[PATCH 1/2] mm: cma: export functions to get CMA base and size
by Lucas Stach 03 May '21

03 May '21

Make them usable in modules. Some drivers want to know where their device CMA area is located to make better decisions about the DMA programming.

[PATCH] drm/panel: xinpeng: Fix an error handling path
by Christophe JAILLET 01 May '21

'ret' is know to be >=0 a this point. Checking the return value of 'mipi_dsi_dcs_enter_sleep_mode()' was intended instead. So add the missing assignment.

[RFC PATCH 00/17] CRIU support for ROCm
by Felix Kuehling 01 May '21

01 May '21

This patch series is a prototype for supporting CRIU for ROCm applications. More work is needed before this can be upstreamed and released, including a new ioctl API that is extensible without breaking the ABI. The user mode code to go with this can be found at https://github.com/RadeonOpenCompute/criu/tree/criu-dev/test/others/ext-kfd It will be discussed with the CRIU community on criu(a)openvz.org and evolve together with this patch series.
