2009-03-24dynamic debug: combine dprintk and dynamic printkJason Baron
This patch combines Greg Bank's dprintk() work with the existing dynamic printk patchset, we are now calling it 'dynamic debug'. The new feature of this patchset is a richer /debugfs control file interface, (an example output from my system is at the bottom), which allows fined grained control over the the debug output. The output can be controlled by function, file, module, format string, and line number. for example, enabled all debug messages in module 'nf_conntrack': echo -n 'module nf_conntrack +p' > /mnt/debugfs/dynamic_debug/control to disable them: echo -n 'module nf_conntrack -p' > /mnt/debugfs/dynamic_debug/control A further explanation can be found in the documentation patch.

2009-03-24platform: introduce module id table for platform devicesEric Miao
Now platform_device is being widely used on SoC processors where the peripherals are attached to the system bus, which is simple enough. However, silicon IPs for these SoCs are usually shared heavily across a family of processors, even products from different companies. This makes the original simple driver name based matching insufficient, or simply not straight-forward. Introduce a module id table for platform devices, and makes it clear that a platform driver is able to support some shared IP and handle slight differences across different platforms (by 'driver_data'). Module alias is handled automatically when a MODULE_DEVICE_TABLE() is defined. To not disturb the current platform drivers too much, the matched id entry is recorded and can be retrieved by platform_get_device_id().

2009-03-15kconfig: improve seed in randconfigIngo Molnar
'make randconfig' uses glibc's rand function, and the seed of that PRNG is set via: srand(time(NULL)); But 'time()' only increases once every second - freezing the randconfig result within a single second. My Nehalem testbox does randconfig much faster than 1 second and i have a few scripts that do 'randconfig until condition X' loops. Those scripts currently waste a lot of CPU time due to randconfig changing its seed only once per second currently. Change the seed to be micrseconds based. (I checked the statistical spread of the seed - the now.tv_sec*now.tv_usec multiplication there further improves it.)

2009-03-15kconfig: fix randconfig for choice blocksSam Ravnborg
Ingo Molnar reported that 'make randconfig' was not covering choice blocks properly, resulting in certain config options being left out of randconfig testing altogether. With the following patch we: - properly randomize choice value for normal choice blocks - properly randomize for multi choice blocks - added several comments to explain what is going on The root cause of the bug was that SYMBOL_VALID was set on the symbol representing the choice block so clearing this did the trick initially. But testign revealed a few more issues that is now fixed.

