2022-07-14Replace tabs by spaces after "#define". No functional changes, justVitaliy Makkoveev
prevent future diffs to be ugly. ok bluhm@
2022-07-13Implement the fundamentals for suspend/resume on arm64. This uses PSCIMark Kettenis
to turn off the secondary CPUs and suspend the primary CPU using the CPU_OFF and SYSTEM_SUSPEND calls. A new "halt" IPI is added to turn off the ssecondary CPUs. This IPI is implemented for the ampintc(4) and agintc(4) interrupt controllers. Fulle suspend/resume support is only implemented for ampintc(4). This is enough to suspend and resume boards based on the Allwinner A64 SoC, provided the necessary wakeup interrupts have been set up (not part of this commit). ok patrick@

2022-07-12Add db_rint(), an MI interface to db_enter() copied from kdbrint() in vax codeJeremie Courreges-Anglas
If ddb.console is set and your serial console driver uses it, db_rint(), lets you enter ddb(4) by typing the ESC D escape sequence. This is useful for drivers like sfuart(4) where the hardware doesn't have a true BREAK mechanism. Suggested by miod@, ok kettenis@ miod@
2022-07-12Remove PIPEXCSESSION pipex(4) ioctl(2) command from kernel and man page.Vitaliy Makkoveev
Long time ago pipex(4) session can't be deleted until both pipex(4) input and output queues become empty. Dead sessions were linked to the stack and the `ip_forward' flag was used to prevent packets forwarding. npppd(8) marked such sessions by doing PIPEXCSESSION ioctl(2) call. But since we started to unlink close session from the stack, this logic became unnecessary. Also pipex(4) session could be closed just after close request. npppd(8) was the only userland program which did PIPEXCSESSION ioctl(2) call, and we removed it week ago. It's time to remove the remains. Now the `flags' member of 'pipex_session' structure became immutable. ok yasuoka@

2022-07-11Simplify the aiodone daemon which is only used for async writes.Martin Pieuchot
- Remove unused support for asynchronous read, including error conditions - Grab the proper lock for each page that has been written to swap. This allows to enable an assertion in uvm_page_unbusy(). - Move the uvm_anon_release() call outside of uvm_page_unbusy() and assert for the different anon cases. ok beck@, kettenis@
2022-07-11Remove asynchronous read support in uvm_swap_get().Martin Pieuchot
Reading pages from swap is always done synchronously. The fault handler needs to sleep and PGO_SYNCIO is already asserted a couple of lines above. ok beck@, kettenis@ as part of a larger diff.

1000 to pass the rate to amptimer_set_clockrate(). Fixes the system clock running too slow for ntpd to keep in sync. ok patrick@
2022-07-10Add missing `pipex_list_mtx' mutex(9) around all sessions loop withinVitaliy Makkoveev
pipex_ip_output(). The all sessions loop was reworked to make possible to drop the lock within. ok bluhm@ yasuoka@.
2022-07-10if_detach() should wait until concurrent (*if_qstart)() interface startVitaliy Makkoveev
routines finished. Call ifq_barrier(9) just after we unlinked dying interface from the stack. From this point it is not accessible by if_get(9) and if_unit(9), and all concurrent threads owning interface pointer finished. It also detached from pseudo drivers like bridge(4). We only could have concurrent (*if_qstart)() handlers running, so wait them and then continue destruction. Reported and tested by Hrvoje Popovski. ok bluhm@

2022-07-09Consistently use uint64_t.Mark Kettenis
2022-07-08Display parameters exposed to userland as percentages (backlight, brightness,Miod Vallat
contrast) are not valid if they only have one state, i.e. minimum and maximum values being equal. Do not expose them to userland in this case, for wsconsctl would attempt to divide by zero (which is known to have unwelcome consequences). This allows display drivers trusting not-so-reliable sources (fdt, bogus hardware...) to not have to perform those checks themselves. Found the hard way by daniel@. No firm consensus on this workaround, using one seniority point here, will revert if this spawns complaints.

2022-07-07Revert previous attempt at serializing `uo_refs'.Martin Pieuchot
It is incorrect to look at/modify `uo_refs' without lock in uvm_vnp_sync(). However sleeping is not possible and spinning introduces a deadlock with the KERNEL_LOCK() when another thread faults on a mmaped region related to a vnode we're currently synching. A proper fix should be investigated. For now a kown a race, mostly safe due to the KERNEL_LOCK(), is better than a possible deadlock. Issue reported by caspar@ Discussed with and ok semarie@
2022-07-07remove a DPRINTF() from iwm(4) which no longer makes any senseStefan Sperling
The conditions under which this debug message should trigger were changed in r1.330 (cvs commit RcatFKLXoHUopLvW), which removed a txd_done() call located before txq_advance(). The mbuf for the most recently completed frame will no longer be NULL on entry. Prompted by a question from waddlesplash at haiku-os.
2022-07-07retire NexGen CPU identification codeDaniel Dickman
On OpenBSD/i386 we only support Pentium compatible CPUs with an FPU. The NexGen CPUs probably don't meet this requirement so remove the small amount of support code to identify this brand of CPU. The Nx586 "P" models did not include an FPU as they were expected to be paired with an Nx587 FPU (which was never officially released). The Nx586 "FP" models did include an FPU, but even these are allegedly 386 clones and not Pentium compatible. According to some websites, 486 instructions were emulated via hypercode. However the 486 instruction emulation was only enough to run applications and wasn't good enough to run an OS that needs newer 486 and Pentium instructions. Finally, while our current code references the "Processor Recognition Application Note", we only implement the half of the documented algorithm to detect NexGen CPUs. We don't implement the second half of the algorithm to check for the vendor string "NexGenDriven" on NexGen CPUs that support the CPUID instruction (like the Nx586-P120 and Nx586-P133). ok jsg@

2022-07-05workaround link training problems on s3 resume with alder lakeJonathan Gray
The firmware from multiple lenovo alder lake machines claim there are two eDP ports in the video bios table (VBT). Which results in link training problems on resume from S3 with the screen continually turning on and off. Forcing port B to not be recognised as eDP works around this. I believe port A is the normal eDP port. https://gitlab.freedesktop.org/drm/intel/-/issues/5531 https://gitlab.freedesktop.org/drm/intel/-/issues/4950
