2005-11-18[PATCH] intel ixp2000 network driverLennert Buytenhek
The way the hardware and firmware work is that there is one shared RX queue and IRQ for a number of different network interfaces. Due to this, we would like to process received packets for every interface in the same NAPI poll handler, so we need a pseudo-device to schedule polling on. What the driver currently does is that it always schedules polling for the first network interface in the list, and processes packets for every interface in the poll handler for that first interface -- however, this scheme breaks down if the first network interface happens to not be up, since netif_rx_schedule_prep() checks netif_running(). sky2 apparently has the same issue, and Stephen Hemminger suggested a way to work around this: create a variant of netif_rx_schedule_prep() that does not check netif_running(). I implemented this locally and called it netif_rx_schedule_prep_notup(), and it seems to work well, but it's something that probably not everyone would be happy with. The ixp2000 is an ARM CPU with a high-speed network interface in the CPU itself (full duplex 4Gb/s or 10Gb/s depending on the IXP model.) The CPU package also contains 8 or 16 (again depending on the IXP model) 'microengines', which are somewhat primitive but very fast and efficient processor cores which can be used to offload various things from the main CPU. This driver makes the high-speed network interface in the CPU visible and usable as a regular linux network device. Currently, it only supports the Radisys ENP2611 IXP board, but adding support for other board types should be fairly easy.

2005-11-18[PATCH] md: fix is_mddev_idle calculation now that disk/sector accounting ↵NeilBrown
happens when request completes md needs to monitor the rate of requests to its devices when doing resync/recovery so that it can back-off when there is non-resync IO. It does this by comparing resync IO, which it counts, with total IO which is taken from disk_stats. disk_stats were recently changed to account sectors when a request completes instead of when it is queued. This upsets md's calculations. We could do the sync_io accounting at the end of requests too, but that has problems. If an underlying device is an md array, the accounting will still be done when the request is submitted. This could be changed for some raid levels, but it cannot be changed for raid0 or linear without substantial code changes. So instead, we increase the error that is_mddev_idle allows, up to the maximum amount of resync IO that can be in flight at any time. The calculation is current fragile as each personality as different limits for in-flight resync. This should be fixed up. For now, this simple patch fixes the problem. Increasing the error margin decreases the sensitivity to non-resync IO. To partially compensate for this, the time to wait when non-resync IO is detected is increased so that less steady IO is required to keep the resync at bay.

2005-11-18[PATCH] add success/failure indication to RCU torture testPaul E. McKenney

This patch adds a "SUCCESS"/"FAILURE" string to the line that flags the end of the test, where it can easily be seen with "dmesg | tail" at the end of the test.

2005-11-18powerpc: Fix delay functions for 601 processorsPaul Mackerras
My earlier merge of delay.h introduced a timebase-based udelay for 32-bit machines but also broke the 601, which doesn't have the timebase register. This fixes it by using the 601's RTC register on the 601, and also moves __delay() and udelay() to be out-of-line in arch/powerpc/kernel/time.c. These functions aren't really performance critical, after all. Signed-off-by: Paul Mackerras <paulus@samba.org>

Noticed by Olaf Hering.
