From: Oleksandr Andrushchenko <oleksandr_andrushchenko@xxxxxxxx> Hello, This series contains an assorted set of fixes and improvements for the Xen para-virtualized display driver and grant device driver which I have collected over the last couple of months: 1. Minor fixes to grant device driver and drm/xen-front. 2. New format (YUYV) added to the list of the PV DRM supported formats which allows the driver to be used in zero-copying use-cases when a camera device is the source of the dma-bufs. 3. Synchronization with the latest para-virtualized protocol definition in Xen [1]. 4. SGT offset is now propagated to the backend: while importing a dmabuf it is possible that the data of the buffer is put with offset which is indicated by the SGT offset. This is needed for some GPUs which have non-zero offset. 5. Version 2 of the Xen displif protocol adds XENDISPL_OP_GET_EDID request which allows frontends to request EDID structure per connector. This request is optional and if not supported by the backend then visible area is still defined by the relevant XenStore's "resolution" property. If backend provides EDID with XENDISPL_OP_GET_EDID request then its values must take precedence over the resolutions defined in XenStore. Thank you, Oleksandr Andrushchenko [1] https://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=c27a184225eab54d20435c8cab5ad0ef384dc2c0 Oleksandr Andrushchenko (6): xen/gntdev: Fix dmabuf import with non-zero sgt offset drm/xen-front: Fix misused IS_ERR_OR_NULL checks drm/xen-front: Add YUYV to supported formats xen: Sync up with the canonical protocol definition in Xen drm/xen-front: Pass dumb buffer data offset to the backend drm/xen-front: Add support for EDID based configuration drivers/gpu/drm/xen/xen_drm_front.c | 72 +++++++++++++++- drivers/gpu/drm/xen/xen_drm_front.h | 11 ++- drivers/gpu/drm/xen/xen_drm_front_cfg.c | 82 +++++++++++++++++++ drivers/gpu/drm/xen/xen_drm_front_cfg.h | 7 ++ drivers/gpu/drm/xen/xen_drm_front_conn.c | 27 +++++- drivers/gpu/drm/xen/xen_drm_front_evtchnl.c | 3 + drivers/gpu/drm/xen/xen_drm_front_evtchnl.h | 3 + drivers/gpu/drm/xen/xen_drm_front_gem.c | 11 +-- drivers/gpu/drm/xen/xen_drm_front_kms.c | 7 +- drivers/xen/gntdev-dmabuf.c | 8 ++ include/xen/interface/io/displif.h | 91 ++++++++++++++++++++- 11 files changed, 305 insertions(+), 17 deletions(-) -- 2.17.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
