2010-07-26[CPUFREQ] Fix PCC driver error pathMatthew Garrett1-8/+9
The PCC cpufreq driver unmaps the mailbox address range if any CPUs fail to initialise, but doesn't do anything to remove the registered CPUs from the cpufreq core resulting in failures further down the line. We're better off simply returning a failure - the cpufreq core will unregister us cleanly if we end up with no successfully registered CPUs. Tidy up the failure path and also add a sanity check to ensure that the firmware gives us a realistic frequency - the core deals badly with that being set to 0.

2010-07-26[CPUFREQ] pcc driver should check for pcch method before calling _OSCMatthew Garrett1-1/+5
The pcc specification documents an _OSC method that's incompatible with the one defined as part of the ACPI spec. This shouldn't be a problem as both are supposed to be guarded with a UUID. Unfortunately approximately nobody (including HP, who wrote this spec) properly check the UUID on entry to the _OSC call. Right now this could result in surprising behaviour if the pcc driver performs an _OSC call on a machine that doesn't implement the pcc specification. Check whether the PCCH method exists first in order to reduce this probability.

2010-07-26sysfs: Don't allow the creation of symlinks we can't removeEric W. Biederman1-5/+18
Recently my tagged sysfs support revealed a flaw in the device core that a few rare drivers are running into such that we don't always put network devices in a class subdirectory named net/. Since we are not creating the class directory the network devices wind up in a non-tagged directory, but the symlinks to the network devices from /sys/class/net are in a tagged directory. All of which works until we go to remove or rename the symlink. When we remove or rename a symlink we look in the namespace of the target of the symlink. Since the target of the symlink is in a non-tagged sysfs directory we don't have a namespace to look in, and we fail to remove the symlink. Detect this problem up front and simply don't create symlinks we won't be able to remove later. This prevents symlink leakage and fails in a much clearer and more understandable way.

2010-07-26USB: usb-storage: fix initializations of urb fieldsBob Copeland1-3/+1
Commit 0ede76fcec5415ef82a423a95120286895822e2d, "USB: remove uses of URB_NO_SETUP_DMA_MAP" introduced a regression by inadvertantly removing initialization of the transfer flags. This caused initialization failures in the ums-karma driver. Fix the regression by zeroing it. While at it, as Alan Stern points out, the initializers for actual_length and status are handled by the core and error_count only matters for isochronous urbs, so they don't need to be set here. Remove them. Signed-off-by: Bob Copeland <[email protected]> Acked-by: Alan Stern <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2010-07-26USB: xhci: Set Mult field in endpoint context correctly.Sarah Sharp1-2/+3
The bmAttributes field of the SuperSpeed Endpoint Companion Descriptor has different meanings, depending on the endpoint type. If the endpoint is isochronous, the bmAttributes field is the maximum number of packets within a service interval that this endpoint supports. If the endpoint is bulk, it's the number of stream IDs this endpoint supports. Only set the Mult field of the xHCI endpoint context using the bmAttributes field if the endpoint is isochronous, and the device is a SuperSpeed device.

When an attempt is made to read the interface strings of the Artisman Watchdog USB dongle (idVendor:idProduct 04b4:0526) an error is written to the dmesg log (uhci_result_common: failed with status 440000) and the dongle resets itself, resulting in a disconnect/reconnect loop. Adding the dongle to the list of devices in quirks.c, with the same quirk Alan Stern's previous patch for the Saitek Cyborg Gold 3D joystick, stops the device from resetting and allows it to be used with no problems.

2010-07-26USB: xhci: Set EP0 dequeue ptr after reset of configured device.Sarah Sharp3-0/+25
When a configured device is reset, the control endpoint's ring is reused. If control transfers to the device were issued before the device is reset, the dequeue pointer will be somewhere in the middle of the ring. If the device is then issued an address with the set address command, the xHCI driver must provide a valid input context for control endpoint zero. The original code would give the hardware the original input context, which had a dequeue pointer set to the top of the ring. This would cause the host to re-execute any control transfers until it reached the ring's enqueue pointer. When issuing a set address command for a device that has just been configured and then reset, use the control endpoint's enqueue pointer as the hardware's dequeue pointer. Assumption: All control transfers will be completed or cancelled before the set address command is issued to the device. If there are any outstanding control transfers, this code will not work.

2010-07-26USB: Fix USB3.0 Port Speed Downgrade after port resetSarah Sharp1-0/+2
Without this fix, a USB 3.0 port is downgraded to full speed after a port reset of a configured device. The USB 3.0 terminations will be disabled permanently, and USB 3.0 devices will always enumerate as full speed devices, until the host controller is unplugged (if it is an ExpressCard) or the computer is rebooted. Fajun Chen traced this traced the speed downgrade issue to the port reset and the interpretation of port status in USB hub driver code. The hub code was not testing for the port being a SuperSpeed port, and it fell through to the else case of Full Speed. The following patch adds SuperSpeed mapping from the port status, and fixes the speed downgrade issue.

