We have HIGH_RES_TIMERS to support SCHED_HRTICK. But SCHED_HRTICK is in kernel/Kconfig.hz where HZ values unsuitable for MIPS are defined. So we simply add this config in arch/mips/Kconfig as opposed to including the whole kernel/Kconfig.hz.

MIPS R6 removed quite a few R2 instructions. However, there is plenty of <R6 userland code so we add an in-kernel emulator so we can still be able to execute all R2 userland out there. The emulator comes with a handy debugfs under /mips/ directory (r2-emul-stats) to provide some basic statistics of the instructions that are being emulated.

This patch bring this back along with the ability to determine the name of the object file where the EPC and RA registers point at.

Only allow 32-bit microMIPS builds, we're not ready yet for 64-bit microMIPS support. QEMU does have support for the 64-bit microMIPS ISA and with minor tweaks it is possible to have a 64-bit processor emulated there that runs microMIPS code, so despite the lack of actual 64-bit microMIPS hardware there is a way to run 64-bit microMIPS Linux, but it can all be considered early development and we are not there yet. Userland tools are lacking too, e.g. GCC produces bad code: {standard input}: Assembler messages: {standard input}:380: Warning: wrong size instruction in a 16-bit branch delay slot And our build fails early on, so disable the configuration, for the sake of automatic random config checkers if nothing else. Whoever needs to experiment with 64-bit microMIPS support can revert this change easily. Signed-off-by: NMaciej W.

Add missing microMIPS support to Malta. Currently the kernel only enables support for the instruction set for the SEAD-3 board despite the fact processor features have nothing to do with the board a processor is installed in. In this case there is no way to run microMIPS software in a fully supported way under Linux on QEMU. QEMU supports the emulation of a Malta board, but does not emulate SEAD-3. Linux supports running microMIPS code on a SEAD-3 board, but hardcodes such support to off on an emulated Malta board even if the processor selected has the microMIPS instruction set implemented. Adding support for the SEAD-3 to QEMU is a major project. Flipping a bit in the kernel that shouldn't have been cleared in the first place is a trivial effort. Thus the answer is plain...

Load purgatory code in RAM and relocate it based on the location. Relocation code has been inspired by module relocation code and purgatory relocation code in kexec-tools. Also compute the checksums of loaded kexec segments and store them in purgatory. Arch independent code provides this functionality so that arch dependent bootloaders can make use of it. Helper functions are provided to get/set symbol values in purgatory which are used by bootloaders later to set things like stack and entry point of second kernel etc. Signed-off-by: NVivek Goyal <vgoyal@redhat.com> Cc: Borislav Petkov <bp@suse.de> Cc: Michael Kerrisk <mtk.manpages@gmail.com> Cc: Yinghai Lu <yinghai@kernel.org> Cc: Eric Biederman <ebiederm@xmission.com> Cc: H.

In light of the commit 16f77de8 (Revert "MIPS: Save/restore MSA context around signals") the MSA support in the kernel is incomplete. Until the replacement for the former sigcontext changes is agreed upon and in tree, mark MSA experimental & disable it by default. MSA is only implemented by one CPU supported by the kernel, the P5600. The P5600 is a 32 bit core, and thus MSA can only be used when the experimental CONFIG_MIPS_O32_FP64_SUPPORT option is enabled. Therefore MSA is only being used in experimental settings anyway and this change doesn't actually make any difference beyond clarifying the state of MSA support.
