| * | | tracing: Fix recordmcount.pl to handle sections with only weak functionsSteven Rostedt2009-08-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Roland Dreier found that a section that contained only a weak function in one of the staging drivers and this caused recordmcount.pl to spit out a warning and fail. Although it is strange that a driver would have a weak function, and this function only be used in one place, it should not be something to make recordmcount.pl fail. This patch fixes the issue in a simple manner: if only weak functions exist in a section, then that section will not be recorded.

Well we tracked it down and it is powerpc64 specific. Seems that in drivers/hwmon/lm93.c there's a function called: LM93_IN_FROM_REG() But PPC64 has function descriptors and the real function names (the ones you see in objdump) start with a '.'. Thus this in objdump you have: Disassembly of section .text: 0000000000000000 <.LM93_IN_FROM_REG>: 0: 7c 08 02 a6 mflr r0 4: fb 81 ff e0 std r28,-32(r1) The function name used is .LM93_IN_FROM_REG. But gcc considers symbols that start with ".L" as a special symbol that is used inside the assembly stage. The nm passed into recordmcount uses the --synthetic option which shows the ".L" symbols (my runs outside of the build did not include the --synthetic option, so my older patch worked). We see the function as a local. Now to capture all the locations that use "mcount" we need to have a reference to link into the object file a list of mcount callers. We need a reference that will not disappear. We try to use a global function and if that does not work, we use a local function as a reference. But to relink the section back into the object, we need to make it global. In this case, we run objcopy using --globalize-symbol and --localize-symbol to convert the symbol into a global symbol, link the mcount list, then convert it back to a local symbol. This works great except for this case. .L* symbols can not be converted into a global symbol, and the mcount section referencing it will remain unresolved.

| * | ftrace: Only update $offset when we update $ref_funcMatt Fleming2009-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The value of $offset should be the offset of $ref_func from the beginning of the object file. Therefore, we should set both variables together. This fixes a bug I was hitting on sh where $offset (which is used to calcualte the addends for the __mcount_loc entries) was being set multiple times and didn't correspond to $ref_func's offset in the object file. The addends in __mcount_loc were calculated incorrectly, resulting in ftrace dynamically modifying addresses that weren't mcount call sites.

* | fbdev: work around old compiler bugStephen Rothwell2009-06-30
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building with a 4.1.x compiler on powerpc64 (at least) we get this error: drivers/video/logo/logo_linux_mono.c:81: error: logo_linux_mono causes a section type conflict This was introduced by commit ae52bb2384f721562f15f719de1acb8e934733cb ("fbdev: move logo externs to header file"). This is a partial revert of that commit sufficient to not hit the compiler bug. Also convert _clut arrays from __initconst to __initdata. Sam said: Al analysed this some time ago. When we say something is const then _sometimes_ gcc annotate the section as const(?) - sometimes not. So if we have two variables/functions annotated __*const and gcc decides to annotate the section const only in one case we get a section type conflict.

* gcov: add gcov profiling infrastructurePeter Oberparleiter2009-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable the use of GCC's coverage testing tool gcov [1] with the Linux kernel. gcov may be useful for: * debugging (has this code been reached at all?) * test improvement (how do I change my test to cover these lines?) * minimizing kernel configurations (do I need this option if the associated code is never run?) The profiling patch incorporates the following changes: * change kbuild to include profiling flags * provide functions needed by profiling code * present profiling data as files in debugfs Note that on some architectures, enabling gcc's profiling option "-fprofile-arcs" for the entire kernel may trigger compile/link/ run-time problems, some of which are caused by toolchain bugs and others which require adjustment of architecture code. For this reason profiling the entire kernel is initially restricted to those architectures for which it is known to work without changes. This restriction can be lifted once an architecture has been tested and found compatible with gcc's profiling. Profiling of single files or directories is still available on all platforms (see config help text).

And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is existed in kernel source like ftrace, DRM, Wireless, Documentation, Network[sky2]files to mount debugfs filesystem. debugfs means debug filesystem for debugging easy to use by greg kroah hartman. "/sys/kernel/debug/" name is suitable as directory name of debugfs filesystem. - debugfs related reference: http://lwn.net/Articles/334546/ Fix inconsistency of directory name to mount debugfs filesystem. * From Steven Rostedt - find_debugfs() and tracing_files() in this patch.

| | | | | | | | | | | | | | | | | | | | | | The Blackfin arch has a discontiguous .text layout due to having on-chip instruction memory and no virtual memory support. As such, we need to add explicit checks for these additional .text regions.
