| * usbnet: Remove over-broad module alias from zaurus.Dave Jones2011-06-291-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | This module and a bunch of dependancies are getting loaded on several of laptops I have (probably picking up the mobile broadband device), that have nothing to do with zaurus. Matching by class without any vendor/device pair isn't the right thing to do here, as it will prevent any other driver from correctly binding to it. (Or in the absense of a driver, will just waste time & memory by unnecessarily loading modules) Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Prior to this patch, we would always actively drive the GPIO output to either 0 or 1, this patch drove the GPIO active to 0, and put the GPIO in tristate to drive it to 1, unfortunately this does not work, revert back to active driving. Using a signed variable (gstate) to hold the gpio state and using a bit- wise operation on it also resulted in toggling value from 1 to -2 since the variable is signed. This value was then passed on to gpio_direction_ output, which always perform a if (value) ... to set the value to the gpio, so we were always writing a 1 to this GPIO instead of 1 -> 0 -> 1 ...

So don't use KERN_ERR that ends up spamming the console even in quiet mode, it's not _that_ critical. Explained by Jeff: "Long explanation, it's a mess: Marvell took standard AHCI, and bastardized it to include a weird mode whereby PATA devices appear inside the AHCI DMA and interrupt infrastructure you're familiar with. So, PATA devices appear via pata_marvell driver, using basic legacy IDE programming interface. But SATA devices, which might also be attached to this chip, either work in under-performing mode or simply don't work at all (e.g. newer 6 Gbps devices or port multiplier attachments, NCQ, ...) On the other hand, 'ahci' driver loads and works with the chip's attached SATA devices quite beautifully, but is completely unable to drive any attached PATA devices, due to the Marvell-specific PATA-under-AHCI interface. The "masking port_map 0x7 -> 0x3" message is the ahci driver "hiding" the PATA port(s) from itself, making sure it will only drive the SATA ports it knows how to drive."

Userspace gets forcewake lock, lock count >=1 2. GPU hang/reset occurs (forcewake bit is reset) 3. count is now incorrect The failure can only occur when using the forcewake userspace lock. This has the unfortunate consequence of messing up the driver as well as userspace, unless userspace closes the debugfs file, the kernel will never end up waking the GT since the refcount will be > 1. The solution is to try to recover the correct forcewake state based on the refcount. There is a period of time where userspace reads/writes may occur after the reset, before the GT has been forcewaked. The interface was never designed to be a perfect solution for userspace reads/writes, and the kernel portion is fixed by this patch.

Most HC implementations have selected to treat these registers as part of a 32-bit register, giving the same layout for both big and small endian systems. This patch adds a new quirk, big_endian_capbase, to support controllers with big endian register interfaces that treat HCIVERSION and CAPLENGTH as individual registers. Signed-off-by: Jan Andersson <jan@gaisler.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> The reading of the HC capability register has been moved by that commit to a place where the ehci->caps field is not initialized yet. This patch moves the reading of the register back to the original place.
