2011-06-10treewide: Convert uses of struct resource to resource_size(ptr)Joe Perches
Several fixes as well where the +1 was missing. Done via coccinelle scripts like: @@ struct resource *ptr; @@ - ptr->end - ptr->start + 1 + resource_size(ptr) and some grep and typing. Mostly uncompiled, no cross-compilers. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2011-05-19USB: remove remaining usages of hcd->state from usbcore and fix regressionAlan Stern
This patch (as1467) removes the last usages of hcd->state from usbcore. We no longer check to see if an interrupt handler finds that a controller has died; instead we rely on host controller drivers to make an explicit call to usb_hc_died(). This fixes a regression introduced by commit 9b37596a2e860404503a3f2a6513db60c296bfdc (USB: move usbcore away from hcd->state). It used to be that when a controller shared an IRQ with another device and an interrupt arrived while hcd->state was set to HC_STATE_HALT, the interrupt handler would be skipped. The commit removed that test; as a result the current code doesn't skip calling the handler and ends up believing the controller has died, even though it's only temporarily stopped. The solution is to ignore HC_STATE_HALT following the handler's return. As a consequence of this change, several of the host controller drivers need to be modified. They can no longer implicitly rely on usbcore realizing that a controller has died because of hcd->state. The patch adds calls to usb_hc_died() in the appropriate places. The patch also changes a few of the interrupt handlers. They don't expect to be called when hcd->state is equal to HC_STATE_HALT, even if the controller is still alive. Early returns were added to avoid any confusion.

2011-03-14USB 3.0 Hub ChangesJohn Youn
Update the USB core to deal with USB 3.0 hubs. These hubs have a slightly different hub descriptor than USB 2.0 hubs, with a fixed (rather than variable length) size. Change the USB core's hub descriptor to have a union for the last fields that differ. Change the host controller drivers that access those last fields (DeviceRemovable and PortPowerCtrlMask) to use the union. Translate the new version of the hub port status field into the old version that khubd understands. (Note: we need to fix it to translate the roothub's port status once we stop converting it to USB 2.0 hub status internally.) Add new code to handle link state change status. Send out new control messages that are needed for USB 3.0 hubs, like Set Hub Depth. This patch is a modified version of the original patch submitted by John Youn. It's updated to reflect the removal of the "bitmap" #define, and change the hub descriptor accesses of a couple new host controller drivers.

2011-03-14USB: Remove bitmap #define from hcd.hSarah Sharp
Using a #define to redefine a common variable name is a bad thing, especially when the #define is in a header. include/linux/usb/hcd.h redefined bitmap to DeviceRemovable to avoid typing a long field in the hub descriptor. This has unintended side effects for files like drivers/usb/core/devio.c that include that file, since another header included after hcd.h has different variables named bitmap. Remove the bitmap #define and replace instances of it in the host controller code. Cleanup the spaces around function calls and square brackets while we're at it.

2010-08-10USB: convert usb_hcd bitfields into atomic flagsAlan Stern
This patch (as1393) converts several of the single-bit fields in struct usb_hcd to atomic flags. This is for safety's sake; not all CPUs can update bitfield values atomically, and these flags are used in multiple contexts. The flag fields that are set only during registration or removal can remain as they are, since non-atomic accesses at those times will not cause any problems. (Strictly speaking, the authorized_default flag should become atomic as well. I didn't bother with it because it gets changed only via sysfs. It can be done later, if anyone wants.)

2010-05-20USB: straighten out port feature vs. port status usageAlan Stern
This patch (as1349b) clears up the confusion in many USB host controller drivers between port features and port statuses. In mosty cases it's true that the status bit is in the position given by the corresponding feature value, but that's not always true and it's not guaranteed in the USB spec. There's no functional change, just replacing expressions of the form (1 << USB_PORT_FEAT_x) with USB_PORT_STAT_x, which has the same value.

2010-05-20USB: remove bogus USB_PORT_FEAT_*_SPEED symbolsAlan Stern
This patch (as1348) removes the bogus USB_PORT_FEAT_{HIGHSPEED,SUPERSPEED} symbols from ch11.h. No such features are defined by the USB spec. (There is a PORT_LOWSPEED feature, but the spec doesn't mention it except to say that host software should never use it.) The speed indicators are port statuses, not port features. As a temporary workaround for the xhci-hcd driver, a fictional USB_PORT_STAT_SUPER_SPEED symbol is added.

2010-05-20USB: make hcd.h public (drivers dependency)Eric Lescouet
The usbcore headers: hcd.h and hub.h are shared between usbcore, HCDs and a couple of other drivers (e.g. USBIP modules). So, it makes sense to move them into a more public location and to cleanup dependency of those modules on kernel internal headers.
