2009-08-12Apple is hopelessly inconsistent with their firmware, so some machines haveMark Kettenis
an extra smu-i2c-control node where others don't. Handle the difference. Makes the PowerMac9,1 actually find some i2c devices.
2009-08-12Add support for the "Slots Power" sensor on the PowerMac9,1.Mark Kettenis
2009-08-11Do not bother initializing bufpages in the md code if the computation isMiod Vallat
exactly the same the mi could will use if bufinit() is invoked with bufpages == 0.
2009-08-11With the SysV memory allocation changes, allocsys() doesn't do anythingMiod Vallat
anymore. Get rid of it completely.
2009-08-11The PowerMac9,1 has 4 sensors on its smu(4), so increase the maximum number.Mark Kettenis
Also add a check for the maximum number of sensors like we already have for the number of fans such that we avoid mysterious hangs on machines with more than 4 sensors.
2009-08-11uvm_scheduler() sounds important, but ``while(1) tsleep()'' is kinda lameBret Lambert
inline the loop in the one place it exists, and remove it from uvm adjust a comment mentioning it accordingly originally inspired by a diff fixing a comment from oga@ ok art@ beck@ miod@ oga@
2009-08-11fix some stupidity in x86 bus_space_map.Owain Ainsworth
right now, we do a pmap_kenter_pa(), we then get the pte (behind pmap's back) and check for the cache inhibit bit (if needed). If it isn't what we want (this is the normal case) then we change it ourselves, and do a manual tlb shootdown (i386 was a bit more stupid about it than amd64, too). Instead, make it so that like on some other archs (sparc64 comes to mind) you can pass in flags in the low bits of the physical address, pmap then does everything correctly for you. Discovered this when I had some code doing a lot of bus_space_maps(), it was incredibly slow, and profilling was dominated by pmap_tlb_shootwait(); discussed with kettenis@, miod@, toby@ and art@. ok art@
2009-08-11Recent alignment fixes seem to make bwi(4) work at leastKenneth R Westerback
semi-reliably on my Thecus. Let others play too. 'no objections' miod@ 'sure' deraadt@
2009-08-10The shutdown hook is no longer required now that we shutdown all interfacesJoel Sing
when rebooting. ok deraadt@ jasper@
2009-08-10use splhigh instead of splclock to block in the i386_ipiTheo de Raadt
fixes stability problems on some machines; ie. crashes in in cpu_idle_cycle from netbsd, via dhill
2009-08-10right now, we only increment ci_idepth in struct cpuinfo whenOwain Ainsworth
MULTIPROCESSOR is defined. This makes splassert incorrect for IPL_NONE on such kernels. Make this more similar to amd64, and move the inc and dec of ci_idepth into the interrupt vectors, and only leave biglock in the locking functions. ok kettenis@
2009-08-10gpio for amd64.Jonathan Gray
ok deraadt@
2009-08-09Introduce option DDB_STRUCT. Kernels compiled with this option (except onMiod Vallat
a few arches where toolchain limitations apply) will embed some symbolic information about the various structs used within the kernel, and have new ddb commands allowing struct display and some useful information gathering. Kernel rodata increase varies accross platforms from ~150KB to ~300KB. This option is not enabled by default.
2009-08-09No need to clean genassym{.,o} during `make clean', genassym.sh does thisMiod Vallat
for us.
2009-08-09Another lost bit for SysV message queues.Bret Lambert
2009-08-09Add a dummy <machine/conf.h> so that MI code can rely upon its existence.Miod Vallat
2009-08-09Forgot to commit this bit for the SysV message queue cleanup.Bret Lambert

