2012-04-05simple_open: automatically convert to simple_open()Stephen Boyd1-8/+1
Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-12-22uwb: use print_hex_dump()David Vrabel1-20/+1
Use print_hex_dump() instead of the home-grown dump_bytes(). Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-12-12uwb: improved MAS allocator and reservation conflict handlingStefano Panella1-23/+26
Greatly enhance the MAS allocator: - Handle row and column reservations. - Permit all the available MAS to be allocated. - Follows the WiMedia rules on MAS selection. Take appropriate action when reservation conflicts are detected. - Correctly identify which reservation wins the conflict. - Protect alien BP reservations. - If an owned reservation loses, resize/move it. - Follow the backoff procedure before requesting additional MAS. When reservations are terminated, move the remaining reservations (if necessary) so they keep following the MAS allocation rules.

2008-11-26wusb: add debug files for ASL, PZL and DI to the whci-hcd driverDavid Vrabel1-0/+13
Add asl, pzl and di debugfs files to uwb/uwbN/wusbhc for WHCI host controller. These dump the current ASL, PZL and DI buffer. Signed-off-by: David Vrabel <david.vrabel@csr.com>

2008-11-19uwb: add basic radio managerDavid Vrabel1-3/+23
The UWB radio manager coordinates the use of the radio between the PALs that may be using it. PALs request use of the radio with uwb_radio_start() and the radio manager will start beaconing if its not already doing so. When the last PAL has called uwb_radio_stop() beaconing will be stopped. In the future, the radio manager will have a more sophisticated channel selection algorithm, probably following the Channel Selection Policy from the WiMedia Alliance when it is finalized. For now, channel 9 (BG1, TFC1) is selected. The user may override the channel selected by the radio manager and may force the radio to stop beaconing. The WUSB Host Controller PAL makes use of this and there are two new debug PAL commands that can be used for testing. Signed-off-by: David Vrabel <david.vrabel@csr.com>

2008-11-04uwb: add commands to add/remove IEs to the debug interfaceStefano Panella1-1/+19
Add the commands UWB_DBG_CMD_IE_ADD and UWB_DBG_CMD_IE_RM to the debug interface and make them call uwb_rc_ie_add() and uwb_rc_ie_rm(). Signed-off-by: Stefano Panella <stefano.panella@csr.com> Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-10-28uwb: reference count reservationsDavid Vrabel1-3/+10
Reference counting the struct uwb_rsv's is safer and easier to get right than the transferring ownership of the structures from the PAL to reservation manager. This fixes an oops in the debug PAL after a reservation timed out. Signed-off-by: David Vrabel <david.vrabel@csr.com>
