2012-11-24libpayload: Fix interrupt-queue cleanup for OHCINico Huber
We have to free TDs more carefully if they have been processed by the controller yet. The current code tries to force the controller to post them back to the done queue, but that seems wrong. We can't be sure, when they get written back. This resulted in leaking TDs with an invalid reference to a freed interrupt queue. The new approach: Mark the interrupt queue to be destroyed and handle the freeing later, when the controller posted the last TD to the done queue.

2012-11-24libpayload: Implement correct interrupt-queue linking for UHCINico Huber
The linking of interrupt queues into UHCI controller's framelist (in uhci_create_intr_queue()) was incomplete. The implementation of uhci_destroy_intr_queue() was even worse, looking like it wanted to clean up more than uhci_create_intr_queue() did. This patch follows the simple approach that we used for OHCI and EHCI: Each slot in the framelist holds only one interrupt queue. Therefore, we have to look for free slots each time we want to link an interrupt queue into the framelist. In return, we have a much simpler structured framelist. With this, USB devices using interrupt transfers (e.g. keyboards) can be detached cleanly from UHCI controllers. Also, more than one of such devices can be attached without further risk.

2012-11-15libpayload: Always use virtual pointers in struct sysinfo_tNico Huber
We had mixed virtual and physical pointers in struct sysinfo_t. Some being virtual by accident which led to problems when we tried to reinitialize lib_sysinfo after relocating FILO (to get intentionally virtual pointers valid again). I guess this didn't cause much trouble before, as lib_get_sysinfo() was always called with physical addresses being equal to their virtual counterparts. For FILO, two possibilities seem practical: Either, have all pointers in struct sysinfo_t physical, so relocation doesn't hurt. Or, have all pointers virtual and call lib_get_sysinfo() again after relocation. This patch goes the latter way, changing the following pointers for situations where virtual pointers differ from physical: .extra_version .build .compile_time .compile_by .compile_host .compile_domain .compiler .linker .assembler .cb_version .vdat_addr .tstamp_table .cbmem_cons .mrc_cache We could also just correct the accidentally virtual pointers. But, IMO, this would lower the risk of future confusion. Note 1: Looks like .version gets never set. Note 2: .option_table and .framebuffer were virtual pointers but treated like physical ones. Even in FILO, this led to no problems as they were set before relocation.

So move the initialization part to a new function, uhci_reinit(), which get's exported through a new entry in hci_t: hci_t.init(). Warning: This breaks code that relies on the current, special, counterintuitive behaviour of uhci_reset(). If one wants a working host controller after calling hci_t.reset(), he should call hci_t.init() afterwards.

2012-06-21libpayload: Add support for interrupt transfers in OHCINico Huber
This adds support for usb interrupt transfers to the OHCI driver. Basically this enables support for HID keyboard devices. For each interrupt transfer endpoint, two queues of transfer descriptors (TDs) are maintained: the first with initialized TDs is linked to the periodic schedule of the host controller (HC), the second holds processed TDs which will be polled by the usb class driver. The HC moves processed TDs from its schedule to a done queue. We periodically fetch all TDs from the done queue, to put them on the queue associated with the endpoint, where they can be polled from. Fully processed TDs (i.e. which have gone throuch all of this) will be reinitialized and put on the first queue again.

This adds correct processing of the done queue of the OHCI host controller (HC). We will always process the done queue after a control or bulk transfer. Unfortunately, it's hard to tell when the HC will write out the done queue, so we have do free the transfer descriptors later and have to allocate them one by one. To distinguish different types of TDs (e.g. async vs. interrupt transfers) on the done queue, they are flagged in the lsb of there .config field. We can utilize this bit for our own purpose, as it's reserved and the host controller won't interpret it and preserves its state.

2011-11-10libpayload: Fix handling of CAPS LOCK key on PS/2 keyboardsPatrick Georgi
The PS/2 keyboard driver set and reset the caps LED to show the keyboard status. Unfortunately, that configuration happens over the same path used to transmit keypresses. In face of certain error conditions, the keyboard stopped working. This change makes keyboard handling more robust.
