2012-04-19xen/xenbus: Add quirk to deal with misconfigured backends.Konrad Rzeszutek Wilk1-16/+53
A rather annoying and common case is when booting a PVonHVM guest and exposing the PV KBD and PV VFB - as broken toolstacks don't always initialize the backends correctly. Normally The HVM guest is using the VGA driver and the emulated keyboard for this (though upstream version of QEMU implements PV KBD, but still uses a VGA driver). We provide a very basic two-stage wait mechanism - where we wait for 30 seconds for all devices, and then for 270 for all them except the two mentioned. That allows us to wait for the essential devices, like network or disk for the full 6 minutes. To trigger this, put this in your guest config: vfb = [ 'vnc=1, vnclisten=0.0.0.0 ,vncunused=1'] instead of this: vnc=1 vnclisten="0.0.0.0" CC: [email protected] Acked-by: Stefano Stabellini <[email protected]> [v3: Split delay in non-essential (30 seconds) and essential devices per Ian and Stefano suggestion] [v4: Added comments per Stefano suggestion] Signed-off-by: Konrad Rzeszutek Wilk <[email protected]>

When the force changes went in back in 3.3.0, we ended up returning disconnected in the !force case, and the connected in when forced, as it hit the hardcoded check. Fix it so all exits go via the hardcoded check and stop spurious modesets on platforms with hardcoded EDIDs.

2012-04-19drm: Releasing FBs before releasing GEM objects during drm_releasePrathyush1-3/+3
During DRM release, all the FBs and gem objects are released. If a gem object is being used as a FB and set to a crtc, it must not be freed before releasing the framebuffer first. If FBs are released first, the crtc using the FB is disabled first so now the GEM object can be freed safely. The CRTC will be enabled again when the driver restores fbdev mode.

2012-04-18pch_uart: Fix dma channel unallocated issueTomoya MORINAGA1-1/+3
This driver anticipates pch_uart_verify_port() is not called during installation. However, actually pch_uart_verify_port() is called during installation. As a result, memory access violation occurs like below. 0. initial value: use_dma=0 1. starup() - dma channel is not allocated because use_dma=0 2. pch_uart_verify_port() - Set use_dma=1 3. UART processing acts DMA mode because use_dma=1 - memory access violation occurs! This patch fixes the issue. Solution: Whenever pch_uart_verify_port() is called and then dma channel is not allocated, the channel should be allocated.

They can generate interrupts whenever the STS_FLR status bit is turned on, even though that bit is masked out in the Interrupt Enable register.

2012-04-18hwmon: fam15h_power: fix bogus values with current BIOSesAndre Przywara1-0/+39
Newer BKDG[1] versions recommend a different initialization value for the running average range register in the northbridge. This improves the power reading by avoiding counter saturations resulting in bogus values for anything below about 80% of TDP power consumption. Updated BIOSes will have this new value set up from the beginning, but meanwhile we correct this value ourselves. This needs to be done on all northbridges, even on those where the driver itself does not register at. This fixes the driver on all current machines to provide proper values for idle load.

2012-04-18Revert "ACPI: Make ACPI interrupt threaded"Thomas Gleixner1-2/+1
This reverts commit 6fe0d0628245fdcd6fad8b837c81e8f7ebc3364d. Paul bisected this regression. The conversion was done blindly and is wrong, as it does not provide a primary handler to disable the level type irq on the device level. Neither does it set the IRQF_ONESHOT flag which handles that at the irq line level. This can't be done as the interrupt might be shared, though we might extend the core to force it. So an interrupt on this line will wake up the thread, but immediately unmask the irq after that. Due to the interrupt being level type the hardware interrupt is raised over and over and prevents the irq thread from handling it. Fail. request_irq() unfortunately does not refuse such a request and the patch was obviously never tested with real interrupts.

2012-04-18[media] dvb_frontend: Fix a regression when switching back to DVB-SMauro Carvalho Chehab1-1/+24
There are some softwares (Kaffeine and likely xine) that uses a DVBv5 call to switch to DVB-S2, but expects that a DVBv3 call to switch back to DVB-S. Well, this is not right, as a DVBv3 call doesn't know anything about delivery systems. However, as, by accident, this used to work, we need to restore its behavior, in order to avoid regressions with those softwares.

2012-04-17davinci_mdio: Fix MDIO timeout checkChristian Riesch1-0/+5
Under heavy load (flood ping) it is possible for the MDIO timeout to expire before the loop checks the GO bit again. This patch adds an additional check whether the operation was done before actually returning -ETIMEDOUT. To reproduce this bug, flood ping the device, e.g., ping -f -l 1000 After some time, a "timed out waiting for user access" warning may appear. And even worse, link may go down since the PHY reported a timeout.

2012-04-17EHCI: fix criterion for resuming the root hubAlan Stern1-1/+1
This patch (as1542) changes the criterion ehci-hcd uses to tell when it needs to resume the controller's root hub. A resume is needed when a port status change is detected, obviously, but only if the root hub is currently suspended. Right now the driver tests whether the root hub is running, and that is not the correct test. In particular, if the controller has died then the root hub should not be restarted. In addition, some buggy hardware occasionally requires the root hub to be running and sending out SOF packets even while it is nominally supposed to be suspended. In the end, the test needs to be changed. Rather than checking whether the root hub is currently running, the driver will now check whether the root hub is currently suspended. This will yield the correct behavior in all cases.
