2013-05-30fix typos in some commentsMike Larkin
2013-05-30Switch to using unhyphenated VIA padlock mnemonics. VIA abandoned theMatthew Dempsky
hyphen in their official programming guide sometime between 2003 and 2005, and Clang's integrated assembler does not support hyphenated mnemonics. ok jsg, deraadt
2013-05-21de-static-ize prototypes as well, which makes these functions not-staticMark Kettenis
for real! Pointed out by Alexey E. Suslikov.
2013-05-21remove unused cpu_lock code (where it is truly unused). it is notTed Unangst
part of the future we have planned. middling ok from a few
2013-05-20de-static-ize, such that people don't get confused by aesni failures onMark Kettenis
AMD hardware the next time somebody tries to run on a broken KVM hypervisor.
2013-05-16Implement a mechanism to establish interrupt handlers that don't grab theMark Kettenis
kernel lock upon entry through a new IPL_MPSAFE flag/level.
2013-05-12Tell wsdisplay(4) to switch back to the console screen upon entering ddb(4).Mark Kettenis
This gives users a decent chance to see panic messages and interact with ddb(4) when they're running X on hardware for which we have a KMS driver. Currently that means inteldrm(4). ok jsg@, guenther@
2013-05-12Take the kernel lock and call the actual interrupt handler from aAlexandre Ratchov
single c function. This will hopefully make easier to stop taking the kernel lock when running "mp safe" interrupt handlers. help from ok kettenis

2013-05-06the use of modern intel performance counter msrs to measure the number ofDavid Gwynne
cycles per second isnt reliable, particularly inside "virtual" machines. cpuspeed can be calculated as 0, which causes a divide by zero later on which is bad. this goes to more effort to detect if the performance counters are in use by the hypervisor, or detecting if they gave us a cpuspeed of 0 so we can fall through to using rdtsc. ok jsg@
2013-04-24Use the manufacturer-supplied bios serial/uuid as a source ofBret Lambert
uniqueness to seed the random pool; although it's somewhat hit-or-miss, as serial numbers of 123456789 (I have the same combination on my luggage!) and lazy uuid instantiation mean it's not as unique as we would like. Still, on those boards where the manufacturer isn't a slacker, it's better than nothing... ok deraadt@
2013-04-23Include udivdi3/umoddi3 when compiling the amd64/i386 boot blocks - theyJoel Sing
are needed for the upcoming type changes. ok deraadt@

2013-04-04zap redundant assignmentsAlexander Hall
2013-04-01Do not expose the trap T_* values to userland, since they invade theTheo de Raadt
namespace a bit much. These are the names for the value encoded in core.c_ucode or siginfo.si_trapno, but userland never looks directly and only cares about the abstract signal code. ok guenther
2013-03-31try to avoid pulling in pte.h and other more crazy things. Checked againstTheo de Raadt
the things that libkvm needs.
2013-03-30reorder include search directories. cuts lookups by quite a bit.Ted Unangst

2013-03-29put urtwn in big ramdisks so I can use it for upgradesTed Unangst
2013-03-28Add STRONG_ALIAS macros to be used from assembly code in libc andMartynas Venckus
libm. While at it, remove now unused workarounds for lint. Agreed by kettenis@, guenther@, matthew@.
2013-03-28Add __strong_alias macros for all architectures to be able to aliasMartynas Venckus
another symbol without weak attribute. To be used in libc and libm soon. Agreed by kettenis@, guenther@, matthew@.

2013-03-23refactor sys/param.h and machine/param.h. A lot of #ifdef _KERNEL is addedTheo de Raadt
to keep definitions our of user space. The MD files now follow a consistant order -- all namespace intrusion is at the tail can be cleaned up independently. locore, bootblocks, and libkvm still see enough visibility to build. Checked on 90% of platforms...

2013-03-12Fix kernel profiling on MP systems by using per-CPU buffers and teachMartin Pieuchot
kgmon(8) to deal with them, this time without public header changes. Previously various CPUs were iterating over the same global buffer at the same time to modify it and never ended. This diff includes some ideas submited by Thor Simon to NetBSD via miod@. ok deraadt@, mikeb@, haesbaert@

2013-01-29the bus_space api implies that there's a bus endianness that it willDavid Gwynne
swap for you to the hosts endianness. sometimes you dont want this hand holding and just want raw access to the registers. bus_space does have stuff to do this already, but they deal with buffers which can be awkward if you just want to get or set a single register. this adds the following to i386 and amd64: bus_space_read_raw_2() bus_space_read_raw_4() bus_space_read_raw_8() bus_space_write_raw_2() bus_space_write_raw_4() bus_space_write_raw_8() sparc64 already implements this, even though it wasnt part of the official api. how handy. i'll do other archs as i can. kettenis@ and miod@ seem ok with this
