T14:49:25+00:00

Handle debugfs override edid and firmware edid at the low level to transparently and completely replace the real edid. Previously, we practically only used the modes from the override EDID, and none of the other data, such as audio parameters. This change also prevents actual EDID reads when the EDID is to be overridden, but retains the DDC probe. This is useful if the reason for preferring override EDID are problems with reading the data, or corruption of the data. Move firmware EDID loading from helper to core, as the functionality moves to lower level as well. This will result in a change of module parameter from drm_kms_helper.edid_firmware to drm.edid_firmware, which arguably makes more sense anyway. Some future work remains related to override and firmware EDID validation. Like before, no validation is done for override EDID. The firmware EDID is validated separately in the loader. Some unification and deduplication would be in order, to validate all of them at the drm_do_get_edid() level, like "real" EDIDs. v2: move firmware loading to core v3: rebase, commit message refresh Cc: Abdiel Janulgue Cc: Daniel Vetter Cc: Ville Syrjälä Tested-by: Abdiel Janulgue Reviewed-by: Ville Syrjälä Acked-by: Dave Airlie Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/1e8a710bcac46e5136c1a7b430074893c81f364a.1505203831.git.jani.nikula@intel.com

drm/tve200: Add new driver for TVE200

2017-08-23T21:08:36+00:00

This adds a new DRM driver for the Faraday Technology TVE200 block. This "TV Encoder" encodes a ITU-T BT.656 stream and can be found in the StorLink SL3516 (later Cortina Systems CS3516) as well as the Grain Media GM8180. I do not have definitive word from anyone at Faraday that this IP block is theirs, but it bears the hallmark of their 3-digit version code (200) and is used in two SoCs from completely different companies. (Grain Media was fully owned by Faraday until it was transferred to NovoTek this january, and Faraday did lots of work on the StorLink SoCs.) The D-Link DIR-685 uses this in connection with the Ilitek ILI9322 panel driver that supports BT.656 input, while the GM8180 apparently has been used with the Cirrus Logic CS4954 digital video encoder. The oldest user seems to be something called Techwall 2835. This driver is heavily inspired by Eric Anholt's PL111 driver and therefore I have mentioned all the ancestor authors in the header file.

drm/pl111: Initial drm/kms driver for pl111

2017-05-08T19:24:06+00:00

This is a modesetting driver for the pl111 CLCD display controller found on various ARM platforms such as the Versatile Express. The driver has only been tested on the bcm911360_entphn platform so far, with PRIME-based buffer sharing between vc4 and clcd. It reuses the existing devicetree binding, while not using quite as many of its properties as the fbdev driver does (those are left for future work). v2: Nearly complete rewrite by anholt, cutting 2/3 of the code thanks to DRM core's excellent new helpers. v3: Don't match pl110 any more, don't attach if we don't have a DRM panel, use DRM_GEM_CMA_FOPS, update MAINTAINERS, use the simple display helper, use drm_gem_cma_dumb_create (same as our wrapper). v4: Change the driver's .name to not clash with fbdev in sysfs, drop platform alias, drop redundant "drm" in DRM driver name, hook up .prepare_fb to the CMA helper so that DMA fences should work. v5: Move register definitions inside the driver directory, fix build in COMPILE_TEST and !AMBA mode. v6: Drop TIM2_CLKSEL for now to be consistent with existing DT bindings, switch back to external register definitions.

drm/fb-helper: Add multi buffer support for cma fbdev

2017-02-26T21:11:37+00:00

This patch add a config to support to create multi buffer for cma fbdev. Such as double buffer and triple buffer. Cma fbdev is convient to add a legency fbdev. And still many Android devices use fbdev now and at least double buffer is needed for these Android devices, so that a buffer flip can be operated. It will need some time for Android device vendors to abondon legency fbdev. So multi buffer for fbdev is needed.
