2022-08-03Add aplaudio(4) and aplmca(4). The aplmca(4) driver controls the hardwareMark Kettenis
block that takes data from apldma(4), serializes it and sends it out on the i2s ports. The aplaudio(4) driver ties together aplmca(4) and various codecs to present an audio(4) interface to the system. This is still WIP, but good enough to play back audio on the speaker in the M1 mini. ok patrick@
2022-08-03Clear active state when we attach.Mark Kettenis
ok patrick@
2022-08-03Bug was reported by Chriss Cappucio. It has turned out my earlier changeAlexandr Nedvedicky
to pf_lb.c was not complete. We must add a test to determine number of addresses defined by pool, so we don't treat pool definition 172.16.0.0/16 as a single IP address in pool. If pool is defined as 172.16.0.0/16, then we don't want to fall back to PF_POOL_NONE. Missing this measure in pf_map_addr() may cause pf_get_sport() to enter infinite loop when source ports translation become depleted for the first address found in pool (like 172.16.0.1), because the bug prevents pf_map_addr() to move to next address in pool (like 172.16.0.2). while investigating issue I've also noticed an oddity for small random pools such as 192.168.1.32/28. One would expect the addresses for nat will be randomly picked from range .32 - .47 in this case. however the random selection yield significantly more (like 20%) addresses ending by .32 In order to fix it we make random pool to use arc4random_uniform(~mask + 1) instead of current arc4random(). feedback by claudio@ tested by hrvoje@

2022-08-02Correctly detect xmem operations faulting on missing pages on 88110.Miod Vallat
These must be handled as write faults rather than read faults, since xmem performs both a read and a write, and unlike on 88100, we don't have an easy bit to check. This solves libcrypto spinning on its locks on 88110.
2022-08-02Bring back the direct map optimization when PMAP_PREFER isn't defined.Martin Pieuchot
PMAP_PREFER is checked to prevent cache aliasing issues when the physical page is mapped at different virtual addresses. This speeds up file-based mmap faults. ok kettenis@

2022-07-31Replace selwakeup() with KNOTE() in audio(4)Visa Hankala
KNOTE() is safe to use at IPL_AUDIO. Remove the now-unnecessary deferring that uses soft interrupts. Remove selwakeup() calls from audio_detach() because klist_invalidate() wakes up any remaining kevent/poll/select waiters. OK mpi@
2022-07-30Now that we have proper .text and .data sections we need to move dt_blob toPatrick Wildt
.data. dt_blob is a basic device tree that is populated from ACPI tables when booting with ACPI instead of DT. Since we're modifying its content we need to put it somewhere writeable. Found and proposed by mlarkin@ ok kettenis@ mlarkin@
2022-07-30Kill virtual address randomization for the EFI runtime. It was a neat ideaMark Kettenis
but it appears to be too fragile and now that we are using a 48-bit VA space for the EFI runtime we no longer need to call SetVirtualAddressMap() to make address fit into our pmap. Unbreaks the x13s. ok mlarkin@, patrick@

2022-07-29Replace the swap extent(9) usage by a blist data structure.Sebastien Marie
It makes uvm_swap_free() faster: extents have a cost of O(n*n) which doesn't really scale with gigabytes of swap. Based on initial work from mpi@ The blist implementation comes from DragonFlyBSD. The diff adds also a ddb(4) 'show swap' command to show the blist and help debugging, and fix some off-by-one in size printed during hibernate. ok mpi@
2022-07-29Allocate if_index before queue initVisa Hankala
Allocate the index of a new network interface early so that the index is available when the interface's queues are set up. This avoids unintended concentration on net_tq(0). Replace the kernel lock with an rwlock to serialize index map updates. The kernel lock is not reliable here because the memory allocation can sleep. Also, correct the "too many interfaces" condition because the valid index range is from 1 to USHRT_MAX. OK bluhm@
2022-07-28In the kernel exist functions to print routes, but they were notAlexander Bluhm
accessible from ddb. Implement "show all routes" to print routing tables, and "show route 0xfffffd807e9b0000" for a single route entry. Note that the rtable id is not part of a route entry, so it makes no sense to print it there. OK deraadt@

the mutex for the fragment list. Move this code before the critical section. Use ISSET() to make clear which flags are checked. OK mvs@

2022-07-28Zap outdated nd6_free() comment about staticKlemens Nanni
Added in 2002 r1.48 "sync with latest KAME [...]" along the attribute, but nd6_free() became a global void function in 2017 r1.212. Afaik static kernel functions are avoided to aid ddb'ugging and I presume the "significant changes in the kernel" bits of the comment stem from something 20 years ago no longer holding true today. Afterall, this change has been safe for five years. OK claudio

ok hastings@
2022-07-27Postpone calling the EFI SetVirtualAddressMap() interface until efi(4)Mark Kettenis
attaches. This prevents us from having to map the various EFI memory regions early on. These early mappings use 1G blocks. On Apple M1 systems, these blocks may overlap memory that isn't accessable. The CPU may speculatively access this inaccessable memory which will result in SError exceptions. ok deraadt@

2022-07-27Fix reconstructed softraid bootlineKlemens Nanni
With softraid, OBP's boot-file variable aka. bootline may contain the sofraid volume name and kernel file name delimited by a double colon, e.g. "sr0", "sr0a", "sr0:", "sr0a:", "sr0:/bsd" or "sr0a:/bsd". ofwboot parses this string, may fill in optional partition number ("a") and/or optional kernel file name ("/bsd") and always prints the fully qualified string reconstructed from parts as "Booting <bootline>": {0} ok boot my-devalias sr0 [...] Boot device: /virtual-devices@100/channel-devices@200/disk@0 File and args: sr0 [...] Booting sr0:a/bsd [...] {0} ok boot my-devalias sr0a:/bsd [...] Boot device: /virtual-devices@100/channel-devices@200/disk@0 File and args: sr0a:/bsd [...] Booting sr0:a/bsd [...] Swap partition and delimiter to fix the reconstructed string, making it suitable for copy/paste: Booting sr0a:/bsd This has not been an issue since the reconstructed string is only printed and not (re)used anywhere.

2022-07-27retire Rise CPU identification codeDaniel Dickman
The Rise mp6 was an x86 compatible CPU that was available for about a year from 1998 to 1999. Only the Kirin core was ever available while the Lynx core did not make it to market. Shortly after this CPU was released, SiS acquired Rise's technology and integrated it into their SiS55x SoC which used a different vendor string. Given how uncommon Rise CPUs are and given that we don't do anything if we detect such a CPU, remove the small amount of code used to identify them. OpenBSD should continue to run on these CPUs, they just won't be recognized as Rise CPUs explicitly. It is suspected that in the current code, a Rise CPU would not show CX8 in the dmesg despite supporting the CMPXCHG8B instruction. The Rise datasheet says that this cpuid feature bit is set to 0 to "circumvent a reported bug in Windows NT". This is only a cosmetic issue though as our kernel does not use CMPXCHG8B and our toolchain assumes it exists (we default to -march=i586). An interesting writeup on this topic is available here: https://www.geoffchappell.com/studies/windows/km/cpu/cx8.htm ok mlarkin@, deraadt@, jsg@
