drm/udl: Use GEM vmap/mmap function from SHMEM helpers

2020-06-10T08:17:21Z

The udl driver contains an implementation of GEM vmap and mmap operations that is identical to the common SHMEM helper; except that udl's code uses cached pages by default. Convert udl to regular SHMEM helper functions. There's no reason to have udl behave differently from all other SHMEM drivers. The udl driver uses the SHMEM helper to enable caching. v3: * rebased onto Daniel's shmem untangle series v2: * implement .gem_create_object with SHMEM helper Signed-off-by: Thomas Zimmermann Reviewed-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20200609090820.20256-3-tzimmermann@suse.de

drm/udl: Convert to struct drm_simple_display_pipe

2019-12-11T16:02:16Z

Udl has a single display pipeline with a primary plane; perfect for simple-pipe helpers. Convert it over. The old encoder and CRTC code becomes unused and obsolete. Exported formats for the primary plane are RGB565 and XRGB8888, with the latter being emulated. The 16-bit format is the default and what is used when communicating with the device. This patch enables atomic modesetting for udl devices. v3: * remove unused field crtc from struct udl_device * set crtc_state->no_vblank at beginning of enable() v2: * move suspend/resume changes into separate patch * remove non-atomic code Signed-off-by: Thomas Zimmermann Reviewed-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20191210084905.5570-3-tzimmermann@suse.de

drm/udl: add support to export a handle to a FD on UDL.

Only importing an FD to a handle is currently supported on UDL, but the exporting functionality is equally useful. Signed-off-by: Haixia Shi Reviewed-by: Stéphane Marchesin Signed-off-by: Dave Airlie

drm/udl: initial UDL driver (v4)

2012-03-15T13:35:34Z

This is an initial drm/kms driver for the displaylink devices. Supports fb_defio, supports KMS dumb interface supports 24bpp via conversion to 16bpp, hw can do this better. supports hot unplug using new drm core features. On an unplug, it disables connector polling, unplugs connectors from sysfs, unplugs fbdev layer (using Kay's API), drops all the USB device URBs, and call the drm core to unplug the device. This driver is based in large parts on udlfb.c so I've licensed it under GPLv2. Signed-off-by: Dave Airlie
