2011-03-21PCI: Changing ASPM policy, via /sys, to POWERSAVE could cause NMIsNaga Chumbalkar
v3 -> v2: Modified the text that describes the problem v2 -> v1: Returned -EPERM v1 : http://marc.info/?l=linux-pci&m=130013194803727&w=2 For servers whose hardware cannot handle ASPM the BIOS ought to set the FADT bit shown below: In Sec 5.2.9.3 (IA-PC Boot Arch. Flags) of ACPI4.0a Specification, please see Table 5-11: PCIe ASPM Controls: If set, indicates to OSPM that it must not enable OPSM ASPM control on this platform. However there are shipping servers whose BIOS did not set this bit. (An example is the HP ProLiant DL385 G6. A Maintenance BIOS will fix that). For such servers even if a call is made via pci_no_aspm(), based on _OSC support in the BIOS, it may be too late because the ASPM code may have already allocated and filled its "link_list". So if a user sets the ASPM "policy" to "powersave" via /sys then pcie_aspm_set_policy() will run through the "link_list" and re-configure ASPM policy on devices that advertise ASPM L0s/L1 capability: # echo powersave > /sys/module/pcie_aspm/parameters/policy # cat /sys/module/pcie_aspm/parameters/policy default performance [powersave] That can cause NMIs since the hardware doesn't play well with ASPM: [ 1651.906015] NMI: PCI system error (SERR) for reason b1 on CPU 0. [ 1651.906015] Dazed and confused, but trying to continue Ideally, the BIOS should have set that FADT bit in the first place but we could be more robust - especially given the fact that Windows doesn't cause NMIs in the above scenario. There should be a sanity check to not allow a user to modify ASPM policy when aspm_disabled is set. Signed-off-by: Naga Chumbalkar <nagananda.chumbalkar@hp.com> Acked-by: Rafael J.

2011-03-21PCI: PCIe links may not get configured for ASPM under POWERSAVE modeNaga Chumbalkar
v3 -> v2: Moved ASPM enabling logic to pci_set_power_state() v2 -> v1: Preserved the logic in pci_raw_set_power_state() : Added ASPM enabling logic after scanning Root Bridge : http://marc.info/?l=linux-pci&m=130046996216391&w=2 v1 : http://marc.info/?l=linux-pci&m=130013164703283&w=2 The assumption made in commit 41cd766b065970ff6f6c89dd1cf55fa706c84a3d (PCI: Don't enable aspm before drivers have had a chance to veto it) that pci_enable_device() will result in re-configuring ASPM when aspm_policy is POWERSAVE is no longer valid. This is due to commit 97c145f7c87453cec90e91238fba5fe2c1561b32 (PCI: read current power state at enable time) which resets dev->current_state to D0. Due to this the call to pcie_aspm_pm_state_change() is never made. Note the equality check (below) that returns early: ./drivers/pci/pci.c: pci_raw_set_pci_power_state() 546 /* Check if we're already there */ 547 if (dev->current_state == state) 548 return 0; Therefore OSPM never configures the PCIe links for ASPM to turn them "on". Fix it by configuring ASPM from the pci_enable_device() code path. This also allows a driver such as the e1000e networking driver a chance to disable ASPM (L0s, L1), if need be, prior to enabling the device. A driver may perform this action if the device is known to mis-behave wrt ASPM. Signed-off-by: Naga Chumbalkar <nagananda.chumbalkar@hp.com> Acked-by: Rafael J.

2011-03-21PCI/ACPI: Report ASPM support to BIOS if not disabled from command lineRafael J. Wysocki
We need to distinguish the situation in which ASPM support is disabled from the command line or through .config from the situation in which it is disabled, because the hardware or BIOS can't handle it. In the former case we should not report ASPM support to the BIOS through ACPI _OSC, but in the latter case we should do that. Introduce pcie_aspm_support_enabled() that can be used by acpi_pci_root_add() to determine whether or not it should report ASPM support to the BIOS through _OSC.

2011-03-21HID: add support for Skycable 0x3f07 wireless presenterJiri Kosina
This device contains the very same bug in report descriptor as the Ortek ones do (i.e. LogicalMinimum == 1, which is wrong for the key array). As we have more reports for the Ortek devices, we are keeping the driver name for now. Apparently there is a chip producer which sells chip with this buggy descriptor to multiple vendors. Thus if such reports start to come at highger frequency, we'll either have to rename the driver accordingly, or come up with more generic workaround. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Below is a patch against drm-next branch of 2.6.38-rc8+ kernel that adds the capability to wait on vblank events for CRTCs that are greater than 1 and thus cannot be represented with primary/secondary flags in the legacy interface. It was discussed on the dri-devel list in these two threads: http://lists.freedesktop.org/archives/dri-devel/2011-March/009009.html http://lists.freedesktop.org/archives/dri-devel/2011-March/009025.html This patch extends the interface to drm_wait_vblank ioctl so that crtc>1 can be represented. It also adds a new capability to drm_getcap ioctl so that the user space can check whether the new interface to drm_wait_vblank is supported (and fall back to the legacy interface if not) Signed-off-by: Ilija Hadzic <ihadzic@research.bell-labs.com> Reviewed-by: Mario Kleiner <mario.kleiner at tuebingen.mpg.de> Acked-by: Mario Kleiner <mario.kleiner at tuebingen.mpg.de> Reviewed-by: Alex Deucher <alexdeucher@gmail.com> Tested-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2011-03-20firewire: core: ignore link-active bit of new nodes, fix device recognitionStefan Richter
Like the older ieee1394 core driver, firewire-core skipped scanning of any new node whose PHY sent a self ID without "link active" bit. If a device had this bit off mistakenly, it meant that it was inaccessible to kernel drivers with the old IEEE 1394 driver stack but could still be accessed by userspace drivers through the raw1394 interface. But with firewire-core, userspace drivers don't get to see such buggy devices anymore. This is effectively a driver regression since this device bug is otherwise harmless. We now attempt to scan all devices, even repeaters that don't have a link or powered-down devices that have everything but their PHY shut down when plugged in. This results in futile repeated scanning attempts in case of such devices that really don't have an active link, but this doesn't hurt since recent workqueue infrastructure lets us run more concurrent scanning jobs than we can shake a stick at. This should fix accessibility of Focusrite Saffire PRO 26 I/O: http://sourceforge.net/mailarchive/forum.php?thread_name=20110314215622.5c751bb0%40stein&forum_name=ffado-user Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2011-03-20firewire: core: increase default SPLIT_TIMEOUT valueClemens Ladisch
The SPLIT_TIMEOUT mechanism is intended to detect requests that somehow got lost. However, when the timeout value is too low, transactions that could have been completed successfully will be cancelled. Furthermore, there are chips whose firmwares ignore the configured split timeout and send late split response; known examples are the DM1x00 (BeBoB), TCD22x0 (DICE), and some OXUF936QSE firmwares. This patch changes the default timeout to two seconds, which happens to be the default on other OSes, too. Actual lost requests are extremely rare, so there should be no practical downside to increasing the split timeout even on devices that work correctly.

