s390: convert ".insn" encoding to instruction names

2022-03-10T14:58:17Z

With z10 as minimum supported machine generation many ".insn" encodings could be now converted to instruction names. There are couple of exceptions - stfle is used from the als code built for z900 and cannot be converted - few ".insn" directives encode unsupported instruction formats The generated code is identical before/after this change.

s390/extable: move EX_TABLE define to asm-extable.h

2022-03-07T23:33:00Z

Follow arm64 and riscv and move the EX_TABLE define to asm-extable.h which is a lot less generic than the current linkage.h. Also make sure that all files which contain EX_TABLE usages actually include the new header file. This should make sure that the files always compile and there won't be any random compile breakage due to other header file dependencies.

s390/cpum_sf: Replace function name in debug statements

2019-11-30T09:52:46Z

Replace hard coded function names in debug statements by the "%s ...", __func__ construct suggested by checkpatch.pl script. Use consistent debug print format of the form variable blank value. Also add leading 0x for all hex values. Print allocated page addresses consistantly as hex numbers with leading 0x. Signed-off-by: Thomas Richter Signed-off-by: Vasily Gorbik

s390/cpu_mf: mark function(s) __always_inline

2019-10-04T14:37:33Z

Always inline asm inlines with variable operands for "i" constraints, since they won't compile if the compiler would decide to not inline them. Reported-by: Michal Kubecek Signed-off-by: Heiko Carstens Signed-off-by: Vasily Gorbik

s390/cpu_mf: replace stcctm5() with the stcctm() function

2019-02-22T08:19:53Z

Remove the stcctm5() function to extract counters from the MT-diagnostic counter set with the stcctm() function. For readability, introduce an enum to map the counter sets names to respective numbers for the stcctm instruction. Signed-off-by: Hendrik Brueckner Signed-off-by: Martin Schwidefsky

s390/cpu_mf: add store cpu counter multiple instruction support

2019-02-22T08:19:52Z

Add support for the STORE CPU COUNTER MULTIPLE instruction to extract a range of counters from a counter set. An assembler macro is used to create the instruction opcode because the counter set identifier is part of the instruction and, thus, cannot be easily specified as parameter.

s390/cpum_sf: save TOD clock base in SDBs for time conversion

2018-07-31T09:02:27Z

Processing the samples in the AUX-area by perf requires the computation of respective time stamps. The time stamps used by perf are based on the monotonic clock. To convert the TOD clock value contained in an SDB to a monotonic clock value, the TOD clock base is required. Hence, also save the TOD clock base in the SDB.
