DESCRIPTION:Speakers: Iago Toral (Igalia\, S.L.)\, Juan A. Suarez (Igalia\
 , S.L.)\, Maíra Canal (Igalia)\nThis talk will discuss various on-going e
 fforts in the driver stack for Raspberry Pi 4. Particularly:\n\n**OpenGL 3
 .x on Raspberry Pi 4 (v3d)**\n\nThe Raspberry Pi 4 isn’t capable of Open
 GL 3 but it can implement a large part of it\, sufficient to enable many a
 pplications to work on the platform. We will discuss the major limitations
  of the hardware platform for this and what we are doing to close the gap 
 as much as we can.\n\n**Improvements to CPU job handling in the Vulkan dri
 ver (v3dv)**\n\nAt XDC 2022 we discussed that one of the pain points in th
 e driver was the need to execute some parts of the command buffer in the C
 PU\, for things the GPU can’t do\, which required user-space flushes/sta
 lls and caused a number of issues. Here we will discuss some of the work w
 e have been doing to improve this situation using a combination of compute
  shaders and a new CPU kernel queue.\n\n**Global GPU stats**\n\nWe will di
 scuss our efforts to obtain global GPU usage stats from the kernel and on-
 going efforts in DRM to provide a cross-platform solution.\n\nhttps://indi
