powerpc/ptrace: Enable support for Performance Monitor registers

2016-08-01T01:15:24Z

This patch enables support for Performance monitor registers related ELF core note NT_PPC_PMU based ptrace requests through PTRACE_GETREGSET, PTRACE_SETREGSET calls. This is achieved through adding one new register sets REGSET_PMU in powerpc corresponding to the ELF core note sections added in this regard. It also implements the get, set and active functions for this new register sets added. Signed-off-by: Anshuman Khandual Signed-off-by: Simon Guo Signed-off-by: Michael Ellerman

2016-08-01T01:15:23Z

This patch enables support for EBB state registers related ELF core note NT_PPC_EBB based ptrace requests through PTRACE_GETREGSET, PTRACE_SETREGSET calls. This is achieved through adding one new register sets REGSET_EBB in powerpc corresponding to the ELF core note sections added in this regard.

powerpc/ptrace: Enable support for TM SPR state

2016-08-01T01:15:21Z

This patch enables support for TM SPR state related ELF core note NT_PPC_TM_SPR based ptrace requests through PTRACE_GETREGSET, PTRACE_SETREGSET calls. This is achieved through adding a register set REGSET_TM_SPR in powerpc corresponding to the ELF core note section added.

powerpc/ptrace: Enable support for NT_PPC_CVSX

2016-08-01T01:15:20Z

This patch enables support for TM checkpointed VSX register set ELF core note NT_PPC_CVSX based ptrace requests through PTRACE_GETREGSET, PTRACE_SETREGSET calls.

powerpc/module: Handle R_PPC64_ENTRY relocations

2016-01-13T01:37:05Z

GCC 6 will include changes to generated code with -mcmodel=large, which is used to build kernel modules on powerpc64le. This was necessary because the large model is supposed to allow arbitrary sizes and locations of the code and data sections, but the ELFv2 global entry point prolog still made the unconditional assumption that the TOC associated with any particular function can be found within 2 GB of the function entry point: func: addis r2,r12,(.TOC.-func)@ha addi r2,r2,(.TOC.-func)@l .localentry func, .-func To remove this assumption, GCC will now generate instead this global entry point prolog sequence when using -mcmodel=large: .quad .TOC.-func func: .reloc ., R_PPC64_ENTRY ld r2, -8(r12) add r2, r2, r12 .localentry func, .-func The new .reloc triggers an optimization in the linker that will replace this new prolog with the original code (see above) if the linker determines that the distance between .TOC. and func is in range after all. Since this new relocation is now present in module object files, the kernel module loader is required to handle them too. This patch adds support for the new relocation and implements the same optimization done by the GNU linker. Cc: stable@vger.kernel.org Signed-off-by: Ulrich Weigand Signed-off-by: Michael Ellerman

powerpc: Handle new ELFv2 module relocations

2014-04-23T00:05:29Z

The new ELF ABI tends to use R_PPC64_REL16_LO and R_PPC64_REL16_HA relocations (PC-relative), so implement them. Signed-off-by: Rusty Russell
