| | | | | | | | | | | | Update the KEYSC driver to make use of threaded IRQs with IRQF_ONESHOT to improve interrupt latency. The driver is using udelay() in the ISR to make sure the hardware has stabilized. Without using interrupt threads this delay may affect the latency of the rest of the system.

* Input: evdev - only signal polls on full packetsJeff Brown2011-04-261-6/+11
| | | | | | | | | | | | | | | | | | This patch modifies evdev so that it only becomes readable when the buffer contains an EV_SYN/SYN_REPORT event. On SMP systems, it is possible for an evdev client blocked on poll() to wake up and read events from the evdev ring buffer at the same rate as they are enqueued. This can result in high CPU usage, particularly for MT devices, because the client ends up reading events one at a time instead of reading complete packets. We eliminate this problem by making the device readable only when the buffer contains at least one complete packet. This causes clients to block until the entire packet is available.

If driver has been configured for ABS coordinates at start it will get XENKBD_TYPE_POS events and then suddenly after restore it'll start getting XENKBD_TYPE_MOTION events, that will be dropped later and they won't get into user-space. Regression was introduced by hunk 5 and 6 of 5ea5254aa0ad269cfbd2875c973ef25ab5b5e9db ("Input: xen-kbdfront - advertise either absolute or relative coordinates"). Driver on restore should ask xen for request-abs-pointer again if it is available. So restore parts that did it before 5ea5254.

(0x1 != 0x55) error in the log. But there's no reason to print this message at KERN_ERR level each time that loop fails, especially since the message telling about the overall selftest failure is printed at KERN_INFO level (on X86). Add an actual error message for non-X86 systems, where a selftest failure is (apparently) more serious. Remove a space in an another error message.

Current uinput restrictions do not allow duplication of these devices and require hacks in userspace to work around this.
