2012-09-25NFC: Queue pn533 commandsSamuel Ortiz
Instead of returning EBUSY when getting a command while another one is running, we queue them. Upon completion of the pending command, the next one is processed. Besides the fact that it simplifies the pn533 locking scheme, it also comes with the nice side effect of fixing the following warning: [ 82.274297] ===================================== [ 82.274297] [ BUG: bad unlock balance detected! ] [ 82.274298] 3.5.0-rc1+ #1 Not tainted [ 82.274299] ------------------------------------- [ 82.274300] kworker/u:1/16 is trying to release lock (&dev->cmd_lock) at: [ 82.274305] [<ffffffff8144f246>] mutex_unlock+0x9/0xb [ 82.274305] but there are no more locks to release!

2012-09-24PCI: acpiphp: Handle PCIe ports without native hotplug capabilityJiang Liu
Commit 0d52f54e2ef64c189dedc332e680b2eb4a34590a (PCI / ACPI: Make acpiphp ignore root bridges using PCIe native hotplug) added code that made the acpiphp driver completely ignore PCIe root complexes for which the kernel had been granted control of the native PCIe hotplug feature by the BIOS through _OSC. Later commit 619a5182d1f38a3d629ee48e04fa182ef9170052 "PCI hotplug: Always allow acpiphp to handle non-PCIe bridges" relaxed the constraints to allow acpiphp driver handle non-PCIe bridges under such a complex. The constraint needs to be relaxed further to allow acpiphp driver to handle PCIe ports without native PCIe hotplug capability. Some MR-IOV switch chipsets, such PLX8696, support multiple virtual PCIe switches and may migrate downstream ports among virtual switches. To migrate a downstream port from the source virtual switch to the target, the port needs to be hot-removed from the source and hot-added into the target. The pciehp driver can't be used here because there are no slots within the virtual PCIe switch. So acpiphp driver is used to support downstream port migration. A typical configuration is as below: [Root without native PCIe HP] [Upstream port of vswitch without native PCIe HP] [Downstream port of vswitch with native PCIe HP] [PCIe endpoint] Here acpiphp driver will be used to handle root ports and upstream port in the virtual switch, and pciehp driver will be used to handle downstream ports in the virtual switch.

2012-09-24PCI/ACPI: Use acpi_driver_data() rather than searching acpi_pci_rootsTaku Izumi
This patch changes the implementation of acpi_pci_find_root(). We can access acpi_pci_root without scanning acpi_pci_roots list. If hostbridge hotplug is supported, acpi_pci_roots list will be protected by mutex. We should not access acpi_pci_roots list if preventable to lessen deadlock risk.

This patch changes the function signature of walk_root_bridge(). We can omit _STA, _SEG, and _BBN evaluation by passing not acpi_handle but acpi_pci_root. Now that acpi_pci_slot_add() which is the only caller of walk_root_bridge() gets acpi_pci_root structure, changing signature of walk_root_bridge() is reasonable.

2012-09-24PCI/ACPI: Pass acpi_pci_root to acpi_pci_drivers' add/remove interfaceTaku Izumi
This patch changes .add/.remove interfaces of acpi_pci_driver. In the current implementation acpi_handle is passed as a parameter of .add/.remove interface. However, the acpi_pci_root structure contains more useful information than just the acpi_handle. This enables us to avoid some useless lookups in each acpi_pci_driver. Note: This changes interfaces used by acpi_pci_register_driver(), an exported symbol. This patch updates all the in-kernel users, but any out-of-kernel acpi_pci_register_driver() users will need updates.

2012-09-24net: use a per task frag allocatorEric Dumazet
We currently use a per socket order-0 page cache for tcp_sendmsg() operations. This page is used to build fragments for skbs. Its done to increase probability of coalescing small write() into single segments in skbs still in write queue (not yet sent) But it wastes a lot of memory for applications handling many mostly idle sockets, since each socket holds one page in sk->sk_sndmsg_page Its also quite inefficient to build TSO 64KB packets, because we need about 16 pages per skb on arches where PAGE_SIZE = 4096, so we hit page allocator more than wanted. This patch adds a per task frag allocator and uses bigger pages, if available. An automatic fallback is done in case of memory pressure. (up to 32768 bytes per frag, thats order-3 pages on x86) This increases TCP stream performance by 20% on loopback device, but also benefits on other network devices, since 8x less frags are mapped on transmit and unmapped on tx completion. Alexander Duyck mentioned a probable performance win on systems with IOMMU enabled. Its possible some SG enabled hardware cant cope with bigger fragments, but their ndo_start_xmit() should already handle this, splitting a fragment in sub fragments, since some arches have PAGE_SIZE=65536 Successfully tested on various ethernet devices.

