USB: Make file operations structs in drivers/usb const.

2006-09-27T18:58:52+00:00

Making structs const prevents accidental bugs and with the proper debug
options they're protected against corruption.

[PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_private

2006-09-27T15:26:17+00:00

The following patches reduce the size of the VFS inode structure by 28 bytes
on a UP x86.  (It would be more on an x86_64 system).  This is a 10% reduction
in the inode size on a UP kernel that is configured in a production mode
(i.e., with no spinlock or other debugging functions enabled; if you want to
save memory taken up by in-core inodes, the first thing you should do is
disable the debugging options; they are responsible for a huge amount of bloat
in the VFS inode structure).

This patch:

The filesystem or device-specific pointer in the inode is inside a union,
which is pretty pointless given that all 30+ users of this field have been
using the void pointer.  Get rid of the union and rename it to i_private, with
a comment to explain who is allowed to use the void pointer.  This is just a
cleanup, but it allows us to reuse the union 'u' for something something where
the union will actually be used.

[PATCH] UHCI: remove ISO TDs as they are used

2006-06-21T22:04:12+00:00

This patch (as690) does the same thing for ISO TDs as as680 did for
non-ISO TDs: free them as they are used rather than all at once when an
URB is complete.  At the same time it fixes a minor buglet (I'm not
aware of it ever affecting anyone): An ISO TD should be retired when its
frame is over, regardless of whether or not the hardware has marked it
inactive.

[PATCH] UHCI: store the period in the queue header

2006-06-21T22:04:12+00:00

This patch (as689) stores the period for periodic transfers (interrupt
and ISO) in the queue header.  This is necessary for proper bandwidth
tracking (not yet implemented).  It also makes the scheduling of ISO
transfers a bit more rigorous, with checks for out-of-bounds frame
numbers.

[PATCH] UHCI: use integer-sized frame numbers

2006-06-21T22:04:12+00:00

This patch (as687) changes uhci-hcd to keep track of frame numbers as
full-sized integers rather than 11-bit values.  This makes them a lot
easier to handle and makes it possible to schedule beyond a 2-second
window, should anyone ever want to do so.

[PATCH] UHCI: Reimplement FSBR

2006-06-21T22:04:11+00:00

This patch (as683) re-implements Full-Speed Bandwidth Reclamation (FSBR)
properly.  It keeps track of which endpoint queues have advanced, and
when none have advanced for a sufficiently long time, FSBR is turned
off.  The next TD on each of the non-moving queues is modified to
generate an interrupt on completion, so that FSBR can be re-enabled as
soon as the hardware starts to make some progress.

[PATCH] UHCI: Remove non-iso TDs as they are used

2006-06-21T22:04:11+00:00

This patch (as680) frees non-isochronous TDs as they are used, rather
than all at once when an URB is complete.  Although not a terribly
important change in itself, it opens the door to a later enhancement
that will reduce storage requirements by allocating only a limited
number of TDs at any time for each endpoint queue.

[PATCH] USB: UHCI: store the endpoint type in the QH structure

2006-06-21T22:04:10+00:00

This patch (as675) simplifies uhci-hcd slightly by storing each endpoint's
type in the corresponding Queue Header structure.

[PATCH] UHCI: improve debugging code

2006-03-20T22:49:57+00:00

This patch (as626) makes some improvements to the debugging code in
uhci-hcd.  The main change is that now the code won't get compiled if
CONFIG_USB_DEBUG isn't set.  But there are other changes too, like
adding a missing .owner field and printing a debugging dump if the
controller dies.
