| |
This is the V3 version of a series that introduces the writeback support to vkms. As a result of the previous review, this patchset can be seen in three parts: make vkms able to support multiple connector, pre-work for vkms, and the vkms implementation. Follows the details:
* First part: The first patch of this series is a fix that enables vkms to accept new connectors, such as writeback connector.
* Second part: The second part of this patchset starts on patch 02 and finish on patch 04; basically it is a pre-work that aims to make vkms composer operations a little bit more generic. These patches update the CRC files and function to make it work as a composer; it also centralizes the vkms framebuffer operations. Additionally, these changes enable the composer to use the writeback framebuffer instead of creating a copy.
* Third part: The final patch enables the support for writeback in vkms.
With this patchset, vkms can successfully pass all the kms_writeback tests from IGT.
Note: Most of the changes in the V3 was suggested by Daniel Vetter as can be seen at the link https://patchwork.freedesktop.org/patch/311844/?series=61738&rev=2
Note: This patchset depends on Daniel's rework of CRC, see it at https://patchwork.freedesktop.org/series/61737/
