This matters for some controllers and in one or two cases almost doubles PIO performance. Add a bmdma32 operations set we can inherit and activate it for some controllers Signed-off-by:

There is an issue in ATI SB600/SB700 SATA that PxSERR.E should not be set on some conditions, which will lead to many SATA ODD error messages. commit 55a61604 is the workaround. Since SB800 fixed this HW issue, IGN_SERR_INTERNAL should be withdrawn for SB800. Signed-off-by:

Reimplement mode programming logic of pata_hpt366 such that it's identical to that of IDE hpt366 driver. The differences were... * pata_hpt366 used 0xCFFF8FFFF to mask pio modes and 0x3FFFFFFF dma modes. IDE hpt366 uses 0xC1F8FFFF for PIO, 0x303800FF for MWDMA and 0x30070000 for UDMA. * pata_hpt366 doesn't set 0x08000000 for PIO unless it's already set and always turns it on for MWDMA/UDMA. IDE hpt366 doesn't bother with the bit. It always uses what was there. * IDE hpt366 always clears 0xC0000000. pata_hpt366 doesn't. Signed-off-by:

Certain ACPI implementations mess up IOCFG on _STM making libata detect cable type incorrectly after a suspend/resume cycle. This patch makes ata_piix save IOCFG on attach, use the saved value for things which aren't dynamic and restore it on detach so that the next driver also gets the BIOS initialized value. This patch contains the following changes. * makes ich_pata_cable_detect() use saved_iocfg. * make piix_iocfg_bit18_quirk() take @host and use saved_iocfg. * hpriv allocation moved upwards to save iocfg before doing anything else. This fixes bz#11879. Andreas Mohr reported and diagnosed the problem. Signed-off-by:

turns out that there are real problems with allowing async tasks that are scheduled from async tasks to run after the async_synchronize_full() returns. This patch makes the _full more strict and a complete synchronization. Later I might need to add back a lighter form of synchronization for other uses.. but not right now. Signed-off-by:

Remove the saved_max_pfn check from the /proc/vmcore function read_from_oldmem(). No need to verify, we should be able to just trust that "elfcorehdr=" is correctly passed to the crash kernel on the kernel command line like we do with other parameters. The read_from_oldmem() function in fs/proc/vmcore.c is quite similar to read_from_oldmem() in drivers/char/mem.c, but only in the latter it makes sense to use saved_max_pfn. For oldmem it is used to determine when to stop reading. For vmcore we already have the elf header info pointing out the physical memory regions, no need to pass the end-of- old-memory twice. Removing the saved_max_pfn check from vmcore makes it possible for architectures to skip oldmem but still support crash dump through vmcore - without the need for the old saved_max_pfn cruft. Architectures that want to play safe can do the saved_max_pfn check in copy_oldmem_page(). Not sure why anyone would want to do that, but that's even safer than today - the saved_max_pfn check in vmcore removed by this patch only checks the first page. Signed-off-by:

Evgeniy Polyakov authored
This small patchset extendes existing commands with reset, master IO and status messages. Reset is used to reset the bus for given master device, master IO command allows to initiate IO against bus itself not selecting slave device first, which can be used to probe the device for example. And status messages carry command completion status back to the userspace (namely very useful to get -ENODEV from when requested device was not found). Great thanks to Paul Alfille of OWFS for testing and commands suggestions. This patch: Allow starting of IO not against already found slave devices, but against the bus itself, which can be used for example to probe devices.

Initiates search (or alarm search) and returns all found devices to userspace. Found devices are not added into the system (i.e. they are not attached to family devices or bus masters), it will be done via (if was not done yet) usual timed searching. Signed-off-by:

Evgeniy Polyakov authored
This patch series introduces and extends several userspace commands used with netlink protocol. Touch block command allows to write data and return sampled data to the userspace. Extended search and alarm seach commands to return list of slave devices found during given search. List masters command allows to send all registered master IDs to the userspace. Great thanks to Paul Alfille (owfs) who tested this implementation and wrote w1-to-network daemon http://sourceforge.net/projects/w1repeater/ and Frederik Deweerdt and Randy Dunlap for review.
