2005-05-18[TG3]: In tg3_poll(), resample status_tag after doing work.David S. Miller

2005-05-18[TG3]: Refine DMA boundary setting.David S. Miller
Extract DMA boundary bit selection into a seperate function, tg3_calc_dma_bndry(). Call this from tg3_test_dma(). Make DMA test more reliable by using no DMA boundry setting during the test. If the test passes, then use the setting we selected before the test. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Michael Chan <mchan@broadcom.com>
2005-05-18[TG3]: Set minimal hw interrupt mitigation.David S. Miller
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>
2005-05-18[TG3]: Add tagged status support.David S. Miller
When supported, use the TAGGED interrupt processing support the chip provides. 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. Miller <davem@davemloft.net>

2005-05-18[PATCH] Fix filp being passed through raw ioctl handlerStephen Tweedie
Don't pass meaningless file handles to block device ioctls. The recent raw IO ioctl-passthrough fix started passing the raw file handle into the block device ioctl handler. That's unlikely to be useful, as the file handle is actually open on a character-mode raw device, not a block device, so dereferencing it is not going to yield useful results to a block device ioctl handler. Previously we just passed NULL; also not a value that can usefully be dereferenced, but at least if it does happen, we'll oops instead of silently pretending that the file is a block device, so NULL is the more defensive option here. This patch reverts to that behaviour. Noticed by Al Viro.

2005-05-17[PATCH] Driver Core: remove driver model detach_stateDavid Brownell
The driver model has a "detach_state" mechanism that: - Has never been used by any in-kernel drive; - Is superfluous, since driver remove() methods can do the same thing; - Became buggy when the suspend() parameter changed semantics and type; - Could self-deadlock when called from certain suspend contexts; - Is effectively wasted documentation, object code, and headspace. This removes that "detach_state" mechanism; net code shrink, as well as a per-device saving in the driver model and sysfs.

2005-05-17[PATCH] Driver Core: pm diagnostics update, check for errorsDavid Brownell
This patch includes various tweaks in the messaging that appears during system pm state transitions: * Warn about certain illegal calls in the device tree, like resuming child before parent or suspending parent before child. This could happen easily enough through sysfs, or in some cases when drivers use device_pm_set_parent(). * Be more consistent about dev_dbg() tracing ... do it for resume() and shutdown() too, and never if the driver doesn't have that method. * Say which type of system sleep state is being entered. Except for the warnings, these only affect debug messaging.

2005-05-17[PATCH] PCI Hotplug: CPCI updateScott Murray
[PATCH] CPCI: update I have finally done some work to update the CompactPCI hotplug driver to fix some of the outstanding issues in 2.6: - Added adapter and latch status ops so that those files will get created by the current PCI hotplug core. This used to not be required, but seems to be now after some of the sysfs rework in the core. - Replaced slot list spinlock with a r/w semaphore to avoid any potential issues with sleeping. This quiets all of the runtime warnings. - Reworked interrupt driven hot extraction handling to remove need for a polling operator for ENUM# status. There are a lot of boards that only have an interrupt driven by ENUM#, so this lowers the bar to entry. - Replaced pci_visit_dev usage with better use of the PCI core functions. The new code is functionally equivalent to the previous code, but the use of pci_enable_device on insert needs to be investigated further, as I need to do some more testing to see if it is still necessary.
