* MTD: Add lock/unlock operations for Atmel AT49BV6416Haavard Skinnemoen2006-08-16
| | | | | | | | | | | | | | The AT49BV6416 is locked by default, so we really need to provide at least the unlock() operation for write and erase to work. This patch implements both ->lock() and ->unlock() and provides a fixup to install them when an AT49BV6416 chip is detected. These functions are probably valid on more Atmel chips, but I believe it's mostly obsolete ones. The AT49BV6416 is in fact obsolete, but it's used on all current AT32STK1000 development boards.

* MTD: Convert Atmel PRI information to AMD formatHaavard Skinnemoen2006-08-16
| | | | | | | | | | | | Atmel flash chips don't have PRI information in the same format as AMD flash chips. This patch installs a fixup for all Atmel chips that converts the relevant PRI fields into AMD format. Only the fields that are actually used by the command set is actually converted. The rest are initialized to zero (which should be safe) Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Signed-off-by: Josh Boyer <jwboyer@gmail.com>

* [MTD] Fixes of performance and stability issues in CFI driver.Alexey Korolev2006-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix of performance and stability issues on Intel NOR chips. It fixes: 1. Very low write performance on Sibley (perf tests demonstrated write performance less than 100Kb/sec when it should be over 400Kb/sec). 2. Low erase performance. (perf tests on Sibleuy demonstrated erase performance 246Kb/sec when it should be over 300Kb/sec). 3. Error on JFFS2 tests with CPU loading application when MTD returns "block erase error: (status timeout)" To fix the issue it does the following: 1. Removes the timeout tuning from inval_cache_and_wait_for_operation. 2. Waiting conditions in inval_cache_and_wait_for_operation now is based on timer resolution If timeout is lower than timer resolution then we do in cycle "Checking the status" udelay(1); cond_resched(); If timeout is greater than timer resolution (probably erase operation) We do the following sleep for half of operation timeout and do in cycle the following "Checking the status" sleep for timer resolution Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Alexey Korolev <akorolev@infradead.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* block2mtd.c: Make kernel boot command line arguments work (try 4)Ville Herva2006-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Trying to pass kernel command line arguments to block2mtd at boot-time does not work currently. block2mtd_setup() is called so early that kmalloc() fails nevermind being able to do open_bdev_excl() (which requires rootfs to be mounted. This patch only saves the option string at the early boot stage, and parses them later when block2mtd_init() is called. If open_bdev_excl() fails, open_by_devnum(name_to_dev_t()) is tried instead, which makes it possible to initialize the driver before rootfs has been mounted. Also gets rid of the superfluous parse_name() that only checks if name is longer than 80 chars and copies it to a string that is not kfreed. With this patch, I can boot statically compiled block2mtd, and mount jffs2 as rootfs (without modules or initrd), with lilo config like this: root=/dev/mtdblock0 append="rootfstype=jffs2 block2mtd.block2mtd=/dev/hdc2,65536" (Note that rootfstype=jffs2 is required, since the kernel only tries filesystems without "nodev" attribute by default, and jffs is "nodev"). Compared to first version of this patch, this one does not copy the parameters to the global buffer if init has already been called, and the global array is marked as __initdata. Compared to the second version of this patch, module build is fixed. Compared to the third version of this patch, statically compiled block2mtd driver with no boot-time parameter no longer gives spurious error 'cannot open device ""' Signed-off-by: Ville Herva <vherva@vianova.fi> Acked-by: Jörn Engel <joern@wohnheim.fh-wedel.de> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

* | | [PATCH] Fix copying of pgdat array on each node for ia64 memory hotplugYasunori Goto2006-07-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I found a bug in memory hot-add code for ia64. IA64's code has copies of pgdat's array on each node to reduce memory access over crossing node. This array is used by NODE_DATA() macro. When new node is hot-added, this pgdat's array should be updated and copied on new node too. However, I used for_each_online_node() in scatter_node_data() to copy it. This meant its array is not copied on new node. Because initialization of structures for new node was halfway, so online_node_map couldn't be set at this time. To copy arrays on new node, I changed it to check value of pgdat_list[] which is source array of copies. I tested this patch with my Memory Hotadd emulation on Tiger4. This patch is for 2.6.17-git20.
