| * | efivars: prevent oops on unload when efi is not enabledRandy Dunlap2011-05-061-2/+4

| * | driver: Google Memory ConsoleMike Waychison2011-04-293-0/+175
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the 'memconsole' driver. Our firmware gives us access to an in-memory log of the firmware's output. This gives us visibility in a data-center of headless machines as to what the firmware is doing. The memory console is found by the driver by finding a header block in the EBDA. The buffer is then copied out, and is exported to userland in the file /sys/firmware/log.

Currently, this driver only supports NVRAM and eventlog information. Deprecated functions have been removed from the driver, though their op-codes are left in place so that they are not re-used. This driver works by trampolining into the firmware via the smi_command outlined in the FADT table. Three protocols are used due to various limitations over time, but all are included herein. This driver should only ever load on Google boards, identified by either a "Google, Inc." board vendor string in DMI, or "GOOGLE" in the OEM strings of the FADT ACPI table. This logic happens in gsmi_system_valid().

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check for nonzero path in edd_has_edd30() has no sense. First, it looks at the wrong memory. Device path starts at offset 30 of the info->params structure which is at offset 8 from the beginning of info structure, but code looks at info + 4 instead. This was correct when code was introduced, but around v2.6.4 three more fields were added to edd_info structure (commit 66b61a5c in history.git). Second, even if it will check correct memory it will always succeed since at offset 30 (params->key) there will be non-zero values otherwise previous check would fail. The patch replaces this bogus check with one that verifies checksum. Signed-off-by: Gleb Natapov <gleb@redhat.com> Link: http://lkml.kernel.org/r/20110426082132.GG2265@redhat.com Signed-off-by: H.

When we added support for boot, the anaconda team and I were using older firmware (I guess 4 years old), so boot does not work on current cards. This patch modifies the ibft search code to search for "BIFT" along with the other possible values. Broadcom has tested the patch and reported it works with their firmware. Mike has tested Chelsio and Intel cards.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dcdbas driver can do an I/O write to cause a SMI to occur. The SMI handler looks at certain registers and memory locations, so the SMI needs to happen immediately. On some systems I/O writes are posted, though, causing the SMI to happen well after the "outb" occurred, which causes random failures. Following the "outb" with an "inb" forces the write to go through even if it is posted.

This means that the struct dmi_header passed to callbacks from dmi_walk() itself isn't byte aligned. This causes problems on architectures that expect aligned data, such as IA64. The dmi-sysfs patchset introduced structure member accesses through this passed in dmi_header. Fix this by memcpy()ing the structures to temporary locations on stack when inspecting/copying them.

Entries are enumerated via dmi_walk() on module load, and are populated as kobjects rooted at /sys/firmware/dmi/entries. Entries are named "<type>-<instance>", where: <type> : is the type of the entry, and <instance> : is the ordinal count within the DMI table of that entry type. This instance is used in lieu the DMI entry's handle as no assurances are made by the kernel that handles are unique. All entries export the following attributes: length : The length of the formatted portion of the entry handle : The handle given to this entry by the firmware raw : The raw bytes of the entire entry, including the formatted portion, the unformatted (strings) portion, and the two terminating nul characters. type : The DMI entry type instance : The ordinal instance of this entry given its type. position : The position ordinal of the entry within the table in its entirety. Entries in dmi-sysfs are kobject backed members called "struct dmi_sysfs_entry" and belong to dmi_kset. They are threaded through entry_list (protected by entry_list_lock) so that we can find them at cleanup time.

* / kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-201-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

* | include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-307-2/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