2011-03-19niu: Rename NIU parent platform device name to fix conflict.David S. Miller
When the OF device driver bits were converted over to the platform device infrastructure in commit 74888760d40b3ac9054f9c5fa07b566c0676ba2d ("dt/net: Eliminate users of of_platform_{,un}register_driver") we inadvertantly created probing problems in the OF case. The NIU driver creates a dummy platform device to represent the board that contains one or more child NIU devices. Unfortunately we use the same name, "niu", as the OF device driver itself uses. The result is that we try to probe the dummy "niu" parent device we create, and since it has a NULL ofdevice pointer etc. everything explodes: [783019.128243] niu: niu.c:v1.1 (Apr 22, 2010) [783019.128810] Unable to handle kernel NULL pointer dereference [783019.128949] tsk->{mm,active_mm}->context = 000000000000039e [783019.129078] tsk->{mm,active_mm}->pgd = fffff803afc5a000 [783019.129206] \|/ ____ \|/ [783019.129213] "@'/ .. \`@" [783019.129220] /_| \__/ |_\ [783019.129226] \__U_/ [783019.129378] modprobe(2004): Oops [#1] [783019.129423] TSTATE: 0000000011001602 TPC: 0000000010052ff8 TNPC: 000000000061bbb4 Y: 00000000 Not tainted [783019.129542] TPC: <niu_of_probe+0x3c/0x2dc [niu]> [783019.129624] g0: 8080000000000000 g1: 0000000000000000 g2: 0000000010056000 g3: 0000000000000002 [783019.129733] g4: fffff803fc1da0c0 g5: fffff800441e2000 g6: fffff803fba84000 g7: 0000000000000000 [783019.129842] o0: fffff803fe7df010 o1: 0000000010055700 o2: 0000000000000000 o3: fffff803fbacaca0 [783019.129951] o4: 0000000000000080 o5: 0000000000777908 sp: fffff803fba866e1 ret_pc: 0000000010052ff4 [783019.130083] RPC: <niu_of_probe+0x38/0x2dc [niu]> [783019.130165] l0: fffff803fe7df010 l1: fffff803fbacafc0 l2: fffff803fbacaca0 l3: ffffffffffffffed [783019.130273] l4: 0000000000000000 l5: 000000007fffffff l6: fffff803fba86f40 l7: 0000000000000001 [783019.130382] i0: fffff803fe7df000 i1: fffff803fc20aba0 i2: 0000000000000000 i3: 0000000000000001 [783019.130490] i4: 0000000000000000 i5: 0000000000000000 i6: fffff803fba867a1 i7: 000000000062038c [783019.130614] I7: <platform_drv_probe+0xc/0x20> Fix by simply renaming the parent device to "niu-board".

2011-03-18ftmac100: use resource_size()Dan Carpenter
The calculation is off-by-one. It should be "end - start + 1". This patch fixes it to use resource_size() instead. Oddly, the code already uses resource size correctly a couple lines earlier when it calls request_mem_region() for this memory.

2011-03-18ACPI: Use syscore_ops instead of sysdev class and sysdevRafael J. Wysocki
ACPI uses a sysdev class and a sysdev for executing irqrouter_resume() before turning on interrupts on the boot CPU. However, since irqrouter_resume() ignores its argument, the entire mechanism may be replaced with a struct syscore_ops object which is considerably simpler. Signed-off-by: Rafael J.

As specified by errata eTSEC49 of MPC8548 and errata eTSEC12 of MPC83xx, older revisions of gianfar controllers will be unable to calculate a TCP/UDP packet checksum for some alignments of the appropriate FCB. This patch checks for FCB alignment on such controllers and falls back to software checksumming if the alignment is known to be bad.

USB defines usb_device_type pointing to usb_device_pm_ops that provides system-wide PM callbacks only and usb_bus_type pointing to usb_bus_pm_ops that provides runtime PM callbacks only. However, the USB runtime PM callbacks may be defined in usb_device_pm_ops which makes it possible to drop usb_bus_pm_ops and will allow us to consolidate the handling of subsystems by the PM core code.
