Drop function argument access syntax, because the function arguments depend on not only architecture but also compile-options and function API. And now, we have perf-probe for finding register/memory assigned to each argument. Signed-off-by:

DSOs don't have this problem because the kernel emits a PERF_MMAP for each new executable mapping it performs on monitored threads. To fix the kernel case we simulate the same behaviour, by having 'perf record' to synthesize a PERF_MMAP for the kernel, encoded like this: [root@doppio ~]# perf record -a -f sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.344 MB perf.data (~15038 samples) ] [root@doppio ~]# perf report -D | head -10 0xd0 [0x40]: event: 1 . . ... raw event: size 64 bytes . 0000: 01 00 00 00 00 00 40 00 00 00 00 00 00 00 00 00 ......@........ . 0010: 00 00 00 81 ff ff ff ff 00 00 00 00 00 00 00 00 ............... . 0020: 00 00 00 00 00 00 00 00 5b 6b 65 72 6e 65 6c 2e ........ [kernel . 0030: 6b 61 6c 6c 73 79 6d 73 2e 5f 74 65 78 74 5d 00 kallsyms._text] . 0xd0 [0x40]: PERF_RECORD_MMAP 0/0: [0xffffffff81000000((nil)) @ (nil)]: [kernel.kallsyms._text] I.e. we identify such event as having: .pid = 0 .filename = [kernel.kallsyms.REFNAME] .start = REFNAME addr in /proc/kallsyms at 'perf record' time and use now a hardcoded value of '.text' for REFNAME. Then, later, in 'perf report', if there are any kernel hits and thus we need to resolve kernel symbols, we search for REFNAME and if its address changed, relocation happened and we thus must change the kernel mapping routines to one that uses .pgoff as the relocation to apply. This way we use the same mechanism used for the other DSOs and don't have to do a two pass in all the kernel symbols. Reported-by:

To avoid the funny: [root@doppio ~]# perf record -a -f sleep 2s [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.334 MB perf.data (~14572 samples) ] [root@doppio ~]# perf report --no-call-graph selected -g but no callchain data. Did you call perf record without -g?

While processing kernel perf callchains, an bad entry can be considered as a valid stack pointer but not as a kernel address. In this case, we hang in an endless loop. This can happen in an x86-32 kernel after processing the last entry in a kernel stacktrace. Just stop the stack frame walking after we encounter an invalid kernel address. This fixes a hard lockup in x86-32. Signed-off-by:

Mikael Pettersson authored
When sata_promise encounters an overrun or underrun error it translates that to a libata AC_ERR_HSM, causing a hard reset. Since over/under-runs were thought to be rare and transient, this action seemed reasonable. Unfortunately it turns out that the controller throws overrun errors when e.g. hal polls a CD or DVD writer containing blank media, causing long sequences of hard resets and retries before EH finally gives up. This patch updates sata_promise to classify over/under-runs as AC_ERR_OTHER instead. This allows libata EH and upper layers to retry or fail the operation as they see fit without the disruption caused by repeated hard resets. This fixes a problem using a DVD-RAM drive with sata_promise, reported by Thomas Schorpp. I also tested it on a DVD-RW drive. Signed-off-by:
