2015-05-10VM_MAX_KERNEL_ADDRESS is the end of the kva range not the end ofJonathan Gray
addressable virtual memory space but arm ports were using a value of 0xffffffff for this. Instead of using a shared VM_MAX_KERNEL_ADDRESS define add md VM_KERNEL_SPACE_SIZE defines based on the KERNEL_VM_SIZE values from the respective machdep.c files. djm's novena was hitting "panic: bufinit: can't reserve VM for buffers" without a similiar change. ok miod@

2015-05-05emul_native is only used for kernel threads which can't dump core, soPhilip Guenther
delete coredump_trad(), uvm_coredump(), cpu_coredump(), struct md_coredump, and various #includes that are superfluous. This leaves compat_linux processes without a coredump callback. If that ability is desired, someone should update it to use coredump_elf32() and verify the results... ok kettenis@
2015-04-30Remove SIZE_MAX from limits.h. It was added years ago before weTodd C. Miller
had a proper stdint.h. No ports fallout. OK guenther@ miod@
2015-02-15Change pmap_remove_holes() to take a vmspace instead of a map as its argument.Miod Vallat
Use this on vax to correctly pick the end of the stack area now that the stackgap adjustment code will no longer guarantee it is a fixed location.
2015-02-10Convert to uiomove().Miod Vallat
ok guenther@
2015-02-10First step towards making uiomove() take a size_t size argument:Miod Vallat
- rename uiomove() to uiomovei() and update all its users. - introduce uiomove(), which is similar to uiomovei() but with a size_t. - rewrite uiomovei() as an uiomove() wrapper. ok kettenis@

2015-01-18When restoring spsr values when handling traps use spsr_fsxc insteadJonathan Gray
of spsr_all so all the bits are restored. Using the msr instruction with spsr_all is treated the same as spsr_fc and does not include the status and extension fields (bits 23:8). This fixes the problem of some i.MX6 machines powering up with the big endian bit set in the extension field causing them to crash on returning from the first interrupt. From NetBSD.
2015-01-18Switch some uses of msr that only deal with interrupts/mode to useJonathan Gray
just the control field ('c' bits 7:0) instead of 'all' which includes the flags field ('f' bits 31:24) which isn't modified.
2015-01-18The 'mrs' instruction only deals with the whole register withoutJonathan Gray
masking. Remove the use of cpsr_all/spsr_all with 'mrs' and just use the register names. This matches the arm docs and avoids confusion as cpsr_all/spsr_all don't include bits 23->8 when used with the 'msr' instruction but do with 'mrs'.

existing one for earlier arm revisions.
2015-01-12Enable lid suspends by default in the kernel, and remove the question fromTheo de Raadt
the installer. We used a full release cycle to learn that suspend/resume is reliable enough for this default. Personal policy can disable this using machdep.lidsuspend=0 in /etc/sysctl.conf ok more people begging, and less people whining
2015-01-11armv6 introduced opcodes for reversing words in registers. we canDavid Gwynne
use these on armv7 as a backend for byteswapping things that endian.h provide. i dunno if its faster, but it makes smaller code. saves 30k on GENERIC-OMAP. ok jsing@ bmercer@ jsg@

2014-07-12Tackle the endian.h mess. Make it so that:Philip Guenther
* you can #include <sys/endian.h> instead of <machine/endian.h>, and ditto <endian.h> (fixes code that pulls in <sys/endian.h> first) * those will always export the symbols that POSIX specified for <endian.h>, including the new {be,le}{16,32,64}toh() set. c.f. http://austingroupbugs.net/view.php?id=162 if __BSD_VISIBLE then you also get the symbols that our <machine/endian.h> currently exports (ntohs, NTOHS, dlg's bemtoh*, etc) * when doing POSIX compiles (not __BSD_VISIBLE), then <netinet/in.h> and <arpa/inet.h> will *stop* exporting the extra symbols like BYTE_ORDER and betoh* ok deraadt@
2014-07-11CPU_BUSY_CYCLE(): A new MI statement for busy loop power reductionMasao Uebayashi
The new CPU_BUSY_CYCLE() may be put in a busy loop body so that CPU can reduce power consumption, as Linux's cpu_relax() and FreeBSD's cpu_spinwait(). To start minimally, use PAUSE on i386/amd64 and empty on others. The name is chosen following the existing cpu_idle_*() functions. Naming and API may be polished later. OK kettenis@
