2006-01-04[PATCH] USB: UHCI: edit some commentsAlan Stern
This patch (as615b) edits a large number of comments in the uhci-hcd code, mainly removing excess apostrophes. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-01-04[PATCH] USB: UHCI: change uhci_explen macroAlan Stern
This patch (as616) changed the uhci_explen macro in uhci-hcd.h so that it now accepts the desired length, rather than length - 1 with special handling for 0. This also fixes a minor bug that would show up only when a driver submits a 0-length bulk URB. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-10-28[PATCH] USB: UHCI: Spruce up some commentsAlan Stern
This patch (as570) changes some comments in the uhci-hcd header file and removes an unused declaration (something I forgot to erase in an earlier patch).

2005-10-28[PATCH] USB: UHCI: Split apart the physical and logical framelist arraysAlan Stern
This patch (as563) splits the physical and logical framelist arrays in uhci-hcd into two separate pieces. This will allow slightly better memory utilization, since each piece is no larger than a single page whereas before the whole thing was a little bigger than two pages. It also allows the logical array to be allocated in non-DMA-coherent memory. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-10-28[PATCH] USB: UHCI: Remove unused fields and unneeded tests for NULLAlan Stern
This patch (as562) removes from the uhci-hcd driver a few unused fields and some unnecessary tests against NULL and assignments to NULL. In fact it wasn't until fairly recently that the tests became unnecessary. Before last winter it was possible that the driver's stop() routine would get called even if the start() routine returned an error, but now that can't happen. Hence there's no longer any need to check for partial initialization. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-09-12[PATCH] USB UHCI: remove the FSBR kernel timerAlan Stern
This patch (as558) removes from the UHCI driver a kernel timer used for checking Full Speed Bandwidth Reclamation (FSBR). The checking can be done during normal root-hub polling; it doesn't need a separate timer. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-06-27[PATCH] UHCI: Don't store device pointer in QH or TDAlan Stern
This patch simplifies the uhci-hcd driver by removing the device pointer currently stored in the QH and TD structures. Those pointers weren't being used for anything other than to increment the device's reference count, which is unnecessary since the device is used only when an URB completes, and outstanding URBs take their own reference to the device. As a useful side effect, this change means that uhci-hcd no longer needs to have the root-hub device available in the start routine.

2005-06-27[PATCH] USB UHCI: Use root-hub IRQs while suspendedAlan Stern
This patch, which has as478b as a prerequisite, enables the uhci-hcd driver to take advantage of root-hub IRQs rather than polling during the time it is suspended. (Unfortunately the hardware doesn't support port-change interrupts while the controller is running.) It also turns off the driver's private timer while the controller is suspended, as it isn't needed then. The combined elimination of polling interrupts and timer interrupts ought to be enough to allow some systems to save a noticeable amount of power while they are otherwise idle.

2005-06-27[PATCH] USB UHCI: Add root-hub suspend/resume supportAlan Stern
This patch implements (finally!) separate suspend and resume routines for the root hub and the controller in the UHCI driver. It also changes the sequence used to reset the controller during initial probing, so as to preserve the existing state during a Resume-From-Disk. (This new sequence is what should be used in the PCI Quirks code for early USB handoffs, incidentally.) Lastly it adds a notion of the controller being "inaccessible" while in a PCI low-power state, when normal I/O operations shouldn't be allowed.

2005-06-27[PATCH] USB UHCI: Add root hub statesAlan Stern
This patch starts making some serious changes to the UHCI driver. There's a set of private states for the root hub, and the internal routines for suspending and resuming work completely differently, with transitions based on the new states. Now the driver distinguishes between a privately auto-stopped state and a publicly suspended state, and it will properly suspend controllers with broken resume-detect interrupts instead of resetting them.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
