2011-02-04r8169: RxFIFO overflow oddities with 8168 chipsets.Francois Romieu1-9/+21
Some experiment-based action to prevent my 8168 chipsets locking-up hard in the irq handler under load (pktgen ~1Mpps). Apparently a reset is not always mandatory (is it at all ?). - RTL_GIGA_MAC_VER_12 - RTL_GIGA_MAC_VER_25 Missed ~55% packets. Note: - this is an old SiS 965L motherboard - the 8168 chipset emits (lots of) control frames towards the sender - RTL_GIGA_MAC_VER_26 The chipset does not go into a frenzy of mac control pause when it crashes yet but it can still be crashed.

The result is an infinite loop in interrupt handler as the RxFIFOOver is handled only for ...MAC_VER_11. With the workaround everything goes fine.

2011-02-04niu: Fix races between up/down and get_stats.David S. Miller1-16/+45
As reported by Flavio Leitner, there is no synchronization to protect NIU's get_stats method from seeing a NULL pointer in either np->rx_rings or np->tx_rings. In fact, as far as ->ndo_get_stats is concerned, these values are set completely asynchronously. Flavio attempted to fix this using a RW semaphore, which in fact works most of the time. However, dev_get_stats() can be invoked from non-sleepable contexts in some cases, so this fix doesn't work in all cases. So instead, control the visibility of the np->{rx,tx}_ring pointers when the device is being brough up, and use properties of the device down sequence to our advantage. In niu_get_stats(), return immediately if netif_running() is false. The device shutdown sequence first marks the device as not running (by clearing the __LINK_STATE_START bit), then it performans a synchronize_rcu() (in dev_deactive_many()), and then finally it invokes the driver ->ndo_stop() method. This guarentees that all invocations of niu_get_stats() either see netif_running() as false, or they see the channel pointers before ->ndo_stop() clears them out. If netif_running() is true, protect against startup races by loading the np->{rx,tx}_rings pointer into a local variable, and punting if it is NULL. Use ACCESS_ONCE to prevent the compiler from reloading the pointer on us. Also, during open, control the order in which the pointers and the ring counts become visible globally using SMP write memory barriers. We make sure the np->num_{rx,tx}_rings value is stable and visible before np->{rx,tx}_rings is. Such visibility control is not necessary on the niu_free_channels() side because of the RCU sequencing that happens during device down as described above. We are always guarenteed that all niu_get_stats calls are finished, or will see netif_running() false, by the time ->ndo_stop is invoked.

2011-02-04agp: ensure GART has an address before enabling itStephen Kitt1-11/+16
Some BIOSs (eg. the AMI BIOS on the Asus P4P800 motherboard) don't initialise the GART address, and pcibios_assign_resources() can ignore it because it can be marked as a host bridge (see https://bugzilla.kernel.org/show_bug.cgi?id=24392#c5 for details). This was handled correctly up to 2.6.35, but the pci_enable_device() cleanup in 2.6.36 96576a9e1a0cdb8 ("agp: intel-agp: do not use PCI resources before pci_enable_device()") means that the kernel tries to enable the GART before assigning it an address; in such cases the GART overlaps with other device assignments and ends up being disabled. This patch fixes https://bugzilla.kernel.org/show_bug.cgi?id=24392 Note that I imagine efficeon-agp.c probably has the same problem, but I can't test that and I'd like to make sure this patch is suitable for -stable (since 2.6.36 and 2.6.37 are affected).

2011-02-04Revert "agp: AMD AGP is used on UP1100 & UP1500 alpha boxen"Matt Turner1-1/+1
This reverts commit f191f144079b0083c6fa7d01a4acbd7263fb5032. The AMD 751 and 761 chipsets are used on the UP1000, UP1100, and UP1500 OEM motherboards, but they neglect to do anything to make AGP work. According to Ivan Kokshaysky: There is quite fundamental conflict between the Alpha architecture and x86 AGP implementation - Alpha is entirely cache coherent by design, while x86 AGP is not (I mean native AGP DMA transactions, not a PCI over AGP). There are no such things as non-cacheable mappings or software support for cache flushing/invalidation on Alpha, so x86 AGP code won't work on Nautilus. So there's no point in allowing this driver to be configured on Alpha. Signed-off-by: Matt Turner <mattst88@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