2009-08-09No options TIMEZONE and DST in GENERIC kernels.Miod Vallat
2009-08-09Unconditionally enable checks for writable non-uequivalent mappings. They'reMark Kettenis
evil so we should complain about them until we have a way to fix them.
2009-08-09Compile OpenBSD/sgi without -traditional-cpp. From jsg@.Joel Sing
2009-08-09Use the ANSI/ISO token paste operator. Requested by jsg@Joel Sing
ok miod@ jsg@
2009-08-09if extent_alloc() fails, we don't clear the iomap properly beforeOwain Ainsworth
returning an error. so next time we mess around, we may get annoying printfs. Fix this. ok kettenis@

2009-08-09MCLGETI() will now allocate a mbuf header if it is not provided, thusTheo de Raadt
reducing the amount of splnet/splx dancing required.. especially in the worst case (of m_cldrop) ok dlg kettenis damien
2009-08-09Rototill system V message queues.Bret Lambert
No longer allocate a static amount of memory for messages in MD boot path; message queues, message metadata, and message data now all use dynamic memory, which means that runtime sysctls should now be trivial to implement. Since I'm going to be around all week to fix any breakage, this should probably just go in now.
2009-08-09Clear the upper part of 64 bit memory BARs, for they show up as 0xffffffffMiod Vallat
otherwise. Found the hard way by jasper@, playing with a bge card.
2009-08-08add alc(4) to the i386 and amd64 RAMDISK_CD configsKevin Lo
2009-08-08alc(4) is a driver for the Atheros AR8131/AR8132 ethernet chip.Kevin Lo
this driver was written by Pyun YongHyeon from FreeBSD. "go ahead" deraadt@
2009-08-06Make sure <machine/cpu.h> includes <machine/intr.h> when included with _LOCOREMiod Vallat
defined; cp0access.S relies on this.
2009-08-06Work in progress support for Loongson2E/2F processors; need option CPU_LOONGSON2Miod Vallat
in the kernel to be brought in, due to invasive differences in tlb operation. Comes with a separate cache operations file due to the cache being R5k-style with R10k-style way number encoding.
2009-08-06R4k-style coprocessor 0 config register uses 3 bits wide fields to tellMiod Vallat
L1 caches sizes; fix the masking accordingly.
2009-08-06Remove _InvalidateICachePage cache op, it isn't used by anything.Miod Vallat
2009-08-06Only compile RM7000 performance counter support if defined(RM7K_PERFCNTR).Miod Vallat
This code needs to be cleaned up, and made more generic to work with other processors counters as well.
2009-08-06By popular demand and peer pressure, check-in work in progress work to supportMiod Vallat
the Yeelong Lemote mips-based netbook. Kernel bits only for now, needs polishing; most of this work done during h2k9 last month, although the porting effort started earlier this year.
2009-08-06reintroduce the uvm_tree commit.Owain Ainsworth
Now instead of the global object hashtable, we have a per object tree. Testing shows no performance difference and a slight code shrink. OTOH when locking is more fine grained this should be faster due to lock contention on uvm.hashlock. ok thib@, art@.

2009-08-02Dynamic buffer cache support - a re-commit of what was backed outBob Beck
after c2k9 allows buffer cache to be extended and grow/shrink dynamically tested by many, ok oga@, "why not just commit it" deraadt@
2009-08-02Never return nonzero in a device activate method invoked with DVACT_ACTIVATE,Miod Vallat
for this prevents it to be invoked with DVACT_DEACTIVATE later. This had been sweeped some time ago already, but bad constructs crept in again.
2009-07-31on error, just call unload() instead of doing all the actions that itOwain Ainsworth
would do manually. sparc64 does a similar thing already. ok kettenis@

or'ed together, even on platforms where bus_space_barrier() ignores the barrier argument yet.

2009-07-30Disable interrupts when we enter cpu_intr() and enable them again when leavingMark Kettenis
that function. It seems this function was intended to be called with interrupts disabled but that is not (no longer?) the case. As a result there were some races accessing the list of interrupt handlers and we would leave the function with interrupts disabled if there were any interrupts pending. This could make us end up in the idle loop with interrupts disabled, which would "hang" the machine. Found with help from deraadt@
