2012-03-19Only change the default boot device to a bootable softraid volume, if weJoel Sing
are able to handle the given discipline. At this stage amd64 boot(8) is limited to RAID 1. This makes life easier for users who are booting from a softraid crypto volume, but are loading a kernel from hd0a:/bsd. Tested by jrick@devio.us - thanks!

2012-03-15Take cd9660 support off the "obviously a floppy" install media, to findTheo de Raadt
new space. The same cannot be done yet with some other architectures which share the RAMDISK kernel amongst media types too tightly. I am investigating the horrific src/distrib cleanups required to fix that.

renamed.
2012-01-11Pass the DUID of the boot disk via bootduid instead of rootduid, since itJoel Sing
is the DUID that we booted from, which is not always going to be the same as the DUID that we mount root on.
2012-01-11Teach OpenBSD/amd64 boot(8) how to access softraid(8) volumes. ThisJoel Sing
allows a kernel to be loaded from a softraid RAID 1 volume. Furthermore, if you boot from a disk that is a member of a bootable softraid volume then it will default to booting from the softraid volume (sr[0-9]a:/bsd). Discussed with deraadt@

2012-01-07Check that we have pstates in _PSS before calling the pstate status MSR.Jonathan Gray
While the docs say we should check a bit in cpuid this should work as well. Fixes problems related a fictitious AMD machine dreamed up by Linux KVM. Reported/tested by Walter Haidinger, diff from Bryan Steele.

2011-10-15"TLS-lite": add kernel support for a per-thread userspace pointer,Philip Guenthe
for pointing to the thread-control-block. Support for mapping this to the correct hardware register can be added as it's finished; start with support for amd64, sparc, and sparc64. Includes syscalls for getting and setting it (for a portable __errno implementation) as well as creating a new thread with an initial value for it. discussed with miod@, kettenis@, deraadt@; committing to get the syscalls in with the impending libc bump and do further refinements in tree
2011-10-13I'm sick and tired of people doing misalgned reads and writes to PCI configMark Kettenis
space and not noticing because they only test on amd64. So enforce alignment there as well, at least for a little while such that we find those bugs and force people to fix them.

they apply. ok oga@ deraadt@
2011-10-10Introduce pci_probe_device_hook(pci_chipset_tag_t, struct pci_attach_args *).Miod Vallat
This mandatory function will get invoked in pci_probe_device(), and allows a pci host driver to alter the pci_attach_args passed to a device when attaching. This function will also, if returning non-zero, cause the device to be skipped completely during all the phases of the PCI device discovery (i.e. ressource enumeration, ressource assignment, and actual attachment). This particular feature is experimental and might be reverted in the future (or the scope narrowed to device attachment only). A dummy #define pci_probe_device_hook() 0 is added to all platforms except sgi, where real functions (currently only returning 0) are added; real meat will be added shortly. Discussed at s2k11, no objection from the usual suspects.

Since the underlying types of the int_fast types are set by machine/_types.h, put internal macros in that same file and define the exposed INT_FAST*_{MIN,MAX} macros from those. ok millert@, kettenis@

2011-08-17Assembler implementation of the GCM mode using the Carry-lessMike Belopuhov
Multiplication (CLMUL) instruction found in the new Intel and future AMD CPUs. Done about a year ago and was rotting in my trees until Ryan prodded Theo to read the white paper and figure out the license issues. Apparently, there are none. All C code and SSE glue code was written by me, while the GF multiplication function is taken from the CLMUL white paper, specifically Figure 6: "Code Sample - Performing Ghash Using Algorithms 1 and 5".

2011-07-08When reading dos labels use DOS_LABELSECTOR and don't use LABELOFFSET. For ↵Kenneth R Westerback
all these arch's LABELSECTOR == DOS_LABELSECTOR == 1, and LABELOFFSET == 0. Thus, to quote bob, "This is a no-op". Makes the expression used when writing label the same as the one used in readdoslabel().

2011-07-07There is a bunch of places in the kernel entry points where we don'tArtur Grabowski
hold the kernel lock, but still need call one function that needs it. Instead of grabbing the lock all over the place, move the locks into the affected functions: trapsignal, scdebug*, ktrsyscall, ktrsysret, systrace_redirect and ADDUPROF. In the cases we already hold the biglock we'll just recurse. kettenis@, beck@ ok
