2010-06-22hso: remove setting of low_latency flagFilip Aben1-1/+0
This patch removes the setting of the low_latency flag. tty_flip_buffer_push() is occasionally being called in irq context, which causes a hang if the low_latency flag is set. Removing the low_latency flag only seems to impact the flush to ldisc, which will now be put on a workqueue. Signed-off-by: Filip Aben <[email protected]> Signed-off-by: David S.

2010-06-20hwmon: (k8temp) Bypass core swapping on single-core processorsJean Delvare1-1/+1
Commit a2e066bba2aad6583e3ff648bf28339d6c9f0898 introduced core swapping for CPU models 64 and later. I recently had a report about a Sempron 3200+, model 95, for which this patch broke temperature reading. It happens that this is a single-core processor, so the effect of the swapping was to read a temperature value for a core that didn't exist, leading to an incorrect value (-49 degrees C.) Disabling core swapping on singe-core processors should fix this. Additional comment from Andreas: The BKDG says Thermal Sensor Core Select (ThermSenseCoreSel)-Bit 2. This bit selects the CPU whose temperature is reported in the CurTemp field. This bit only applies to dual core processors. For single core processors CPU0 Thermal Sensor is always selected. k8temp_probe() correctly detected that SEL_CORE can't be used on single core CPU. Thus k8temp did never update the temperature values stored in temp[1][x] and -49 degrees was reported. For single core CPUs we must use the values read into temp[0][x].

2010-06-18drm/i915: gen3 page flipping fixesJesse Barnes6-9/+46
Gen3 chips have slightly different flip commands, and also contain a bit that indicates whether a "flip pending" interrupt means the flip has been queued or has been completed. So implement support for the gen3 flip command, and make sure we use the flip pending interrupt correctly depending on the value of ECOSKPD bit 0.

2010-06-18drm/i915: don't queue flips during a flip pending eventJesse Barnes1-0/+11
Hardware will set the flip pending ISR bit as soon as it receives the flip instruction, and (supposedly) clear it once the flip completes (e.g. at the next vblank). If we try to send down a flip instruction while the ISR bit is set, the hardware can become very confused, and we may never receive the corresponding flip pending interrupt, effectively hanging the chip.

2010-06-18PCI/PM: Do not use native PCIe PME by defaultRafael J. Wysocki1-6/+13
Commit c7f486567c1d0acd2e4166c47069835b9f75e77b (PCI PM: PCIe PME root port service driver) causes the native PCIe PME signaling to be used by default, if the BIOS allows the kernel to control the standard configuration registers of PCIe root ports. However, the native PCIe PME is coupled to the native PCIe hotplug and calling pcie_pme_acpi_setup() makes some BIOSes expect that the native PCIe hotplug will be used as well. That, in turn, causes problems to appear on systems where the PCIe hotplug driver is not loaded. The usual symptom, as reported by Jaroslav Kameník and others, is that the ACPI GPE associated with PCIe hotplug keeps firing continuously causing kacpid to take substantial percentage of CPU time. To work around this issue, change the default so that the native PCIe PME signaling is only used if directly requested with the help of the pcie_pme= command line switch. Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15924 , which is a listed regression from 2.6.33. Signed-off-by: Rafael J.

2010-06-17ACPI / PM: Do not enable GPEs for system wakeup in advanceRafael J. Wysocki2-15/+9
After commit 9630bdd9b15d2f489c646d8bc04b60e53eb5ec78 (ACPI: Use GPE reference counting to support shared GPEs) the wakeup enable mask bits of GPEs are set as soon as the GPEs are enabled to wake up the system. Unfortunately, this leads to a regression reported by Michal Hocko, where a system is woken up from ACPI S5 by a device that is not supposed to do that, because the wakeup enable mask bit of this device's GPE is always set when acpi_enter_sleep_state() calls acpi_hw_enable_all_wakeup_gpes(), although it should only be set if the device is supposed to wake up the system from the target state. To work around this issue, rework the ACPI power management code so that GPEs are not enabled to wake up the system upfront, but only during a system state transition when the target state of the system is known. [Of course, this means that the reference counting of "wakeup" GPEs doesn't really make sense and it is sufficient to set/unset the wakeup mask bits for them during system sleep transitions. This will allow us to simplify the GPE handling code quite a bit, but that change is too intrusive for 2.6.35.] Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15951 Signed-off-by: Rafael J.

