| * | sysfs: move sysfs file poll implementation to sysfs_open_direntTejun Heo2007-10-121-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sysfs file poll implementation is scattered over sysfs and kobject. Event numbering is done in sysfs_dirent but wait itself is done on kobject. This not only unecessarily bloats both kobject and sysfs_dirent but is also buggy - if a sysfs_dirent is removed while there still are pollers, the associaton betwen the kobject and sysfs_dirent breaks and kobject may be freed with the pollers still sleeping on it. This patch moves whole poll implementation into sysfs_open_dirent. Each time a sysfs_open_dirent is created, event number restarts from 1 and pollers sleep on sysfs_open_dirent. As event sequence number is meaningless without any open file and pollers should have open file and thus sysfs_open_dirent, this ephemeral event counting works and is a saner implementation. This patch fixes the dnagling sleepers bug and reduces the sizes of kobject and sysfs_dirent by one pointer.

| * | sysfs: Remove first pass at shadow directory supportEric W. Biederman2007-10-122-28/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While shadow directories appear to be a good idea, the current scheme of controlling their creation and destruction outside of sysfs appears to be a locking and maintenance nightmare in the face of sysfs directories dynamically coming and going. Which can now occur for directories containing network devices when CONFIG_SYSFS_DEPRECATED is not set. This patch removes everything from the initial shadow directory support that allowed the shadow directory creation to be controlled at a higher level. So except for a few bits of sysfs_rename_dir everything from commit b592fcfe7f06c15ec11774b5be7ce0de3aa86e73 is now gone. Signed-off-by: Eric W.

| * | kobject: remove the static array for the nameGreg Kroah-Hartman2007-10-121-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to historical reasons, struct kobject contained a static array for the name, and a dynamic pointer in case the name got bigger than the array. That's just dumb, as people didn't always know which variable to reference, even with the accessor for the kobject name. This patch removes the static array, potentially saving a lot of memory as the majority of kobjects do not have a very long name. Thanks to Kay for the idea to do this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as997) fixes a bug in the USB serial core. The core needs to pay attention to drivers' requirements regarding the number and type of endpoints a device has. At the same time, the patch changes the NUM_DONT_CARE constant (which is stored in a single-byte field) from -1 to a safer, unsigned value. It also improves the kerneldoc for several fields in the usb_serial_driver structure. Finally, the patch replaces a list_for_each() with list_for_each_entry().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as995) cleans up the remains of the former NO_AUTOSUSPEND quirk. Since autosuspend is disabled by default, we will let userspace worry about which devices can safely be suspended. Thus the lengthy series of quirk entries is no longer needed, and neither is the quirk ID. I suppose someone might eventually run across a hub that can't be suspended; let's ignore the possibility for now. The patch also cleans up the hasty way in which autosuspend gets disabled. Setting udev->autosuspend_delay to -1 wasn't quite right, because the value is always supposed to be a multiple of HZ. It's better to leave the delay value alone and set autosuspend_disabled, which is what the quirk routine used to do.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as989) makes usbcore flush all outstanding URBs for each device as the device is suspended. This will be true even when CONFIG_USB_SUSPEND is not enabled. In addition, an extra can_submit flag is added to the usb_device structure. That flag will be turned off whenever a suspend request has been received for the device, even if the device isn't actually suspended because CONFIG_USB_SUSPEND isn't set. It's no longer necessary to check for the device state being equal to USB_STATE_SUSPENDED during URB submission; that check can be replaced by a check of the can_submit flag. This also permits us to remove some questionable references to the deprecated power.power_state field.

That can help shrink object code and remove #ifdeffery. - gadget_is_dualspeed(), currently always a compile-time constant (depending on which controller is selected). - gadget_is_otg(), usually a compile time "false", but this is a runtime test if the platform enables OTG (since it's reasonable to populate boards with different USB sockets). It also updates two peripheral controller drivers to use these: - fsl_usb2_udc, mostly OTG-related bugfixes: non-OTG devices must follow the rules about drawing VBUS power, and OTG ones need to reject invalid SET_FEATURE requests. - omap_udc, just scrubbing a bit of #ifdeffery. And also gadgetfs, which lost some #ifdefs and moved to a more standard handling of DEBUG and VERBOSE_DEBUG. The main benefits come from patches which will follow.

| * | USB: cleanup for previous patchesAlan Stern2007-10-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as951) cleans up a few loose ends from earlier patches. Redundant checks for non-NULL urb->dev are removed, as are checks of urb->dev->bus (which can never be NULL). Conversely, a check for non-NULL urb->ep is added to the unlink paths. A homegrown round-down-to-power-of-2 loop is simplified by using the ilog2 routine. The comparison in usb_urb_dir_in() is made more transparent.

| * | USB: avoid using urb->pipe in usbcoreAlan Stern2007-10-121-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as946) eliminates many of the uses of urb->pipe in usbcore. Unfortunately there will have to be a significant API change, affecting all USB drivers, before we can remove it entirely. This patch contents itself with changing only the interface to usb_buffer_map_sg() and friends: The pipe argument is replaced with a direction flag. That can be done easily because those routines get used in only one place. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
| * | USB: add direction bit to urb->transfer_flagsAlan Stern2007-10-121-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as945) adds a bit to urb->transfer_flags for recording the direction of the URB. The bit is set/cleared automatically in usb_submit_urb() so drivers don't have to worry about it (although as a result, it isn't valid until the URB has been submitted). Inline routines are added for easily checking an URB's direction. They replace calls to usb_pipein in the DMA-mapping parts of hcd.c. For non-control endpoints, the direction is determined directly from the endpoint descriptor. However control endpoints are bi-directional; for them the direction is determined from the bRequestType byte and the wLength value in the setup packet.

| * | USB: add ep->enableAlan Stern2007-10-121-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as944) adds an explicit "enabled" field to the usb_host_endpoint structure and uses it in place of the current mechanism. This is merely a time-space tradeoff; it makes checking whether URBs may be submitted to an endpoint simpler. The existing mechanism is efficient when converting urb->pipe to an endpoint pointer, but it's not so efficient when urb->ep is used instead. As a side effect, the procedure for enabling an endpoint is now a little more complicated. The ad-hoc inline code in usb.c and hub.c for enabling ep0 is now replaced with calls to usb_enable_endpoint, which is no longer static.

| * | USB: add urb->epAlan Stern2007-10-121-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as943) prepares the way for eliminating urb->pipe by introducing an endpoint pointer into struct urb. For now urb->ep is set by usb_submit_urb() from the pipe value; eventually drivers will set it themselves and we will remove urb->pipe completely. The patch also adds new inline routines to retrieve an endpoint descriptor's number and transfer type, essentially as replacements for usb_pipeendpoint and usb_pipetype. usb_submit_urb(), usb_hcd_submit_urb(), and usb_hcd_unlink_urb() are converted to use the new field and new routines. Other parts of usbcore will be converted in later patches. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Still the ondemand should be the default governor on a wide range of systems. This patch allows this and lets the governor fallback to the performance governor at cpufreq driver load time, if the driver does not support fast enough frequency switching. Main benefit is that on e.g. installation or other systems without userspace support a working dynamic cpufreq support can be achieved on most systems by simply loading the cpufreq driver. This is especially essential for recent x86(_64) laptop hardware which may rely on working dynamic cpufreq OS support.
