2016-09-03Increase the number of mbufs on most architectures. This is basedAlexander Bluhm
on a guess how much memory a typical machine has. If the value is too high, users may run out of kernel memory. Then we will have to adjust this again. OK claudio@ deraadt@

2016-08-17use a register variable to get at the curcpu pointer in %g7David Gwynne
this lets us define curcpu(), cpu_number(), etc as derefs of this variable rather than having to write asm to copy it into another register for the same derefs. this provides shorter inlined code that wastes less registers. ok kettenis@ who notes we use this these on other archs already

2016-06-13rework sparc64 splfoo functions to be more consistent with other archsDavid Gwynne
this also moves us toward having an MI splraise(). sparc64 (and sparc) are different to the other archs because they have macros that build templates. each spl uses that macro to create an instance of an inline function specific to that spl call. this moves it to having a single splraise inline that the spl api is defined with. eg, #define splfoo() _splraise(IPL_FOO). ok kettenis@

2016-05-23Place a cpu-dependent trap/illegal instruction over the remainder of theTheo de Raadt
sigtramp page, so that it will generate a nice kernel fault if touched. While here, move most of the sigtramps to the .rodata segment, because they are not executed in the kernel. Also some preparation for sliding the actual sigtramp forward (will need some gdb changes) ok mlarkin kettenis
2016-05-21hand-massage sendsig() and sys_sigreturn() to be much more similarTheo de Raadt

2016-05-19Implement OF_is_compatible(9).Mark Kettenis
2016-05-10SROP mitigation. sendsig() stores a (per-process ^ &sigcontext) cookieTheo de Raadt
inside the sigcontext. sigreturn(2) checks syscall entry was from the exact PC addr in the (per-process ASLR) sigtramp, verifies the cookie, and clears it to prevent sigcontext reuse. not yet tested on landisk, sparc, *88k, socppc. ok kettenis
2016-05-04Some hardware (such as the onboard dc(4) of the Netra X1) has a broken DMAMark Kettenis
engine that might attempt to read beyond the end of the buffer that was programmed. The IOMMU catches this "DMA overrun" and throws an unrecoverable error at us, at which point we have no choice but to panic. To avoid this implement a BUS_DMA_OVERRUN flag that maps an additional scratch page at the end of the vdma address range. DMA requests will spill over into this page, which just returns zeroes. Thanks to matthieu@ for giving me access to a machine with the problem. ok deraadt@, beck@
2016-05-04Initial support for MSI-X. Only supported on amd64 for now. I have diffs toMark Kettenis
actually use this in em(4) and xhci(4), but I'm not committing those yet because we almost certainly need to save and restore the MSI-X registers during suspend/resume. However, this allows mpi@ to play with multiple-vector support in networking hardware. Requested by mpi@ ok mlarkin@, mikeb@
2016-05-03Revert previous commit. Calling sched_init_cpu() fromMark Kettenis
cpu_boot_secondary_processors() break suspend/resume.
2016-04-29Call sched_init_cpu() just before booting secondary CPUs.Martin Pieuchot
This prevent the scheduler from scheduling tasks to CPUs not beeing able to execute them during the boot process. ok visa@, kettenis@
2016-04-29Do not remove local symbols from the table.Martin Pieuchot
ddb(4) can now see static functions. That doesn't mean we should start declaring functions as ``static'', however it helps for the few existing exceptions. ok deraadt@, kettenis@

The goal is to include it in the list of functions that must not be instrumented. All ddb(8) functions should be in this list and have their names start with 'db_'. ok visa@, deraadt@

2016-02-26Remove stale RAIDframe entries from chrtoblktbl.natano
