2009-08-13Replace the error strings that were being passed around with much simplerTheo de Raadt
errnos. Note that the error strings are being ignored, since we long ago decided to not spam the console, and there is no other nice way to use the errors (without changing the ioctls to pass it back) The errno is now useful, since we can pass b_error from failing IO up, and the drive can decide how to use that ok miod

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.
2009-08-09Introduce 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.
2009-08-09MCLGETI() 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.
2009-08-02Dynamic 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@
2009-07-30Get rid of the obsolet BUS_BARRIER_xxx constants for bus_space_barrier(), onlyMiod Vallat
provide and use BUS_SPACE_BARRIER_xxx.
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.

2009-06-15Back out all the buffer cache changes I committed during c2k9. This reverts ↵Bob Beck
three commits: 1) The sysctl allowing bufcachepercent to be changed at boot time. 2) The change moving the buffer cache hash chains to a red-black tree 3) The dynamic buffer cache (Which depended on the earlier too). ok on the backout from marco and todd
2009-06-14Don't mess with the bounds in the lp if *partoffp is non-NULL, since thisTheo de Raadt
indicates that writedisklabel is trying to find the location for writing the label. If the lp is messed with, an invalid checksum is written. done with miod and kettenis, lots of moaning and gnashing of teeth, etc
2009-06-09backout interrupt diff until it the next round of fixesTheo de Raadt
2009-06-05Clamp the ending bound to the size of the disk. This makes disklabel -ATheo de Raadt
still do the right thing if the MBR has a lie in it
2009-06-04Recycle four ancient fields in the disklabel structure, replacing them withTheo de Raadt
bounds information, ie. the zone of the disk that OpenBSD can use. Have each pre-disklabel parser (MBR, DPME, or per-arch MD disklabel parsers) figure out this area and pass it up to userland. Then, delete all the same disk parsing code from disklabel(8) since the kernel passes it up. Lots and lots of - signs in the disklabel(8) code. Tested on as many platforms as possible, the fallout will be repaired as time goes on. To test, use disklabel -d <drive> and validate that the bounds do not overlap any boot blocks. This same information is used by disklabel -A... OK for the concept from krw, miod, and drahn

2009-06-02Somehow this change didn't get committed with the rest of the powepc interruptDale Rahn
fixes. Required to be changed at the same time.
2009-06-02Reintroduce the macppc interrupt subsystem rewrite. Several bugs haveDale Rahn

2009-04-20Add a BUS_DMA_ZERO flag for bus_dmamem_alloc() to return zeroed memory.Owain Ainsworth
Saves every damned driver calling bzero(), and continues the M_ZERO, PR_ZERO symmetry.
2009-04-14Convert the waitok field of uvm_pglistalloc to "flags", more will be added soon.Owain Ainsworth
For the possibility of sleeping, the first two flags are UVM_PLA_WAITOK and UVM_PLA_NOWAIT. It is an error not to show intention, so assert that one of the two is provided. Switch over every caller in the tree to using the appropriate flag. ok art@, ariane@

2009-01-11Fix a sed bug in the makefile's depend target.Paul Irofti
What happened was that the output of mkdep was fed to a sed expression that trimmed a bit more than required and also failed to work when attempting to do make depend with pcc. Example: genassym_c.o: /tmp/genassym.whatever ../../../../../sys/param.h \ was changed to: assym.h: \ but what was intended was: assym.h: ../../../../../sys/param.h \ For the pcc -M output things were a bit different and after the make depend the genassym entry would still remain and make would fail. This affected all platforms except amd64 and sgi. Okay miod@.
