* pasemi_mac: Terminate PCI ID listolof@lixom.net2007-05-15
| | | | | | | | This caused some very interesting behaviour depending on what happened to be built at the same time. Add terminating empty entry to the list of IDs. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* pasemi_mac: Interrupt ack fixesOlof Johansson2007-05-15
| | | | | | | | | | | | Interrupt ack fixes Fix the packet count resets at interrupt time, using the cacheable packet count status to set number of processed/received packets, since the ack count is the cumulative number of packets processed, and not incremental.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | there is a wrong id in drivers/char/agp/via-agp.c #define PCI_DEVICE_ID_VIA_CX700 0x8324 It must be 0x0324 Notice that PCI_DEVICE_ID_VIA_CX700 is also used in drivers/i2c/busses/i2c-viapro.c and drivers/ide/pci/via82cxxx.c So, I think that constant must be renamed to avoid conflicting. I attached a proposed patch. Signed-off-by: Dave Jones <davej@redhat.com>

| * | [CPUFREQ] powernow-k7: fix MHz rounding issue with perflibDaniel Drake2007-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the PST tables are broken, powernow-k7 uses ACPI's processor_perflib to deduce the available frequency multipliers from the _PSS tables. Upon frequency change, processor_perflib performs some verification on the frequency (checks that it's within allowable bounds). powernow-k7 deals with absolute frequencies in KHz, whereas perflib only deals with MHz values. When performing the above verification, perflib multiplies the MHz values by 1000 to obtain the KHz value. We then end up with situations like the following: - powernow-k7 multiplies the multiplier by the FSB, and obtains a value such as 1266768 KHz - perflib belives the same state has frequency of 1266 MHz - acpi_processor_ppc_notifier calls cpufreq_verify_within_limits to verify that 1266768 is in the allowable range of 0 to 1266000 (i.e. 1266 * 1000) - it's not, so that frequency is rejected - the maximum CPU frequency is not reachable This patch solves the problem by rounding up the MHz values stored in perflib's tables. Additionally it corrects a broken URL. It also fixes http://bugzilla.kernel.org/show_bug.cgi?id=8255 although this case is a bit different: the frequencies in the _PSS tables are wildly wrong, but we get better results if we force ACPI to respect the fsb * multiplier calculations (even though it seems that the multiplier values aren't entirely correct either).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the presence of some running RX connections, we repeat queue_delayed_work calls each 4 RX WRs, which is a waste. It's enough to start stale task when a first passive connection is added, and rerun it every IPOIB_CM_RX_DELAY as long as there are outstanding passive connections.

But then a chip bug in the waldo series forced the use of a GPIO interrupt to signal packet reception. This greatly increased the frequency of GPIO interrupts which have the gpio_mask bits set on the waldo chips. Other bits in the gpio_status register are used for I2C clock and data lines, these bits are usually on. An "unlikely" annotation leftover from the old days was improperly applied to these bits, and an unnecessary chip mmio read was being accessed in the interrupt fast path on waldo. Remove the stagnant unlikely annotation in the interrupt handler and keep a shadow copy of the gpio_mask register to avoid the slow mmio read when testing for interruptable GPIO bits.

During the unlocked event delivery (to userspace) code, the poll callback can re-issue new events, and we must receive them correctly. Since we loop in a lockless fashion, we want to be O(nready), and we don't want to flash on/off the spinlock for every event, we have the poll callback to use a secondary list to queue events while we're inside the event delivery loop. The rw_semaphore has been turned into a mutex. This patch also adds the wait-exclusive flag, as suggested by Davi Arnaut.

* | | | Revert "ipmi: add new IPMI nmi watchdog handling"Linus Torvalds2007-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit f64da958dfc83335de1d2bef9d3868f30feb4e53. Andi Kleen is unhappy with the changes, and they really do not seem worth it. IPMI could use DIE_NMI_IPI instead of the new callback, even though that ends up having its own set of problems too, mainly because the IPMI code cannot really know the NMI was from IPMI or not. Manually fix up conflicts in arch/x86_64/kernel/traps.c and drivers/char/ipmi/ipmi_watchdog.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the device hits certain memory boundaries, it signals an interrupt and expects to be serviced. We don't need the feature but we need to make sure the device doesn't stall. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

The reason why these are not displayed in /proc/net/snmp is that some existing utilities are developed under the assumption which ipstat items in /proc/net/snmp is unchanged.