2010-06-17bnx2: fix dma_get_ops compilation breakageFUJITA Tomonori1-7/+4
This removes dma_get_ops() prefetch optimization in bnx2. bnx2 uses dma_get_ops() to see if dma_sync_single_for_cpu() is noop. bnx2 does prefetch if it's noop. But dma_get_ops() isn't available on all the architectures (only the architectures that uses dma_map_ops struct have it). Using dma_get_ops() in drivers leads to compilation breakage on many architectures. This patch removes dma_get_ops() and changes bnx2 to do prefetch on all the architectures. This adds useless prefetch on non-coherent architectures but this is harmless. It is also unlikely to cause the performance drop.

This situation confuses the driver, and so the skb_put() sanity check fails. This patch fixes the issue by adding an appropriate check, i.e. the driver should not try to process frames with buffer descriptor's length over rx_buffer_size (i.e. maxfrm and mrblr). Note that sometimes eTSEC works correctly, i.e. in the second (last) buffer descriptor bits 'truncated' and 'crcerr' are set, and so there's no oops.

2010-06-16gianfar: Fix setup of RX time stampingManfred Rudigier1-4/+17
Previously the RCTRL_TS_ENABLE bit was set unconditionally. However, if the RCTRL_TS_ENABLE is set without TMR_CTRL[TE], the driver does not work properly on some boards (Anton had problems with the MPC8313ERDB and MPC8568EMDS). With this patch the bit will only be set if requested from user space with the SIOCSHWTSTAMP ioctl command, meaning that time stamping is disabled during normal operation. Users who are not interested in time stamps will not experience problems with buggy CPU revisions or performance drops any more. The setting of TMR_CTRL[TE] is still up to the user. This is considered safe because users wanting HW timestamps must initialize the eTSEC clock first anyway, e.g. with the recently submitted PTP clock driver.

Certain revisions of this chipset appear to be broken. There is a shadow GTT which mirrors the real GTT but contains pre-translated physical addresses, for performance reasons. When a GTT update happens, the translations are done once and the resulting physical addresses written back to the shadow GTT. Except sometimes, the physical address is actually written back to the _real_ GTT, not the shadow GTT. Thus we start to see faults when that physical address is fed through translation again.

2010-06-15OMAPFB: LCDC: change update_mode to DISABLED when going suspendJanusz Krzysztofik1-12/+2
I was observing the following error messages on my OMAP1 based Amstrad Delta board when first changing from text to graphics mode or vice versa after the LCD display had been blanked: omapfb omapfb: timeout waiting for FRAME DONE with a followup error message while unblanking it back: omapfb omapfb: resetting (status 0xffffffb2,reset count 1) As a visible result, image pixels happened to be shifted by a few bits, giving wrong colors. Examining the code, I found that this problem occures when an OMAP1 internal LCD controller is disabled from omap_lcdc_suspend() and then a subsequent omap_lcdc_setup_plane() calls disable_controller() again. This potentially error provoking behaviour is triggered by the lcdc.update_mode flag being kept at OMAP_AUTO_UPDATE, regardless of the controller and panel being suspended. This patch tries to correct the problem by replacing both omap_lcdc_suspend() and omap_lcdc_resume() function bodies with single calls to omap_lcdc_set_update_mode() with a respective OMAP_UPDATE_DISABLE or OMAP_AUTO_UPDATE argument. As a result, exactly the same lower level operations are performed, with addition of changing the lcdc.update_mode flag to a value better suited for the controller state. This prevents any further calls to disable_controller() from omap_lcdc_setup_plane() while the display is suspended. Created against linux-2.6.34-rc7. Tested on Amstrad Delta.

Installing 2.6.34 on a Power5/rn50 combo machine, X showed buggy sw rendering, enabling tiling in the DDX fixed it.

2010-06-14iwlagn: verify flow id in compressed BA packetShanyu Zhao1-0/+5
The flow id (scd_flow) in a compressed BA packet should match the txq_id of the queue from which the aggregated packets were sent. However, in some hardware like the 1000 series, sometimes the flow id is 0 for the txq_id (10 to 19). This can cause the annoying message: [ 2213.306191] iwlagn 0000:01:00.0: Received BA when not expected [ 2213.310178] iwlagn 0000:01:00.0: Read index for DMA queue txq id (0), index 5, is out of range [0-256] 7 7. And even worse, if agg->wait_for_ba is true when the bad BA is arriving, this can cause system hang due to NULL pointer dereference because the code is operating in a wrong tx queue!

This was a very hard to trigger race condition. If we got a state packet from the peer, after drbd_nl_disk() has already changed the disk state to D_NEGOTIATING but after_state_ch() was not yet run by the worker, then receive_state() might called drbd_sync_handshake(), which in turn crashed when accessing p_uuid.