2012-09-24gianfar: Change default HW Tx queue scheduling modeClaudiu Manoil
This is primarily to address transmission timeout occurrences, when multiple H/W Tx queues are being used concurrently. Because in the priority scheduling mode the controller does not service the Tx queues equally (but in ascending index order), Tx timeouts are being triggered rightaway for a basic test with multiple simultaneous connections like: iperf -c <server_ip> -n 100M -P 8 resulting in kernel trace: NETDEV WATCHDOG: eth1 (fsl-gianfar): transmit queue <X> timed out ------------[ cut here ]------------ WARNING: at net/sched/sch_generic.c:255 ... and controller reset during intense traffic, and possibly further complications. This patch changes the default H/W Tx scheduling setting (TXSCHED) for multi-queue devices, from priority scheduling mode to a weighted round robin mode with equal weights for all H/W Tx queues, and addresses the issue above.

2012-09-24net: loopback: set default mtu to 64KEric Dumazet
loopback current mtu of 16436 bytes allows no more than 3 MSS TCP segments per frame, or 48 Kbytes. Changing mtu to 64K allows TCP stack to build large frames and significantly reduces stack overhead. Performance boost on bulk TCP transferts can be up to 30 %, partly because we now have one ACK message for two 64KB segments, and a lower probability of hitting /proc/sys/net/ipv4/tcp_reordering default limit.

The KSZ8021 PHY was previously caught by KS8051, which is not correct. This PHY needs additional setup if it is strapped for address 0. In such case an reserved bit must be written in the 0x16, "Operation Mode Strap Override" register. According to the KS8051 datasheet, that bit means "PHY Address 0 in non-broadcast" and it indeed behaves as such on KSZ8021. The issue where the ethernet controller (Freescale FEC) did not communicate with network is fixed by writing this bit as 1. Signed-off-by: Marek Vasut <marex@denx.de> Cc: David J.

when __ARCH_HAS_VGA_DEFAULT_DEVICE is not defined, aka EFIFB is not used, for static path, vga_default setting is through vga_arbiter_add_pci_device. and later x86 pci_fixup_video, will skip setting again. - subsys_initcall(vga_arb_device_init) come first to call vga_arbiter_add_pci_device. It will call pci_get_dev to hold one reference. for hotplug add path, even vga_arbiter_add_pci_device is called via notifier, but it will check VGA_RSRC_LEGACY_MASK that is not set for hotplug path. So x86 pci_fixup_video will take over to call vga_set_default_device(). It will not hold one refrence. Later for hotplug remove path, vga_arbiter_del_pci_device that does not check VGA_RSRC_LEGACY_MASK will call put_device and it will cause ref_count to decrease extra. that will have that pci device get deleted early wrongly. Need to make get/put balance for both cases.

2012-09-24tile: gxio iorpc numbering change for TRIO interfaceChris Metcalf
An ABI numbering change was made in the hypervisor for Tilera's 4.1 MDE release (just shipped). It's incompatible with the previous 4.0 release ABI numbering, so we track the new numbering going forward. We plan to avoid modifying ABI numbering for these interfaces again.

2012-09-24usb: host: xhci: Fix Null pointer dereferencing with 71c731a for non-x86 systemsVivek Gautam
In 71c731a: usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware when extracting DMI strings (vendor or product_name) to mark them as quirk we may get NULL pointer in case of non-x86 systems which won't define CONFIG_DMI. Hence susbsequent strstr() calls crash while driver probing. So, returning 'false' here in case we get a NULL vendor or product_name. This is tested with ARM (exynos) system. This patch should be backported to stable kernels as old as 3.6, that contain the commit 71c731a296f1b08a3724bd1b514b64f1bda87a23 "usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware" Signed-off-by: Vivek Gautam <gautam.vivek@samsung.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Reported-by: Sebastian Gottschall (DD-WRT) <s.gottschall@dd-wrt.com> Cc: stable@vger.kernel.org
2012-09-24Increase XHCI suspend timeout to 16msMichael Spang
The Intel XHCI specification says that after clearing the run/stop bit the controller may take up to 16ms to halt. We've seen a device take 14ms, which with the current timeout of 10ms causes the kernel to abort the suspend. Increasing the timeout to the recommended value fixes the problem. This patch should be backported to kernels as old as 2.6.37, that contain the commit 5535b1d5f8885695c6ded783c692e3c0d0eda8ca "USB: xHCI: PCI power management implementation".

Currently scan operation is delayed/aborted based on Tx traffic consistency. This decision is taken after receiving scan response of first scan command from FW. But when heavy traffic is running, we can not even afford to send first scan command and go off channel for 30msec. We will block scan request in this case.
