|
- hexstr is too small in test_work_current |
|
|
|
|
- Windows uses errno for WSAETIMEDOUT |
|
|
|
|
- Convert the usb callback function to using cgsem_t timed waits to avoid race |
|
|
|
|
conditions with conditionals/mutexes. |
|
|
|
|
- Give correct return code in cgsem_mswait |
|
|
|
|
- Check for correct timeout error in cgsem_mswait |
|
|
|
|
- Fix util.h exports for cgsem_mswait |
|
|
|
|
- Implement a generic cgsem_mswait similar to sem_timedwait |
|
|
|
|
- Use the one LIBUSB_ERROR_TIMEOUT for cancelled transactions since this error |
|
|
|
|
is explicitly tested for in various drivers. |
|
|
|
|
- Do not use locking on usb callback function pthread signalling to prevent |
|
|
|
|
deadlock with libusb's own event lock. |
|
|
|
|
- Use a write lock when performing any USB control transfers to prevent |
|
|
|
|
concurrent transfers. |
|
|
|
|
- Free a libusb transfer after we have finished using it to avoid a dereference |
|
|
|
|
in usb_control_transfer |
|
|
|
|
- Do not perform bfi int patching for opencl1.2 or later. |
|
|
|
|
- Although async transfers are meant to use heap memory, we never return before |
|
|
|
|
the transfer function has completed so stack memory will suffice for control |
|
|
|
|
transfers, fixing a memory leak in the process. |
|
|
|
|
- klondike - correct/reverse min/max stats |
|
|
|
|
- api incorrect message name |
|
|
|
|
- klondike - use a link list queue rather than a circular buffer - and add |
|
|
|
|
timing stats |
|
|
|
|
- Use a timeout with usb handle events set to a nominal 200ms and wait for the |
|
|
|
|
polling thread to shut down before deinitialising libusb. |
|
|
|
|
- Use stack memory for hex used in stratum share submissions. |
|
|
|
|
- Use stack memory in test_work_current, avoiding a malloc/free cycle each time. |
|
|
|
|
- Provide a lower level __bin2hex function that does not allocate memory itself. |
|
|
|
|
- Convert the bitfury driver to use the hash_driver_work version of hash_work. |
|
|
|
|
- Add a hash_driver_work function to allow for drivers that wish to do their own |
|
|
|
|
work queueing and management. |
|
|
|
|
- Convert all usb control transfers to asynchronous communication with our own |
|
|
|
|
timeout management as well. |
|
|
|
|
- Klondike - increase circular read buffer size |
|
|
|
|
- Klondike - extra zero value and range checking in temp conversion |
|
|
|
|
- klondike - display MHz also |
|
|
|
|
- Make pthread conditional timeouts handle all bulk usb transfer timeouts |
|
|
|
|
performing libusb_cancel_transfer, disabling timeouts within libusb itself. |
|
|
|
|
- Avoid calling get_statline_before on exit to avoid trying to use it on drivers |
|
|
|
|
in an indeterminate state. |
|
|
|
|
- Avoid calling get_statline on exit. |
|
|
|
|
- Add a small amount to the usb timeout before cancelling to allow for a regular |
|
|
|
|
usb polling interval to pass. |
|
|
|
|
- Do not attempt to clear a usb halt before sending the cancel message since all |
|
|
|
|
transfers should normally be cancelled before attempting to clear a halt |
|
|
|
|
condition, and only change the return message to a timeout if it's consistent |
|
|
|
|
with a cancellation. |
|
|
|
|
- Retry up to USB_RETRY_MAX times to clear a halt condition before failing. |
|
|
|
|
- Show the error number as well as the description in erroring bulk transfers. |
|
|
|
|
- Drop logging level for failed to connect to stratum to verbose mode only since |
|
|
|
|
we hit it regularly. |
|
|
|
|
- We are always dependent on libusb handling events so use the blocking |
|
|
|
|
libusb_handle_events in the polling thread and use a bool to know if we should |
|
|
|
|
continue polling. |
