2019-08-21media: mceusb: fix (eliminate) TX IR signal length limitA Sun1-138/+196
Fix and eliminate mceusb's IR length limit for IR signals transmitted to the MCE IR blaster ports. An IR signal TX exceeding 306 pulse/space samples presently causes -EINVAL return error. There's no such limitation nor error with the MCE device hardware. And valid IR signals exist with more than 400 pulse/space for the control of certain appliances (eg Panasonic ACXA75C00600 air conditioner). The scope of this patch is limited to the mceusb driver. There are still IR signal TX length and time constraints that related modules of rc core (eg LIRC) impose, further up the driver stack. Changes for mceusb_tx_ir(): Converts and sends LIRC IR pulse/space sequence to MCE device IR pulse/space format. Break long length LIRC sequence into multiple (unlimited number of) parts for sending to the MCE device. Reduce kernel stack IR buffer size: 128 (was 384) Increase MCE IR data packet size: 31 (was 5) Zero time LIRC pulse/space no longer copied to MCE IR data. Eliminate overwriting the source/input LIRC IR data in txbuf[]. Eliminate -EINVAL return; return number of IR samples sent (>0) or MCE write error code (<0). New mce_write() and mce_write_callback(): Implements synchronous blocking I/O, with timeout, for writing/sending data to the MCE device. An unlimited multipart IR signal sent to the MCE device faster than real time requires flow control absent with the original mce_request_packet() and mce_async_callback() asynchronous I/O implementation. Also absent is TX error feedback. mce_write() combines and replaces mce_request_packet() and mce_async_callback() with conversion to synchronous I/O. mce_write() returns bytes sent (>0) or MCE device write error (<0). Debug hex dump TX data before processing. Rename mce_async_out() -> mce_command_out(): The original name is misleading with underlying synchronous I/O implementation. Function renamed to mce_command_out(). Changes in mceusb_handle_command(): Add support for MCE device error case MCE_RSP_TX_TIMEOUT "IR TX timeout (TX buffer underrun)" Changes in mceusb_dev_printdata(): Changes support test and debug of multipart TX IR. Add buffer boundary information (offset and buffer size) to TX hex dump. Correct TX trace bug "Raw IR data, 0 pulse/space samples" Add trace for MCE_RSP_TX_TIMEOUT "IR TX timeout (TX buffer underrun)" Other changes: The driver's write to USB device architecture change (async to sync I/O) is significant so we bump DRIVER_VERSION to "1.95" (from "1.94").

2019-07-22media: mceusb: USB reset device following USB clear halt errorA Sun1-12/+55
This patch schedules a USB reset device call following a USB clear halt error. The issues solved, and patch implementation, are similar to those found in drivers/hid/usbhid/hid-core.c. As seen on very rare occasions approximately one time per month (mceusb device 2304:0225 in this sample) Jul 27 2018 15:09:39 [59388.696941] mceusb 1-1.1.2:1.0: Error: urb status = -32 (RX HALT) [59388.698838] mceusb 1-1.1.2:1.0: rx clear halt error -32 the device can get into RX or TX HALT state where usb_clear_halt() also fails and also returns -EPIPE (HALT/STALL). After which, all further mceusb device control and data I/O always fail with HALT/STALL. Subsequently, the entire mceusb device no longer functions. Cause and problem replication conditions remain unknown. Further troubleshooting reveals usb_reset_device() restores mceusb device operation. Patch test 1: Hot unplugging the mceusb device triggers USB RX HALT and USB clear halt errors. A mceusb_dev_disconnect() call follows unplug. This patch's reset device call invokes an extra mceusb_dev_probe() mceusb_dev_disconnect() cycle, before the mceusb driver detaches. The additional probe/disconnect verifies the patch's device reset code executed. But note this patch is for USB clear halt error cases not caused by unplugging the mceusb device. Patch test 2: Simulate a RX HALT and a clear halt error with instrumented code in the driver.

2019-06-10media: ttpci: use rc-core for the IR receiverSean Young1-0/+1
The IR protocol can now only be set via the rc protocols sysfs file rather than via module parameters or a custom procfs file. So, it is no longer necessary to periodically check for protocol changes. The IR_RCMM protocol does not decode the Philips RC-MM protocol (12, 24 or 32 bit variants) or any protocol rc-core can encode, so this is marked RC_PROTO_UNKNOWN. Tested on Technotrend/Hauppauge WinTV Nexus-S rev2.1, which comes with a small black hauppauge remote.

This feature greatly improves BPF speed on 32-bit architectures. From Jiong. 4) cgroups will now auto-detach bpf programs. This fixes issue of thousands bpf programs got stuck in dying cgroups. From Roman. 5) new bpf_send_signal() helper, from Yonghong. 6) cgroup inet skb programs can signal CN to the stack, from Lawrence. 7) miscellaneous cleanups, from many developers. ==================== Signed-off-by: David S.
