2012-08-30On SPARC64 VI/VII CPUs, use the sleep instruction while spinning to force aMark Kettenis
thread switch in the hope the other thread can do some useful work.
2012-08-30Slightly tweak the way we set up the code patch sections such that we canMark Kettenis
use them to patch inline assembly in C code as well.
2012-08-30Remove a useless test for "elem_count < 0", which can never be trueMatthew Dempsky
because elem_count has an unsigned type (size_t). Noted by Brad/Clang; no binary change on amd64 using GCC either.
2012-08-30Kill NOPIE and NOPIE_FLAGS in sparc64/stand. Binaries are identical accordingPascal Stumpf
to deraadt@, ok kettenis@
2012-08-30Add the possibility to map DMA memory non-cached, based on the i386/amd64Martin Pieuchot
implementation. For the moment only the BUS_DMA_NOCACHE macro is required to build drm on macppc but it will be used soon. ok kettenis@
2012-08-30Use only one macro instead of two to turn debug printf on.Martin Pieuchot
ok kettenis@
2012-08-30Use an explicit suffix for the "fld" instruction to shut up clang. The correctMark Kettenis
instruction is fldl sinze we try to load a double-precision value. GCC actually gets it wrong and emits "flds" (which is harmless). Pointed out by Brad. ok guenther@

2012-08-30Sloppy state tracking renders ICMP direction check uselessMike Belopuhov
and harmful as we might see only half of the connection in the asymmetric setups but ignore the state match. The bug was reported and fix was verified by Insan Praja <insan () ims-solusi ! com>. Thanks! OK mcbride, henning

rest of the code expects. from brad
2012-08-29Kill all NOPIE and NOPIE_FLAGS in i386/stand, replacing them with -fno-piePascal Stumpf
and -nopie directly. Binaries from a PIE system are identical to those from a recent snapshot. ok deraadt@
2012-08-29The low-level guts to support MTP (Multi-Threaded Processing) on theMark Kettenis
Fujitsu SPARC64-VI and SPARC64-VII CPUs. Since the two threads on each core share the TLBs of the core we cannot enter different mappings for the same virtual address. Instead we use a scratch register to store the per-cpu pointer. This is very similar to what we do on sun4v. For now we still only attach the first thread of each SPARC64-VI/VII core since we currently don't handle the VMT (Vertical Multi-Threading) of the SPARC64-VI very well.
2012-08-29Make sure the interrupt stack for the boot processor is properly aligned toMark Kettenis
a 64K boundary. This means we don't have to worry about virtual cache aliasing anymore since SPARC V9 CPUs have at most a 16K aliasing.
2012-08-29Change "struct reg" to include a few more registers. We now use the sameMark Kettenis
layout as NetBSD.
2012-08-29Handle T_IPROT traps from userland by call vm_fault() instead of doing anMark Kettenis
unconditional SIGSEGV. Fixes random SIGSEGVs during single-stepping. ok miod@
2012-08-29Get rid of all NOPIE and NOPIE_FLAGS in amd64/stand and use -fno-pie and -nopiePascal Stumpf
directly instead. This will be the approach taken by every other arch too in the near future. It is easier than relying on bsd.own.mk to set these correctly. discussed with and ok deraadt@

2012-08-28Add -nopie to LINKFLAGS on ELF architectures. Note that this needs anPascal Stumpf

2012-08-28Do not add SLAAC or privacy addresses when a static address in the same prefixsperreault
already exists. 5.1 and older did the right thing. 5.2 did not (mea culpa). Now we're back to doing the right thing. spotted by naddy. ok stsp.

2012-08-28Add __guard_local as a hidden symbol to ld.so, kernel, and everyMatthew Dempsky
executable and DSO (via crtbegin.c/crtbeginS.c). Not used yet, but needed before GCC can start emitting -fstack-protector code that uses them instead of __guard.
2012-08-28Get rid of several ill-defined concepts and use more informationMike Belopuhov
provided by the IOC. Cleanup scatter-gather code and add more comments. Tested by a "make build" and bonnie++ torturing on a SAS2004 with an IR firmware.

2012-08-25Better detection of the st16650 v1 (with the broken fifo). Gets rid ofMark Kettenis
false positives like the DUART on the MPC8347 as found on socppc. ok deraadt@
2012-08-25Turns out the v445 isn't happy at all if we touch the registers that dealMark Kettenis
with sleep mode. So skip the wakeup code as well if we are a serial console. The port on the v445 almost certainly isn't a real st16650 and probably doesn't implement sleep mode (perhaps someone cut the soft core down a bit too much?). But it is indistinguishable from it, so we have to deal with it. ok deraadt@

2012-08-23the chain_offset in mfii requests are in 16 byte units, not 4 likeDavid Gwynne
mpii. this stops the chip from freaking out on me when doing chained sgls. found by alex wilson who wins prizes.
2012-08-23Fix a race in rt2661 Tx interrupt processing which can cause Tx processingStefan Sperling
to get stuck with OACTIVE set, requiring 'ifconfig ral0 down up' to unwedge. Make space in the Tx queue from the rt2661_tx_dma_intr() handler, rather than waiting until rt2661_tx_intr() is run. The latter function now collects AMRR statistics only. AMRR node allocation is now separated from ieee80211_node allocation to make this possible. This commit also brings back the separation of OACTIVE flags for management and data Tx queues which I reverted in the previous commit. Inspired by ral commits by sephe@dragonflybsd and patch submission to misc@ by Roland Dreier http://marc.info/?l=openbsd-misc&m=125895269930106&w=2 Tested by myself, edd, jsg, Tobias Ulmer, Pieter Verberne, Tim van der Molen.

2012-08-23stupid code bug.David Gwynne
instead of initting the ccbs sgl dma virtual address, i was assigning it to the sense memories dva. this means we wouldnt be getting sense data where we thought it was, and passing NULL (does NULL mean anything over a pci bus?) to the hardware when we have long sgl chains. hopefully this fixes the NMIs ive been getting.
