2014-04-23powerpc: modules: implement stubs for ELFv2 ABI.Rusty Russell
ELFv2 doesn't use function descriptors, because it doesn't need to load a new r2 when calling into a function. On the other hand, you're supposed to use a local entry point for R_PPC_REL24 branches. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2014-04-23powerpc: modules: skip r2 setup for ELFv2Rusty Russell
ELFv2 doesn't need to set up r2 when calling a function. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2014-04-23powerpc: modules: use r12 for stub jump address.Rusty Russell
In ELFv2, r12 is supposed to equal to PC on entry to a function. Our stubs use r11, so change swap that with r12. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2014-04-23powerpc: modules: change r2 save/restore offset for ELFv2 ABI.Rusty Russell
ELFv2 uses a different stack offset (24 vs 40) to save r2. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2014-04-23powerpc: modules: comment about de-dotifying symbols when using the ELFv2 ABI.Rusty Russell
ELFv2 doesn't use function descriptors, so we don't expect symbols to start with ".". But because depmod and modpost strip ".", and we have the special symbol ".TOC.", we still need to do it. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2014-04-23powerpc: Handle new ELFv2 module relocationsRusty Russell
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 <rusty@rustcorp.com.au>
2014-04-23powerpc: Fix up TOC. for modules.Rusty Russell
The kernel resolved the '.TOC.' to a fake symbol, so we need to fix it up to point to our .toc section plus 0x8000. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2014-04-23powerpc: module: handle MODVERSION for .TOC.Rusty Russell
For the ELFv2 ABI, powerpc introduces a magic symbol ".TOC.". If we don't create a CRC for it (minus the leading ".", since we strip that) we get a modpost warning about missing CRC and the CRC array seems to be displaced by 1 so other CRCs mismatch too. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2014-04-23powerpc: EXPORT_SYMBOL(.TOC.)Rusty Russell
For the ELFv2 ABI, powerpc introduces a magic symbol ".TOC.". depmod then complains that this doesn't resolve (so does modpost, but we could easily fix that). To export this, we need to use asm. modpost and depmod both strip "." from symbols for the old PPC64 ELFv1 ABI, so we actually export a "TOC.". Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2014-04-23powerpc: modules implement R_PPC64_TOCSAVE relocation.Rusty Russell
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2014-04-23powerpc: make module stub code endian independentRusty Russell
By representing them as words, rather than chars, we can avoid endian ifdefs. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2014-04-23powerpc: Fix ABIv2 issue with dereference_function_descriptorAnton Blanchard
Don't try and dereference a function descriptor on ABIv2. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Fix SMP issues with ppc64le ABIv2Anton Blanchard
There is no need to put a function descriptor in __secondary_hold_spinloop. Use ppc_function_entry to get the instruction address and put it in __secondary_hold_spinloop instead. Also fix an issue where we assumed cur_cpu_spec held a function descriptor. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc/tracing: TRACE_WITH_FRAME_BUFFER creates invalid stack framesAnton Blanchard
TRACE_WITH_FRAME_BUFFER creates 32 byte stack frames. On ppc64 ABIv1 this is too small and a callee could corrupt the stack by writing to the parameter save area (starting at offset 48). Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc/tm: Fix GOT save offset for ABIv2Anton Blanchard
The r2 TOC/GOT save offset is 40 on ABIv1 and 24 on ABIv2. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc/tm: Use STK_PARAMAnton Blanchard
Get rid of the tm specific STACK_PARAM and use STK_PARAM Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Fix unsafe accesses to parameter area in ELFv2Ulrich Weigand
Some of the assembler files in lib/ make use of the fact that in the ELFv1 ABI, the caller guarantees to provide stack space to save the parameter registers r3 ... r10. This guarantee is no longer present in ELFv2 for functions that have no variable argument list and no more than 8 arguments. Change the affected routines to temporarily store registers in the red zone and/or the top of their own stack frame (in the space provided to save r31 .. r29, which is actually not used in these routines). In opal_query_takeover, simply always allocate a stack frame; the routine is not performance critical. Signed-off-by: Ulrich Weigand <ulrich.weigand@de.ibm.com> Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Fix ABIv2 issues with stack offsets in assembly codeAnton Blanchard
Fix STK_PARAM and use it instead of hardcoding ABIv1 offsets. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Fix kernel thread creation on ABIv2Anton Blanchard
Change how we setup registers for ret_from_kernel_thread. In ABIv1, instead of passing a function descriptor in, dereference it and pass the target in directly. Use ppc_global_function_entry to get it right on both ABIv1 and ABIv2. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Fix branch patching code for ABIv2Anton Blanchard
The MMU hashtable and SLB branch patching code uses function pointers for the update sites. This creates a difference between ABIv1 and ABIv2 because we don't have function descriptors on ABIv2. Get rid of the function pointer and just point at the update sites directly. This works on both ABIs. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Use ppc_function_entry instead of open coding itAnton Blanchard
Replace FUNCTION_TEXT with ppc_function_entry which can handle both ABIv1 and ABIv2. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Add ABIv2 support to ppc_function_entryAnton Blanchard
