Inform 8bpp capability on 8bpp framebuffer in WSDISPLAYIO_GETSUPPORTEDDEPTH ioctl. This is needed to use recent updated wsfb(4) driver in 8bpp mode. We can use 1bpp X server on 8bpp framebuffer by 'startx -- -depth 1'. Tested by me. |

cpu_idle_{enter,leave} are no-ops on riscv64, so just #define away the calls ok jca@ |

Remove the P_WSLEEP specific KASSERT(). Not only procs in state SSTOP can be added to the run queue but also procs in state SRUN. The latter happens when schedcpu() kicks in before the proc had a chance to run. Problem spotted by gkoehler@ OK cheloha@ |

hardclock(9): move setitimer(2) code into itimer_update() - Move the setitimer(2) code responsible for updating the ITIMER_VIRTUAL and ITIMER_PROF timers from hardclock(9) into a new clock interrupt routine, itimer_update(). itimer_update() is periodic and runs at the same frequency as the hardclock. + Revise itimerdecr() to run within itimer_mtx instead of entering and leaving it. - Each schedstate_percpu has its own itimer_update() handle, spc_itimer. A new scheduler flag, SPCF_ITIMER, indicates whether spc_itimer was started during the last mi_switch() and needs to be stopped during the next mi_switch() or sched_exit(). - A new per-process flag, PS_ITIMER, indicates whether ITIMER_VIRTUAL and/or ITIMER_PROF are running. Checking the flag is easier than entering itimer_mtx to check process.ps_timer[]. The flag is set and cleared in a new helper function, process_reset_itimer_flag(). - In setitimer(), call need_resched() when the state of ITIMER_VIRTUAL or ITIMER_PROF is changed to force an mi_switch() and update spc_itimer. claudio@ notes that ITIMER_PROF could be implemented as a high-res timer using the thread's execution time as a guide for when to interrupt the process and assert SIGPROF. This would probably work really well in single-threaded processes. ITIMER_VIRTUAL would be more difficult to make high-res, though, as you need to exclude time spent in the kernel. Tested on powerpc64 by gkoehler@. With input from claudio@. Thread: https://marc.info/?l=openbsd-tech&m=169038818517101&w=2 ok claudio@ |
