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.

2009-08-09Unconditionally 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.

2009-08-09if 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.

2009-08-06Only 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@
2009-07-29Fix bogus comment; requested by deraadt@Mark Kettenis
2009-07-29Get rid of non-equivalent aliases of the pcb by moving the fpu state outMark Kettenis
of the pcb and using the p_addr member of 'struct proc' to calculate the address of the kernel stack when switching to virtual mode after taking a trap. Remove the now unecessary cache flushes; they're actually harmful since they create non-equivalent aliases. This seems to fix the memory corruption we have been observing from time to time. This diff does not rename fpu_curpcb, which is now somewhat incorrectly named. I hope to change things back again as soon as we are able to map the pcb 1:1.

2009-07-26Make sure all platforms understand the flags argument of bus_space_map() andMiod Vallat
bus_space_alloc() as a bitmask of flags, and not a boolean controlling cacheability; and make sure the three MI BUS_SPACE_MAP_xxx values documented in the manual page are defined on all platforms as well.
