2009-06-18gcov: add gcov profiling infrastructurePeter Oberparleiter1-0/+11
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).

reports The page allocation failure messages include a line that looks like page allocation failure. order:1, mode:0x4020 The mode is easy to translate but irritating for the lazy and a bit error prone. This patch adds a very simple helper script gfp-translate for the mode: portion of the page allocation failure messages. An example usage looks like mel@machina:~/linux-2.6 $ scripts/gfp-translate 0x4020 Source: /home/mel/linux-2.6 Parsing: 0x4020 #define __GFP_HIGH (0x20) /* Should access emergency pools? */ #define __GFP_COMP (0x4000) /* Add compound page metadata */ The script is not a work of art but it has come in handy for me a few times so I thought I would share.

Many developers use "/debug/" or "/debugfs/" or "/sys/kernel/debug/" directory name to mount debugfs filesystem for ftrace according to ./Documentation/tracers/ftrace.txt file. 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.

2009-06-11asm-generic: add a generic unistd.hArnd Bergmann1-3/+89
A new architecture should only define a minimal set of system calls while still providing the full functionality. This version of unistd.h has gone through intensive review to make sure that by default it only enables syscalls that do not already have a more featureful replacement. It is modeled after the x86-64 version of unistd.h, which unifies the syscall number definition and the actual system call table in a single file, in order to keep them synchronized much more easily. This first version still keeps legacy system call definitions around, guarded by various #ifdefs, and with numbers larger than 1024. The idea behind this is to make it easier for new architectures to transition from a full list to the reduced set. In particular, the new microblaze architecture that should migrate to using the generic ABI headers can at least use an existing uClibc source tree without major rewrites during the conversion.

2009-06-09kbuild: fix headers_exports with boolean expressionRussell King1-11/+37
When we had code like this in a header unifdef failed to deduct that the expression was always false - and we had code exported that was not intended for userspace. #if defined(__KERNEL__) && !defined(__ASSEMBLY__) int a; #endif This commit implment support in unidef which allows it to work out if an #if expression always evaluates true or false for symbols which are being undefined/always defined. The patch is slightly more complicated than I'd hoped because unifdef needs to see lines fully evaluated - doing otherwise causes it to mark the line as "dirty" and copy it over no matter what.

2009-06-09scripts/headers_check.pl: correct RE in header CONFIG leak checkRobert P. J. Day1-1/+1
Correct the regular expression in scripts/headers_check.pl to include '_' as a valid character in the class; otherwise, the check will report a "leaked" symbol of CONFIG_A_B_C as merely CONFIG_A. This patch will make no difference whatsoever in the current kernel tree as the call to the perl routine that does that check is currently commented out: &check_include(); &check_asm_types(); &check_sizetypes(); &check_prototypes(); # Dropped for now. Too much noise &check_config(); However, I noticed that problem when I was building the yum downloadable kernel source rpm for fedora 11 (beta), which *does* run that check, and that's where the problem became obvious.

2009-06-09kconfig: do not hardcode "include/config/auto.conf" filenameMarkus Heidelberg3-11/+16
Regardless of KCONFIG_AUTOCONFIG, the filename written as a Make target into "include/config/auto.conf.cmd" was always the default one. Of course this doesn't make it work for the Kernel kbuild system, since there the filename is hardcoded at several places in the Makefiles.

2009-06-09kconfig: do not hardcode ".config" filenameMarkus Heidelberg2-5/+6
Rather than hardcoding ".config" use conf_get_configname(), which also respects the environment variable KCONFIG_CONFIG. This fixes "make silentoldconfig" when KCONFIG_CONFIG is used and also suggests the given filename for "Load" and "Save as" in qconf.
