| * [PATCH] ppc64: Fix booting on latest G5 modelsBenjamin Herrenschmidt2005-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The latest speedbumped Apple G5 models have a "bug" in the Open Firmware device tree that lacks the proper interrupt routing information for the northbridge i2c controller. Apple's driver silently falls back into a sub-optimal "polled" mode (heh, maybe they didn't even notice the bug because of that :), our driver didn't properly check and crashes :( This patch fixes our driver to not crash, and adds code to the prom_init() OF trampoline code that detects the "bug" and adds the missing information back for this chipset revision. This fixes booting and thermal control on these models. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | * [SCSI] aic7xxx: fix U160 modeJames Bottomley2005-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new period/dt setting routines don't get the coupling of these parameters correct. This means that Domain Validation never gets DT set, and thus the drive gets restricted to U80. Fix this by restoring the couplings in the set routines.

Currently it's rather fancifully refcounted in the queuecommand callback. This patch moves allocation and destroy to their correct places in slave_alloc/slave_destory. Now we can guarantee that everywhere a device is requested, it's actually been allocated, so don't check for this anymore. Additionally, the per device busy timer was the only source of potential use after free. It's been deleted because Linux does the correct thing with busy returns, so there's no need to implement a separate timer in the driver. Finally, implement code that forces all the device parameters to zero (i.e. async and narrow) in the slave alloc, inform the spi class of the bios recorded maximums and wait until slave configure before trying anything more adventurous.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The aic7xxx driver has two spurious queues in it's linux glue code: the busyq which queues incoming commands to the driver and the completeq which queues finished commands before sending them back to the mid-layer This patch just removes the busyq and makes the aic finally return the correct status to get the mid-layer to manage its queueing, so a command is either committed to the sequencer or returned to the midlayer for requeue.

| | * [SCSI] implement parameter limits in the SPI transport classJames Bottomley2005-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a basic need not to have parameters go under or over certain values when doing domain validation. The basic ones are max_offset, max_width and min_period This patch makes the transport class take and enforce these three limits. Currently they can be set by the user, although they could obviously be read from the HBA's on-board NVRAM area during slave_configure (if it has one).

| * | [PATCH] packet driver permission checking fixPeter Osterlund2005-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you tried to open a packet device first in read-only mode and then a second time in read-write mode, the second open succeeded even though the device was not correctly set up for writing. If you then tried to write data to the device, the writes would fail with I/O errors. This patch prevents that problem by making the second open fail with -EBUSY.

| * | [TG3]: Set minimal hw interrupt mitigation.David S. Miller2005-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even though we do software interrupt mitigation via NAPI, it still helps to have some minimal hw assisted mitigation. This helps, particularly, on systems where register I/O overhead is much greater than the CPU horsepower. For example, it helps on NUMA systems. In such cases the PIO overhead to disable interrupts for NAPI accounts for the majority of the packet processing cost. The CPU is fast enough such that only a single packet is processed by each NAPI poll call. Thanks to Michael Chan for reviewing this patch. Signed-off-by: David S. Miller <davem@davemloft.net>
| * | [TG3]: Add tagged status support.David S. Miller2005-05-19

In this mode, instead of a "on/off" binary semaphore, an incrementing tag scheme is used to ACK interrupts. All MSI supporting chips support TAGGED mode, so the tg3_msi() interrupt handler uses it unconditionally. This invariant is verified when MSI support is tested. Since we can invoke tg3_poll() multiple times per interrupt under high packet load, we fetch a new copy of the tag value in the status block right before we actually do the work. Also, because the tagged status tells the chip exactly which work we have processed, we can make two optimizations: 1) tg3_restart_ints() need not check tg3_has_work() 2) the tg3_timer() need not poke the chip 10 times per second to keep from losing interrupt events Based upon valuable feedback from Michael Chan <mchan@broadcom.com> Signed-off-by: David S.
