2007-04-30cfq-iosched: development updateJens Axboe
- Implement logic for detecting cooperating processes, so we choose the best available queue whenever possible. - Improve residual slice time accounting. - Remove dead code: we no longer see async requests coming in on sync queues. That part was removed a long time ago. That means that we can also remove the difference between cfq_cfqq_sync() and cfq_cfqq_class_sync(), they are now indentical. And we can kill the on_dispatch array, just make it a counter. - Allow a process to go into the current list, if it hasn't been serviced in this scheduler tick yet. Possible future improvements including caching the cfqq lookup in cfq_close_cooperator(), so we don't have to look it up twice. cfq_get_best_queue() should just use that last decision instead of doing it again.

2007-04-30cfq-iosched: improve preemption for cooperating tasksJens Axboe
When testing the syslet async io approach, I discovered that CFQ sometimes didn't perform as well as expected. cfq_should_preempt() needs to better check for cooperating tasks, so fix that by allowing preemption of an equal priority queue if the recently queued request is as good a candidate for IO as the one we are currently waiting for.

2007-04-30[POWERPC] Remove dev_dbg redefinition in drivers/ps3/vuart.cPaul Mackerras
Commit 404d5b185b4eb56d6fa2f7bd27833f8df1c38ce4 changed the definition of dev_dbg in the !DEBUG case from being a #define to being a static inline. There was code in drivers/ps3/vuart.c to do exactly that, which fails to compile now. This fixes it by removing the redefinition, as the redefinition is now superfluous.

2007-04-30[POWERPC] Remove the unused HTDMSOUND driverAdrian Bunk
Recently, someone fixed a syntax error in the HTDMSOUND driver introduced 4 years ago. Unfortunately not by trying to compile this driver for his hardware but by code inspection - which seems to be a strong indication that there are no users left for this OSS sound driver. This patch therefore removes it.

2007-04-30[POWERPC] New registration for common Xilinx Virtex ppc405 platform devicesGrant Likely
Currently virtex support in mainline make use of the infrastructure in arch/ppc/syslib/ppc_sys.c for registering common devices on virtex ppc405 platforms. The ppc_sys.c code is not well suited to the dynamic nature of FPGA designs and makes adding new board ports more complex. This patch adds a new listing of common devices which does not depend on the ppc_sys.c infrastructure.

2007-04-30[POWERPC] Rework Kconfig dependancies for Xilinx Virtex ppc405 platformGrant Likely

Call only eth1394's own host reset handler from .tx_timeout, not the reset hooks of all other IEEE 1394 drivers.

2007-04-30ieee1394: eth1394: don't autoload by hotplug when ohci1394 startsStefan Richter
Until now, ieee1394 put an IP-over-1394 capability entry into each new host's config ROM. As soon as the controller was initialized --- i.e. right after modprobe ohci1394 --- this entry triggered a hotplug event which typically caused auto-loading of eth1394. This irritated or annoyed many users and distributors. Of course they could blacklist eth1394, but then ieee1394 wrongly advertized IP-over- 1394 capability to the FireWire bus. Therefore - remove the offending kernel config option IEEE1394_CONFIG_ROM_IP1394, - let eth1394 add the ROM entry by itself, i.e. only after eth1394 was loaded. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=7793 . To emulate the behaviour of older kernels, simply add the following to to /etc/modprobe.conf: install ohci1394 /sbin/modprobe eth1394; \ /sbin/modprobe --ignore-install ohci1394 Note, autoloading of eth1394 when an _external_ IP-over-1394 capable device is discovered is _not_ affected by this patch.
