* USB: xhci: Add quirk for Fresco Logic xHCI hardware.Sarah Sharp2009-09-234-23/+148
| | | | | | | | | | | | | | | | | | | | | | | This Fresco Logic xHCI host controller chip revision puts bad data into the output endpoint context after a Reset Endpoint command. It needs a Configure Endpoint command (instead of a Set TR Dequeue Pointer command) after the reset endpoint command. Set up the input context before issuing the Reset Endpoint command so we don't copy bad data from the output endpoint context. The HW also can't handle two commands queued at once, so submit the TRB for the Configure Endpoint command in the event handler for the Reset Endpoint command. Devices that stall on control endpoints before a configuration is selected will not work under this Fresco Logic xHCI host controller revision. This patch is for prototype hardware that will be given to other companies for evaluation purposes only, and should not reach consumer hands. Fresco Logic's next chip rev should have this bug fixed.

* USB: xhci: Handle stalled control endpoints.Sarah Sharp2009-09-233-14/+58
| | | | | | | | | | | | | | | | | | | | | | | When a control endpoint stalls, the next control transfer will clear the stall. The USB core doesn't call down to the host controller driver's endpoint_reset() method when control endpoints stall, so the xHCI driver has to do all its stall handling for internal state in its interrupt handler. When the host stalls on a control endpoint, it may stop on the data phase or status phase of the control transfer. Like other stalled endpoints, the xHCI driver needs to queue a Reset Endpoint command and move the hardware's control endpoint ring dequeue pointer past the failed control transfer (with a Set TR Dequeue Pointer or a Configure Endpoint command). Since the USB core doesn't call usb_hcd_reset_endpoint() for control endpoints, we need to do this in interrupt context when we get notified of the stalled transfer. URBs may be queued to the hardware before these two commands complete. The endpoint queue will be restarted once both commands complete.

* USB: xhci: Support full speed devices.Sarah Sharp2009-09-233-5/+89
| | | | | | | | | | | | | | | | | | Full speed devices have varying max packet sizes (8, 16, 32, or 64) for endpoint 0. The xHCI hardware needs to know the real max packet size that the USB core discovers after it fetches the first 8 bytes of the device descriptor. In order to fix this without adding a new hook to host controller drivers, the xHCI driver looks for an updated max packet size for control endpoints. If it finds an updated size, it issues an evaluate context command and waits for that command to finish. This should only happen in the initialization and device descriptor fetching steps in the khubd thread, so blocking should be fine.

* USB: xhci: Set correct max packet size for HS/FS control endpoints.Sarah Sharp2009-09-231-5/+18
| | | | | | | | | | | | | | | | | Set the max packet size for the default control endpoint on high speed devices to be 64 bytes. High speed devices always have a max packet size of 64 bytes. There's no use setting it to eight for the initial 8 byte descriptor fetch and then issuing (and waiting for) an evaluate context command to update it to 64 bytes for the subsequent control transfers. The USB core guesses that the max packet size on a full speed control endpoint is 64 bytes, and then updates it after the first 8-byte descriptor fetch. Change the initial setup for the xHCI internal representation of the full speed device to have a 64 byte max packet size.

* USB: xhci: Configure endpoint code refactoring.Sarah Sharp2009-09-234-52/+169
| | | | | | | | | | | | Refactor out the code issue, wait for, and parse the event completion code for a configure endpoint command. Modify it to support the evaluate context command, which has a very similar submission process. Add functions to copy parts of the output context into the input context (which will be used in the evaluate context command).

* USB: xhci: Work around for chain bit in link TRBs.Sarah Sharp2009-09-234-4/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Different sections of the xHCI 0.95 specification had opposing requirements for the chain bit in a link transaction request buffer (TRB). The chain bit is used to designate that adjacent TRBs are all part of the same scatter gather list that should be sent to the device. Link TRBs can be in the middle, or at the beginning or end of these chained TRBs. Sections 4.11.5.1 and 6.4.4.1 both stated the link TRB "shall have the chain bit set to 1", meaning it is always chained to the next TRB. However, section 4.6.9 on the stop endpoint command has specific cases for what the hardware must do for a link TRB with the chain bit set to 0. The 0.96 specification errata later cleared up this issue by fixing the 4.11.5.1 and 6.4.4.1 sections to state that a link TRB can have the chain bit set to 1 or 0. The problem is that the xHCI cancellation code depends on the chain bit of the link TRB being cleared when it's at the end of a TD, and some 0.95 xHCI hardware simply stops processing the ring when it encounters a link TRB with the chain bit cleared. Allow users who are testing 0.95 xHCI prototypes to set a module parameter (link_quirk) to turn on this link TRB work around. Cancellation may not work if the ring is stopped exactly on a link TRB with chain bit set, but cancellation should be a relatively uncommon case.

AFAIK the SL811 has only a combined Device Insert/Remove detection bit, therefore use a count to distinguish insert or remove.

I'm not sure if the readings are correct, however - on my 330, the driver reports values between 27 and 41 °C (with core1 being about 8°C hotter than core0, given the same load). Maybe the maximum temperature of 100 °C is wrong for Atom CPUs.

* | | cpuidle: menu governor: reduce latency on exitCorrado Zoccolo2009-09-221-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the state residency accounting and statistics computation off the hot exit path. On exit, the need to recompute statistics is recorded, and new statistics will be computed when menu_select is called again. The expected effect is to reduce processor wakeup latency from sleep (C-states). We are speaking of few hundreds of cycles reduction out of a several microseconds latency (determined by the hardware transition), so it is difficult to measure.

The reason for a reworked governor is that there have been serious performance issues reported with the existing code on Nehalem server systems. To show this I'm sure Andrew wants to see benchmark results: (benchmark is "fio", "no cstates" is using "idle=poll") no cstates current linux new algorithm 1 disk 107 Mb/s 85 Mb/s 105 Mb/s 2 disks 215 Mb/s 123 Mb/s 209 Mb/s 12 disks 590 Mb/s 320 Mb/s 585 Mb/s In various power benchmark measurements, no degredation was found by our measurement&diagnostics team. Obviously a small percentage more power was used in the "fio" benchmark, due to the much higher performance. While it would be a novel idea to describe the new algorithm in this commit message, I cheaped out and described it in comments in the code instead.