Skip over the well known global entry point code for ABIv2. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Ignore .TOC. relocationsAnton Blanchard
The linker fixes up .TOC. relocations, so prom_init_check.sh should ignore them. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: ABIv2 function calls must place target address in r12Anton Blanchard
To establish addressability quickly, ABIv2 requires the target address of the function being called to be in r12. Fix a number of places in assembly code that we do indirect function calls. We need to avoid function descriptors on ABIv2 too. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Remove function descriptors and dot symbols on new ABIAnton Blanchard
ABIv2 doesn't have function descriptors or dot symbols. One new thing it does add is a function global and a local entry point, so add that to our _GLOBAL macro. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Create DOTSYM to wrap dot symbol usageAnton Blanchard
There are a few places we have to use dot symbols with the current ABI - the syscall table and the kvm hcall table. Wrap both of these with a new macro called DOTSYM so it will be easy to transition away from dot symbols in a future ABI. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Remove dot symbol usage in exception macrosAnton Blanchard
STD_EXCEPTION_COMMON, STD_EXCEPTION_COMMON_ASYNC and MASKABLE_EXCEPTION branch to the handler, so we can remove the explicit dot symbol and binutils will do the right thing. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Remove _INIT_GLOBAL(), _STATIC() and _INIT_STATIC()Anton Blanchard
Now there are no users of _INIT_GLOBAL(), _STATIC() and _INIT_STATIC() we can remove them. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Remove some unnecessary uses of _GLOBAL() and _STATIC()Anton Blanchard
There is no need to create a function descriptor for functions called locally out of assembly. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Don't use a function descriptor for system call tableAnton Blanchard
There is no need to create a function descriptor for the system call table. By using one we force the system call table into the text section and it really belongs in the rodata section. This also removes another use of dot symbols. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Remove superflous function descriptors in assembly only codeAnton Blanchard
We have a number of places where we load the text address of a local function and indirectly branch to it in assembly. Since it is an indirect branch binutils will not know to use the function text address, so that trick wont work. There is no need for these functions to have a function descriptor so we can replace it with a label and remove the dot symbol. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: No need to use dot symbols when branching to a functionAnton Blanchard
binutils is smart enough to know that a branch to a function descriptor is actually a branch to the functions text address. Alan tells me that binutils has been doing this for 9 years. Signed-off-by: Anton Blanchard <anton@samba.org>
2014-04-23powerpc: Don't build assembly files with ABIv2Anton Blanchard
We avoid ABIv2 when building c files since commit b2ca8c89 (powerpc: Don't use ELFv2 ABI to build the kernel). Do the same for assembly files. Signed-off-by: Anton Blanchard <anton@samba.org>

2014-04-20perf tools: Improve error reportingAdrien BAK
In the current version, when using perf record, if something goes wrong in tools/perf/builtin-record.c:375 session = perf_session__new(file, false, NULL); The error message: "Not enough memory for reading per file header" is issued. This error message seems to be outdated and is not very helpful. This patch proposes to replace this error message by "Perf session creation failed" I believe this issue has been brought to lkml: https://lkml.org/lkml/2014/2/24/458 although this patch only tackles a (small) part of the issue. Additionnaly, this patch improves error reporting in tools/perf/util/data.c open_file_write. Currently, if the call to open fails, the user is unaware of it. This patch logs the error, before returning the error code to the caller.

2014-04-20perf kvm: Fix 'Min time' counting in report commandAlexander Yarygin
Every event in the perf-kvm has a 'stats' structure, which contains max/min/average/etc times of handling this event. The problem is that the 'perf-kvm stat report' command always shows that 'min time' is 0us for every event. Example: # perf kvm stat report Analyze events for all VCPUs: VM-EXIT Samples Samples% Time% Min Time Max Time Avg time [..] 0xB2 MSCH 12 0.07% 0.00% 0us 8us 7.31us ( +- 2.11% ) 0xB2 CHSC 12 0.07% 0.00% 0us 18us 9.39us ( +- 9.49% ) 0xB2 STPX 8 0.05% 0.00% 0us 2us 1.88us ( +- 7.18% ) 0xB2 STSI 7 0.04% 0.00% 0us 44us 16.49us ( +- 38.20% ) [..] This happens because the 'stats' structure is not initialized and stats->min equals to 0. Lets initialize the structure for every event after its allocation using init_stats() function. This initializes stats->min to -1 and makes 'Min time' statistics counting work: # perf kvm stat report Analyze events for all VCPUs: VM-EXIT Samples Samples% Time% Min Time Max Time Avg time [..] 0xB2 MSCH 12 0.07% 0.00% 6us 8us 7.31us ( +- 2.11% ) 0xB2 CHSC 12 0.07% 0.00% 7us 18us 9.39us ( +- 9.49% ) 0xB2 STPX 8 0.05% 0.00% 1us 2us 1.88us ( +- 7.18% ) 0xB2 STSI 7 0.04% 0.00% 1us 44us 16.49us ( +- 38.20% ) [..] Signed-off-by: Alexander Yarygin <yarygin@linux.vnet.ibm.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Reviewed-by: David Ahern <dsahern@gmail.com> Link: http://lkml.kernel.org/r/1397053319-2130-3-git-send-email-borntraeger@de.ibm.com [ Fixing the perf examples changelog output ] Signed-off-by: Jiri Olsa <jolsa@redhat.com>