2009-03-07kbuild: fix 'make rpm' when CONFIG_LOCALVERSION_AUTO=y and using SCM treeJosh Hunt
Running 'make rpm' fails when CONFIG_LOCALVERSION_AUTO=y and using a kernel source tree under SCM. This is due to KERNELRELEASE being different when the initial make is run and when make is run from rpmbuild. mkspec creates kernel.spec using KERNELRELEASE: <mkspec> echo "%files" echo '%defattr (-, root, root)' echo "%dir /lib/modules" echo "/lib/modules/$KERNELRELEASE" echo "/lib/firmware" echo "/boot/*" echo "" </mkspec> When CONFIG_LOCALVERSION_AUTO=y scripts/setlocalversion is called and grabs any additional version info from SCM. Next, the srctree is tarred up and SCM information is excluded. rpmbuild reruns make and in the process generates a new include/config/kernel.release and thus a new KERNELRELEASE. However this time the SCM information is gone so KERNELRELEASE no longer has the additional version information. When "make modules_install" runs, it uses the new KERNELRELEASE value to determine where to install the modules. This conflicts with where the spec file assumes they are going because of the mis-matching KERNELRELEASE versions. <snippet> + INSTALL_MOD_PATH=/var/tmp/kernel-2.6.29rc4tip01479g5d85422-root + make -j16 modules_install INSTALL crypto/aead.ko INSTALL crypto/cbc.ko INSTALL crypto/chainiv.ko INSTALL crypto/crc32c.ko INSTALL crypto/crypto_algapi.ko INSTALL crypto/crypto_blkcipher.ko INSTALL crypto/crypto_hash.ko INSTALL crypto/cryptomgr.ko INSTALL crypto/ecb.ko INSTALL crypto/eseqiv.ko INSTALL crypto/krng.ko INSTALL crypto/md5.ko INSTALL crypto/pcbc.ko INSTALL crypto/rng.ko INSTALL drivers/block/cciss.ko INSTALL drivers/hid/hid-dummy.ko INSTALL drivers/scsi/iscsi_tcp.ko INSTALL drivers/scsi/libiscsi.ko INSTALL drivers/scsi/libiscsi_tcp.ko INSTALL drivers/scsi/scsi_transport_iscsi.ko INSTALL drivers/scsi/scsi_wait_scan.ko INSTALL fs/lockd/lockd.ko INSTALL fs/nfs/nfs.ko INSTALL fs/nfsd/nfsd.ko INSTALL lib/libcrc32c.ko INSTALL net/sunrpc/sunrpc.ko DEPMOD 2.6.29-rc4-tip + cp arch/x86/boot/bzImage /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/vmlinuz-2.6.29-rc4-tip-01479-g5d85422 + cp System.map /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/System.map-2.6.29-rc4-tip-01479-g5d85422 + cp .config /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/config-2.6.29-rc4-tip-01479-g5d85422 + cp vmlinux vmlinux.orig + bzip2 -9 vmlinux + mv vmlinux.bz2 /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/vmlinux-2.6.29-rc4-tip-01479-g5d85422.bz2 + mv vmlinux.orig vmlinux + /usr/lib/rpm/brp-compress Processing files: kernel-2.6.29rc4tip01479g5d85422-2 error: File not found: /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/lib/modules/2.6.29-rc4-tip-01479-g5d85422 RPM build errors: File not found: /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/lib/modules/2.6.29-rc4-tip-01479-g5d85422 make[1]: *** [rpm] Error 1 make: *** [rpm] Error 2 </snippet> I have tested this patch on git -tip, Linus' git tree, and the kernel.org tar files, both with and without CONFIG_LOCALVERSION_AUTO=y.

2009-01-07kconfig: add script to manipulate .config files on the command lineAndi Kleen
I often change single options in .config files. Instead of using an editor or one of the frontends it's convenient to do this from the command line. It's also useful to do from automated build scripts when building different variants from a base config file. I extracted most of the CONFIG manipulation code from one of my build scripts into a new shell script scripts/config The script is not integrated with the normal Kconfig machinery and doesn't do any checking against Kconfig files, but just manipulates that text format. This is always done at make time anyways. I believe this script would be a useful standard addition for scripts/* Sample usage: ./scripts/config --disable smp Disable SMP in .config file ./scripts/config --file otherdir/.config --module e1000e Enable E1000E as module in otherdir/.config ./scripts/config --state smp y Check state of config option CONFIG_SMP After merging into git please make scripts/config executable Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2009-01-07bootchart: improve output based on Dave Jones' feedbackArjan van de Ven
Dave Jones, in his blog, had some feedback about the bootchart script: Primarily his complaint was that shorter delays weren't visualized. The reason for that was that too small delays will have their labels mixed up in the graph in an unreadable mess. This patch has a fix for this; for one, it makes the output wider, so more will fit. The second part is that smaller delays are now shown with a much smaller font for the label; while this isn't per se readable at a 1:1 zoom, at least you can zoom in with most SVG viewing applications and see what it is you are looking at.

Then, I cd into <destdir>, run 'make modules_install' and get the error above. The issue turns out to be that we when we install firmware pick up the list of firmware blobs from firmware/Makefile. And this triggers the Makefile rules to update ihex2fw. There were two solutions for this issue: 1) Move the list of firmware blobs to a separate file 2) Avoid ihex2fw rebuild by moving it to scripts As I seriously beleive that the list of firmware blobs should be done in a fundamental different way solution 2) was selected.

2009-01-06checkpatch: struct file_operations should normally be constAndy Whitcroft
In the general use case struct file_operations should be a const object. Check for and warn where it is not. As suggested by Steven and Ingo.

2009-01-06checkpatch: ensure we actually detect if assignments split across linesAndy Whitcroft
When checking for assignments within if conditionals we check the whole of the condition, but the match is performed using a line constrained regular expression. This means we can miss split conditionals or those on the second line. Allow the check to span lines.

2009-01-06checkpatch: do not report nr_static as a static declarationAndy Whitcroft
Ensure we do not report identifiers containing the word static as static declarations.
