MIPS: Define RUNTIME_DISCARD_EXIT in LD script

2023-04-21T21:59:43Z

MIPS's exit sections are discarded at runtime as well. Fixes link error: `.exit.text' referenced in section `__jump_table' of fs/fuse/inode.o: defined in discarded section `.exit.text' of fs/fuse/inode.o Fixes: 99cb0d917ffa ("arch: fix broken BuildID for arm64 and riscv") Reported-by: "kernelci.org bot" Signed-off-by: Jiaxun Yang Signed-off-by: Thomas Bogendoerfer

MIPS: cevt-r4k: Offset the value used to clear compare interrupt

2023-02-27T22:45:17Z

In c0_compare_int_usable we clear compare interrupt by write value just read out from counter to compare register. However sometimes if those all instructions are graduated together then it's possible that at the time compare register is written, the counter haven't progressed, thus the interrupt is triggered again. It also applies to QEMU that instructions is executed significantly faster then counter. Offset the value used to clear interrupt by one to prevent that happen.

MIPS: smp-cps: Don't rely on CP0_CMGCRBASE

2023-02-27T22:44:57Z

CP0_CMGCRBASE is not always available on CPS enabled system such as early proAptiv. For early SMP bring up where we can't safely access memeory, we patch the entry of CPS NMI vector to inject CMGCR address directly into register during early core bringup. For VPE bringup as the core is already coherenct at that point we just read the variable to obtain the address. Signed-off-by: Jiaxun Yang Signed-off-by: Thomas Bogendoerfer

MIPS: vpe-mt: drop physical_memsize

2023-02-20T14:11:01Z

When neither LANTIQ nor MIPS_MALTA is set, 'physical_memsize' is not declared. This causes the build to fail with: mips-linux-ld: arch/mips/kernel/vpe-mt.o: in function `vpe_run': arch/mips/kernel/vpe-mt.c:(.text.vpe_run+0x280): undefined reference to `physical_memsize' LANTIQ is not using 'physical_memsize' and MIPS_MALTA's use of it is self-contained in mti-malta/malta-dtshim.c. Use of physical_memsize in vpe-mt.c appears to be unused, so eliminate this loader mode completely and require VPE programs to be compiled with DFLT_STACK_SIZE and DFLT_HEAP_SIZE defined.

MIPS: SMP-CPS: fix build error when HOTPLUG_CPU not set

2023-02-19T08:25:38Z

When MIPS_CPS=y, MIPS_CPS_PM is not set, HOTPLUG_CPU is not set, and KEXEC=y, cps_shutdown_this_cpu() attempts to call cps_pm_enter_state(), which is not built when MIPS_CPS_PM is not set. Conditionally execute the else branch based on CONFIG_HOTPLUG_CPU to remove the build error.

MIPS: Always use -Wa,-msoft-float and eliminate GAS_HAS_SET_HARDFLOAT

2023-01-26T03:41:16Z

-Wa,-msoft-float is tested with as-option, which will be a problem for clang with an upcoming change to move as-option to use KBUILD_AFLAGS instead of KBUILD_CFLAGS due to a lack of '-mno-abicalls' in KBUILD_AFLAGS at the point that this check occurs; $(cflags-y) is added to KBUILD_AFLAGS towards the end of this file. clang: error: ignoring '-fno-PIE' option as it cannot be used with implicit usage of -mabicalls and the N64 ABI [-Werror,-Woption-ignored] This could be resolved by switching to a cc-option check but '$(cflags-y)' would need to be added so that '-mno-abicalls' is present for the test. However, this check is no longer necessary, as -msoft-float is supported by all supported assembler versions (GNU as 2.25+ and LLVM 11+). Eliminate GAS_HAS_SET_HARDFLOAT and all of its uses, inlining SET_HARDFLOAT where necessary.
