Hi Juri, thanks for sharing the v2 patchset! In the next days I'll have a look at it, and try some tests... In the meanwhile, I have some questions/comments after a first quick look. If I understand well, the patchset does not apply deadline servers to FIFO and RR tasks, right? How does this

[RFC PATCH v2 0/6] SCHED_DEADLINE server infrastructure

2020-08-07 Thread Juri Lelli
Hi, This is RFC v2 of Peter's SCHED_DEADLINE server infrastructure implementation [1]. SCHED_DEADLINE servers can help fixing starvation issues of low priority tasks (e.g., SCHED_OTHER) when higher priority tasks monopolize CPU cycles. Today we have RT Throttling; DEADLINE servers should be able