2010-07-26USB: xHCI: Fix another bug in link TRB activation change.Sarah Sharp1-4/+7
Commit 6c12db90f19727c76990e7f4801c67a148b30111 also seems to have introduced a bug that is triggered when the command ring is about to wrap. The inc_enq() function will not have moved the enqueue pointer past the link TRB. It is supposed to be moved past the link TRB in prepare_ring(), which should be called before a TD is enqueued. However, the queue_command() function never calls the prepare_ring() function because prepare_ring() is only supposed to be used for endpoint rings. That means the enqueue pointer will not be moved past the link TRB, and will get overwritten. The fix is to make queue_command() call prepare_ring() with a fake endpoint status (set to running). Then the enqueue pointer will get moved past the link TRB. Signed-off-by: Sarah Sharp <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

BugLink: https://bugs.launchpad.net/bugs/597075 commit f1befe71fa7a79ab733011b045639d8d809924ad introduced a regression when detecting aperture size of some i915 adapters, e.g., those on the Intel Q35 chipset.

This fixes a potential modesetting error during boot with plymouth on Broadwater and Crestline introduced with 9df47c. The framebuffer was hard-coding an alignment of 64K, but the modesetting code required the documented alignment of 128K. The result was that we would attempt to unbind the pinned fbcon buffer, triggering an ERROR and ultimately failing the mode change.

2010-07-26drm/i915: make sure eDP panel is turned onJesse Barnes1-2/+51
When enabling the eDP port, we need to make sure the panel is turned on after training the link. If we don't, it likely won't come back after suspend or may not come up at all. For unknown reasons, unlocking the panel regs before initiating a power on sequence is necessary. There are known bugs in the PCH panel sequencing logic, apparently this is one possible workaround.

In some cases, unlocking the panel regs is safe and can help us avoid a flickery, full mode set sequence. So define the unlock key and use it. Signed-off-by: Jesse Barnes <[email protected]> Signed-off-by: Eric Anholt <[email protected]>
2010-07-26drm/i915: Make G4X-style PLL search more permissiveAdam Jackson1-2/+2
Fixes an Ironlake laptop with a 68.940MHz 1280x800 panel and 120MHz SSC reference clock. More generally, the 0.488% tolerance used before is just too tight to reliably find a PLL setting. I extracted the search algorithm and modified it to find the dot clocks with maximum error over the valid range for the given output type: http://people.freedesktop.org/~ajax/intel_g4x_find_best_pll.c This gave: Worst dotclock for Ironlake DAC refclk is 350000kHz (error 0.00571) Worst dotclock for Ironlake SL-LVDS refclk is 102321kHz (error 0.00524) Worst dotclock for Ironlake DL-LVDS refclk is 219642kHz (error 0.00488) Worst dotclock for Ironlake SL-LVDS SSC refclk is 84374kHz (error 0.00529) Worst dotclock for Ironlake DL-LVDS SSC refclk is 183035kHz (error 0.00488) Worst dotclock for G4X SDVO refclk is 267600kHz (error 0.00448) Worst dotclock for G4X HDMI refclk is 334400kHz (error 0.00478) Worst dotclock for G4X SL-LVDS refclk is 95571kHz (error 0.00449) Worst dotclock for G4X DL-LVDS refclk is 224000kHz (error 0.00510) Signed-off-by: Adam Jackson <[email protected]> Cc: [email protected] Signed-off-by: Eric Anholt <[email protected]>
2010-07-26MIPS: Set io_map_base for several PCI bridges lacking itBen Hutchings5-1/+6
Several MIPS platforms don't set pci_controller::io_map_base for their PCI bridges. This results in a panic in pci_iomap(). (The panic is conditional on CONFIG_PCI_DOMAINS, but that is now enabled for all PCI MIPS systems.)

2010-07-26MIPS: Alchemy: Define eth platform devices in the correct orderWolfgang Grandegger1-4/+5
Currently, the eth devices are probed in the inverse order, first au1xxx_eth1_device and then au1xxx_eth0_device. On the GPR board, this makes trouble: # ifconfig|grep HWaddr eth0 Link encap:Ethernet HWaddr 00:50:C2:0C:30:01 eth1 Link encap:Ethernet HWaddr 66:22:01:80:38:10 A bogous ethernet hwaddr is assigned to the first device and au1xxx_eth0_device is mapped to eth1, which even does not work properly. With this patch, the problems are gone: # ifconfig|grep HWaddr eth0 Link encap:Ethernet HWaddr 66:22:11:32:38:10 eth1 Link encap:Ethernet HWaddr 66:22:11:32:38:11 Signed-off-by: Wolfgang Grandegger <[email protected]> To: [email protected] Patchwork: https://patchwork.linux-mips.org/patch/1473/ Signed-off-by: Ralf Baechle <[email protected]>

2010-07-26MIPS: MTX-1: Fix PCI on the MeshCube and related boardsBruno Randolf1-5/+3
This patch fixes a regression introduced by commit "MIPS: Alchemy: MTX-1: Use linux gpio api." (bb706b28bbd647c2fd7f22d6bf03a18b9552be05) which broke PCI bus operation. The problem is caused by alchemy_gpio2_enable() which resets the GPIO2 block. Two PCI signals (PCI_SERR and PCI_RST) are connected to GPIO2 and they obviously do not to like the reset. Since GPIO2 is correctly initialized by the boot monitor (YAMON) it is not necessary to call this function, so just remove it. Also replace gpio_set_value() with alchemy_gpio_set_value() to avoid problems in case gpiolib gets initialized after PCI. And since alchemy gpio_set_value() calls au_sync() we don't have to au_sync() again later.
