drm: Fix PANEL_ORIENTATION_QUIRKS breaking the Kconfig DRM menuconfig

2018-01-17T09:10:18+00:00

All Kconfig menu menu entries should have a depends on MENU_OPTION, the menu stops after the first Kconfig entry without this depends on. Since the PANEL_ORIENTATION_QUIRKS option is also used outside of DRM, it deliberately does not have a depends on DRM, but this causes all items after it to show as separate items rather then under the DRM menuconfig. This commit moves PANEL_ORIENTATION_QUIRKS to the end of the drm Kconfig file, grouping it with DRM_LIB_RANDOM which also does not depend on DRM, fixing the DRM menuconfig.

drm: move amd_gpu_scheduler into common location

2017-12-07T16:51:56+00:00

This moves and renames the AMDGPU scheduler to a common location in DRM in order to facilitate re-use by other drivers. This is mostly a straight forward rename with no code changes. One notable exception is the function to_drm_sched_fence(), which is no longer a inline header function to avoid the need to export the drm_sched_fence_ops_scheduled and drm_sched_fence_ops_finished structures.

drm: Add support for a panel-orientation connector property, v6

2017-12-04T22:03:21+00:00

On some devices the LCD panel is mounted in the casing in such a way that the up/top side of the panel does not match with the top side of the device (e.g. it is mounted upside-down). This commit adds the necessary infra for lcd-panel drm_connector-s to have a "panel orientation" property to communicate how the panel is orientated vs the casing. Userspace can use this property to check for non-normal orientation and then adjust the displayed image accordingly by rotating it to compensate. Changes in v2: -Store panel_orientation in drm_display_info, so that drm_fb_helper.c can access it easily -Have a single drm_connector_init_panel_orientation_property rather then create and attach functions. The caller is expected to set drm_display_info.panel_orientation before calling this, then this will check for platform specific quirks overriding the panel_orientation and if the panel_orientation is set after this then it will attach the property. Changes in v6: -Use an enum (with kerneldoc) rather then #defines for DRM_MODE_PANEL_ORIENTATION_* Reviewed-by: Daniel Vetter Signed-off-by: Hans de Goede Link: https://patchwork.freedesktop.org/patch/msgid/20171125193553.23986-4-hdegoede@redhat.com

drm: Add panel orientation quirks, v6.

2017-12-04T22:03:21+00:00

Some x86 clamshell design devices use portrait tablet screens and a display engine which cannot rotate in hardware, so the firmware just leaves things as is and we cannot figure out that the display is oriented non upright from the hardware. So at least on x86, we need a quirk table for this. This commit adds a DMI based quirk table which is initially populated with 5 such devices: Asus T100HA, GPD Pocket, GPD win, I.T.Works TW891 and the VIOS LTH17. This quirk table will be used by the drm code to let userspace know that the display is not mounted upright inside the devices case through a new panel orientation drm-connector property, as well as to tell fbcon to rotate the console so that it shows the right way up. Changes in v5: -Add a kernel-doc comment documenting drm_get_panel_orientation_quirk() -Remove board_* matches from the dmi-matches for the VIOS LTH17 laptop, keeping only the (identical) sys_vendor and product_name matches. This is necessary because an older version of the bios has board_vendor set to VOIS instead of VIOS Changes in v6: -Add reference to added kernel-docs in Documentation/gpu/drm-kms-helpers.rst Reviewed-by: Daniel Vetter Signed-off-by: Hans de Goede Link: https://patchwork.freedesktop.org/patch/msgid/20171125193553.23986-3-hdegoede@redhat.com

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
