2004-02-01Enable FXSR all the time, and cope with NPX/FXSR conversions; from netbsd.Theo de Raadt
Pass SSE/SSE2/XCRYPT flags out via syctl, and prepare for being able to do xcrypt-* in userland; ok naddy, tested a lot by pvalchev and jolan, also works on amd64 in 32bit mode
2003-12-31workaround: during npx exception testing, delay(1). For some reasonTheo de Raadt
amd64 (in 32 bit mode) and the new transmeta cpus want this, and lock up otherwise. very odd.
2003-12-24Sync ahc with NetBSD, which was in turn updated from FreeBSD by PascalKenneth R Westerback
Renauld of Network Storage Solutions, Inc. Many fixes, wider device support. In particular, the notorious 'Target 0' problem seems to be fixed. Does *not* include any updates to isa or eisa code beyond what was necessary to compile. Known issues: 1) Tagged Queuing is probably not optimal. 2) PPR negotiation may not be fully functional. 3) No support yet for freezing devices or channels. 4) The mechanism for preventing 'A' and 'B' channel confusion during probe can fail if scsibus > 254 found. 5) Requeuing I/O's not working. A workaround will be committed almost immediately. At the moment timeouts, SCSI message rejects, aborting SCB's and trying to freeze a device may cause incomplete i/o's to be reported as complete. 6) Verbosity and probe messages need work. 7) Last disk on bus seems to go through an extra re-negotiation. 8) >16 devices on an adapter will trigger the usual problems of total openings exceeding available SCB's under heavy load. Tested by deraadt@, beck@, miod@, naddy@, drahn@, marc@ amoung others. ok deraadt@.

2003-10-03Merge tty_attach() in ttymalloc() and tty_detach() in ttyfree(). The need forMiod Vallat
separate tty registering is gone now that sparc has switched to wscons, and this makes the code less error-prone. Also, remove tests for ttymalloc() failure, since it uses M_WAITOK. ok millert@ deraadt@, tested by various people as well besides me...
2003-08-15- remove ahc dependency, convert smc93cx6 into an attribute.Federico G. Schwindt
- support for 8 and 32 bit registers. from NetBSD. deraadt@ and krw@ testing and ok.
2003-08-15change arguments to suser. suser now takes the process, and a flagsTed Unangst
argument. old cred only calls user suser_ucred. this will allow future work to more flexibly implement the idea of a root process. looks like something i saw in freebsd, but a little different. use of suser_ucred vs suser in file system code should be looked at again, for the moment semantics remain unchanged. review and input from art@ testing and further review miod@

2001-11-18Revert niklas's broken ICU interrupt handling changes; deraadt@ okAaron Campbell
2001-11-12Redo the ICU interrupt handling system to better emulate an APIC system.Niklas Hallqvist
This is done by representing the current blockings of interrupts with a priority level instead of an interrupt mask. This makes it possible to share implementations for spl* functions/macros between both ICU and APIC (a must when going MP) systems. In this process, assign soft interrupts their own levels to match the way things will be on APIC systems where they actually will be real interrupts and not just bits in a pending mask as they are now. Heavily inspired by Bill Studenmunds SMP work in NetBSD

2001-11-05Switch everything to the new bus_dmamap_sync API.Artur Grabowski
Most work by Wilbern Cobb <vedge@csoft.org> with some fixes from me, mickey@ and drahn@.
2001-11-01Change d_mmap in struct cdevsw from:Artur Grabowski
int (*d_mmap) __P((dev_t, int, int)); to: paddr_t (*d_mmap) __P((dev_t, off_t, int)); This allows us to mmap devices past 4GB offsets.

2001-07-30Change:Artur Grabowski
int bus_dmamem_mmap(bus_dma_tag_t, bus_dma_segment_t, int, int, int, int); to: paddr_t bus_dmamem_mmap(bus_dma_tag_t, bus_dma_segment_t, int, int, off_t, int); To allow mmaping offsets larger than INT_MAX. And to simply make more sense.
