MIPS: Implement fueword and casueword* in assembly.

2018-03-12T22:10:06Z

Remove NO_FUEWORD so the 'e' variants are wrapped by the non-'e' variants. This is more correct and leaves sparc64 as the outlier. Reviewed by: jmallett, kib Obtained from: CheriBSD Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D14603

sys: further adoption of SPDX licensing ID tags.

2017-11-20T19:43:44Z

Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

Renumber copyright clause 4

2017-02-28T23:42:47Z

Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96

Subject: [PATCH] Pass MACHINE_ARCH on command line for MIPS kernels.

2016-11-18T16:23:31Z

While there, make param.h guess proper MACHINE_ARCH on hardfloat targets correctly as well, so tools like bmake can get their defaults right. This does not help the kernel case, since we compile them with forced -msoft-float and need to override an incorrect guess by param.h.

When attempting to satisfy mmap() requests for superpage alignment on

2016-04-30T19:29:03Z

64-bit MIPS, use superpage rather than physical-segment constants, or we may improperly fail to apply suitable alignment -- yet still allow mmap() to appear to succeed. Reviewed by: sson MFC after: 1 week Sponsored by: DARPA, AFRL

Add fueword(9) and casueword(9) functions. They are like fuword(9)

2014-10-28T15:22:13Z

and casuword(9), but do not mix value read and indication of fault. I know (or remember) enough assembly to handle x86 and powerpc. For arm, mips and sparc64, implement fueword() and casueword() as wrappers around fuword() and casuword(), which means that the functions cannot distinguish between -1 and fault. On architectures where fueword() and casueword() are native, implement fuword() and casuword() using fueword() and casuword(), to reduce assembly code duplication.

Rename VM_NDOMAIN into MAXMEMDOM and move it into machine/param.h in

Eliminate some definitions that haven't been used in a decade or more.

Assume a big-endian default on MIPS and drop the "eb" suffix from MACHINE_ARCH.

2012-03-29T02:54:35Z

This makes our naming scheme more closely match other systems and the expectations of much third-party software. MIPS builds which are little-endian should require and exhibit no changes. Big-endian TARGET_ARCHes must be changed: From: To: mipseb mips mipsn32eb mipsn32 mips64eb mips64 An entry has been added to UPDATING and some foot-shooting protection (complete with warnings which should become errors in the near future) to the top-level base system Makefile.

o) Add COMPAT_FREEBSD32 support for MIPS kernels using the n64 ABI with userlands

2012-03-03T08:19:18Z

using the o32 ABI. This mostly follows nwhitehorn's lead in implementing COMPAT_FREEBSD32 on powerpc64. o) Add a new type to the freebsd32 compat layer, time32_t, which is time_t in the 32-bit ABI being used. Since the MIPS port is relatively-new, even the 32-bit ABIs use a 64-bit time_t. o) Because time{spec,val}32 has the same size and layout as time{spec,val} on MIPS with 32-bit compatibility, then, disable some code which assumes otherwise wrongly when built for MIPS. A more general macro to check in this case would seem like a good idea eventually. If someone adds support for using n32 userland with n64 kernels on MIPS, then they will have to add a variety of flags related to each piece of the ABI that can vary. That's probably the right time to generalize further. o) Add MIPS to the list of architectures which use PAD64_REQUIRED in the freebsd32 compat code. Probably this should be generalized at some point. Reviewed by: gonzo
