| * cciss: disable DMA refetch on Smart Array P600Mike Miller (OS Dev)2007-10-171-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch disables DMA refetch in the PCI bridge. We have disabled DMA prefetch for quite some time. Testing with XEN revealed another ASIC bug. If dom0 resides on a P600 the board can can an MCA bi accessing invalid memory addresses. Apparently, we need to disable both prefetch and refetch. My understanding is a refetch operation should not occur but it is a valid thing to do if prefetched data is no longer available for whatever reason. Please consider this patch for inclusion.

* | | PNP: don't fail device init if no DMA channel availableJan Beulich2007-10-171-17/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most drivers for devices supporting ISA DMA can operate without DMA as well (falling back zo PIO). Thus it seems inappropriate for PNP to fail device initialization in case none of the possible DMA channels are available. Instead, it should be left to the driver to decide what to do if request_dma() fails. The patch at once adjusts the code to account for the fact that pnp_assign_dma() now doesn't need to report failure anymore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The floppy drive is slow. These days I see absolutely no good reason why the floppy driver should try to gain a tiny bit of speed by telling gcc to optimize access to some variables via the register keyword. Better to just leave gcc free to do whatever optimizations it deduces to be sane and not hamper it by telling it that some variables in the floppy driver are special and need to be fast (they don't).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an array is started read-only, MD_RECOVERY_NEEDED can be set but no recovery will be running. This causes 'sync_action' to report the wrong value. We could remove the test for MD_RECOVERY_NEEDED, but doing so would leave a small gap after requesting a sync action, where 'sync_action' would still report the old value. So make sure that for a read-only array, 'sync_action' always returns 'idle'.

I discovered this (and that the devices are added as disks/partitions are discovered at boot) while I was debugging why only one of my MD arrays would come up whole, while all the others were short a disk. I eventually discovered that it was enumerating through all of 9 of my 11 hds (2 had only 4 partitions apiece) while the other 9 have 15 partitions (I wanted 64 per drive...). The last partition of the 8th drive in my 9 drive raid 5 sets wasn't added, thus making the final md array short both a parity and data disk, and it was started later, elsewhere. This patch replaces that static array with a list. [akpm@linux-foundation.org: removed unused var] Signed-off-by: Michael J.

This is intended for drivers that support little or no hardware setting tty_termios_encode_baud_rate Allows you to set the input and output baud rate in a termios structure. A driver is supposed to set the resulting baud rate from a request so most will want to use this function to set the resulting input and output rates to match the hardware values. Internally it knows about keeping Bxxx encoding when possible to maximise compatibility. tty_encode_baud_rate As above but for the tty's own current termios structure I suspect this will initially need some tweaking as it gets enabled by driver patches over the next few mm cycles so consider this lot -mm only for the moment so it can stabilize and end up neat before it goes to base. I've tried not to break any obscure architectures - if you get a speed you can't represent the code will print warnings on non updated termios systems but not break. Once this is merged and seems sane I've got a growing pile of driver updates to use it - notably for USB serial drivers.

There are no plans to do anything about this piece of code and it does not fit anywhere anymore, so it is not just a matter of maintenance or the lack of. There are still some bits that might be added to the new lkkbd.c driver based on the old code, and the embedded hardware documentation which is otherwise quite hard to get hold of might be useful to keep too.

* | | add CONFIG_VT_UNICODEBill Nottingham2007-10-175-5/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of now, the kernel defaults to non-unicode and XLATE for the keyboard. We've been changing this in Fedora, but that requires patching the defaults in the kernel. The attached introduces CONFIG_VT_UNICODE, which sets the console in unicode mode by default on boot, including both the virtual terminal and the keyboard driver.

* | | cciss: fix error reporting for SG_IOSteve Cameron2007-10-171-18/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a problem with the way cciss was filling out the "errors" field of the request structure upon completion of requests. Previously, it just put a 1 or a 0 in there and used the negation of this as the uptodate parameter to one of the functions in the block layer, being a block device. For the SG_IO ioctl, this was not sufficient, and we noticed that, for example, sg_turs from sg3_utils did not correctly detect problems due to cciss having set rq->errors incorrectly.

* | | NBD: allow hung network I/O to be cancelledPaul Clements2007-10-171-31/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow NBD I/O to be cancelled when a network outage occurs. Previously, I/O would just hang, and if enough I/O was hung in nbd, the system (at least user-level) would completely hang until a TCP timeout (default, 15 minutes) occurred. The patch introduces a new ioctl NBD_SET_TIMEOUT that allows a transmit timeout value (in seconds) to be specified. Any network send that exceeds the timeout will be cancelled and the nbd connection will be shut down. I've tested with various timeout values and 6 seconds seems to be a good choice for the timeout. If the NBD_SET_TIMEOUT ioctl is not called, you get the old (I/O hang) behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes errors with utilities (such as LVM's vgscan) that try to scan all devices.

This may take a while... /dev/nbd0: read failed after 0 of 1024 at 0: Input/output error /dev/nbd0: read failed after 0 of 1024 at 509804544: Input/output error /dev/nbd0: read failed after 0 of 2048 at 0: Input/output error /dev/nbd1: read failed after 0 of 1024 at 509804544: Input/output error /dev/nbd1: read failed after 0 of 2048 at 0: Input/output error From now on, uninitialized nbd devices will have size zero, which prevents these errors.

The patch below goes further by just turning diacritics into unicode, hence providing better future support. The kbd support can be fetched from http://bugzilla.kernel.org/attachment.cgi?id=12313 This was tested in all of latin1, latin9, latin2 and unicode with french and czech dead keys. Turn the kernel accent_table into unicode, and extend ioctls KDGKBDIACR and KDSKBDIACR into their equivalents KDGKBDIACRUC and KDSKBDIACR. New function int conv_uni_to_8bit(u32 uni) for converting unicode into 8bit _input_. No, we don't want to store the translation, as it is potentially sparse and large.
