* V4L/DVB (5323): Updated support for tuner callbacksHartmut Hackmann2007-04-27
| | | | | | | | | | | | This change supplies a more generic version of the tuner callback. The tuner struct now has a function pointer int (*tuner_callback) (void *dev, int command, int arg) additionally to a int config parameter. both can be set through the TUNER_SET_TYPE_ADDR client call. Note that the meaning of the parameters depend on the tuner type. Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

| | | | | | | | | | | | | These entries mainly are to support configurations of the tda827x silicon tuner with a preamplifier. The values can be set throgh the attach inform or through the extended TUNER_SET_TYPE_ADDR client call. The function pointer will only be updated if the parameter is not NULL. Since a typecast is necessary to set the pointer, i added a typedef for this pointer (tuner_gpio_func_t) in tuner.h Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* make SysRq-T show all tasks againIngo Molnar2007-04-27
| | | | | | | | | | | | | | | show_state() (SysRq-T) developed the buggy habbit of not showing TASK_RUNNING tasks. This was due to the mistaken belief that state_filter == -1 would be a pass-through filter - while in reality it did not let TASK_RUNNING == 0 p->state values through. Fix this by restoring the original '!state_filter means all tasks' special-case i had in the original version. Test-built and test-booted on i686, SysRq-T now works as intended.

UBI provides a flexible partitioning concept which still allows for wear-levelling across the whole flash device. In a sense, UBI may be compared to the Logical Volume Manager (LVM). Whereas LVM maps logical sector numbers to physical HDD sector numbers, UBI maps logical eraseblocks to physical eraseblocks. More information may be found at http://www.linux-mtd.infradead.org/doc/ubi.html Partitioning/Re-partitioning An UBI volume occupies a certain number of erase blocks. This is limited by a configured maximum volume size, which could also be viewed as the partition size. Each individual UBI volume's size can be changed independently of the other UBI volumes, provided that the sum of all volume sizes doesn't exceed a certain limit. UBI supports dynamic volumes and static volumes. Static volumes are read-only and their contents are protected by CRC check sums. Bad eraseblocks handling UBI transparently handles bad eraseblocks. When a physical eraseblock becomes bad, it is substituted by a good physical eraseblock, and the user does not even notice this. Scrubbing On a NAND flash bit flips can occur on any write operation, sometimes also on read. If bit flips persist on the device, at first they can still be corrected by ECC, but once they accumulate, correction will become impossible. Thus it is best to actively scrub the affected eraseblock, by first copying it to a free eraseblock and then erasing the original. The UBI layer performs this type of scrubbing under the covers, transparently to the UBI volume users. Erase Counts UBI maintains an erase count header per eraseblock. This frees higher-level layers (like file systems) from doing this and allows for centralized erase count management instead. The erase counts are used by the wear-levelling algorithm in the UBI layer. The algorithm itself is exchangeable. Booting from NAND For booting directly from NAND flash the hardware must at least be capable of fetching and executing a small portion of the NAND flash. Some NAND flash controllers have this kind of support. They usually limit the window to a few kilobytes in erase block 0. This "initial program loader" (IPL) must then contain sufficient logic to load and execute the next boot phase. Due to bad eraseblocks, which may be randomly scattered over the flash device, it is problematic to store the "secondary program loader" (SPL) statically. Also, due to bit-flips it may become corrupted over time. UBI allows to solve this problem gracefully by storing the SPL in a small static UBI volume. UBI volumes vs. static partitions UBI volumes are still very similar to static MTD partitions: * both consist of eraseblocks (logical eraseblocks in case of UBI volumes, and physical eraseblocks in case of static partitions; * both support three basic operations - read, write, erase. But UBI volumes have the following advantages over traditional static MTD partitions: * there are no eraseblock wear-leveling constraints in case of UBI volumes, so the user should not care about this; * there are no bit-flips and bad eraseblocks in case of UBI volumes. So, UBI volumes may be considered as flash devices with relaxed restrictions. Where can it be found? Documentation, kernel code and applications can be found in the MTD gits. What are the applications for? The applications help to create binary flash images for two purposes: pfi files (partial flash images) for in-system update of UBI volumes, and plain binary images, with or without OOB data in case of NAND, for a manufacturing step. Furthermore some tools are/and will be created that allow flash content analysis after a system has crashed.. Who did UBI? The original ideas, where UBI is based on, were developed by Andreas Arnez, Frank Haverkamp and Thomas Gleixner. Josh W. Boyer and some others were involved too. The implementation of the kernel layer was done by Artem B. Bityutskiy. The user-space applications and tools were written by Oliver Lohmann with contributions from Frank Haverkamp, Andreas Arnez, and Artem. Joern Engel contributed a patch which modifies JFFS2 so that it can be run on a UBI volume. Thomas Gleixner did modifications to the NAND layer. Alexander Schmidt made some testing work as well as core functionality improvements. Signed-off-by: Artem B. Bityutskiy <dedekind@linutronix.de> Signed-off-by: Frank Haverkamp <haver@vnet.ibm.com>

| * | [PATCH] Turn do_sync_file_range() into do_sync_mapping_range()Mark Fasheh2007-04-26
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | do_sync_file_range() accepts a file * from which it takes an address_space to sync. Abstract out the bulk of the function into do_sync_mapping_range() which takes the address_space directly. This way callers who want to sync an address_space directly can take advantage of the functionality provided. do_sync_file_range() is preserved as a small wrapper around do_sync_mapping_range(). Ocfs2 in particular would like to use this to initiate a sync of a specific inode range during truncate, where a file * may not be available.

A lot of cleanups fell out of this. For example, the get_compare() tick_op was totally unused, so was deleted. And the most often used tick_op members were grouped together for cache-friendlyness. The sparc64 TSC is given to the kernel as a one-shot timer. tick_ops->init_timer() simply turns off the privileged bit in the tick register (when possible), and disables the interrupt by setting bit 63 in the compare register. The ->disable_irq() op also sets this bit. tick_ops->add_compare() is changed to: 1) Add the given delta to "tick" not to "compare" 2) Return a boolean which, if true, means that the tick value read after writing the compare value was found to have incremented past the initial tick value. This mirrors logic used in the HPET driver's ->next_event() method. Each tick_ops implementation also now provides a name string. And we feed this into the clocksource and clockevents layers.
