More bugfixes for the 3.2 series. Hopefully getting close to being stable enough to not call 3.1.1 the latest stable version. USB3 hubs with multiple devices may still be problematic - please give feedback! For those who have not yet moved to the 3.2 series yet, I will remind you to please take note that the USB device driver model in cgminer has completely changed and windows users should use zadig to convert their selected USB devices to the WinUSB driver, and linux users will need to set their permissions to be able to use the usb devices as regular users. All the details are in the FGPA-README and ASIC-README files. No, this does not include a driver for the newly finished BFL singles (or doubles as I call them) since we do not have access to said hardware yet.
Human readable changelog:
- More debugging output.
- Hopefully fixed the stratum disconnection hangs on windows!
- Found numerous causes for devices dropping out on USB becoming zombies and rectified them so it should happen far less frequently now.
- Fixed numerous crashes with certain logging output on windows during hotplug/shutdown.
- Found a limitation on single core CPU devices (eg the router that drives the Avalon) and have worked around poor performing heavily threaded lock usage for such hardware, leading to less CPU usage, less delays and slightly higher hashrates.
- Zombies will now not fill the screen if they happen repeatedly - only the most active devices ever encountered will show on screen so if you don't change the number of devices and they go zombie and re-hotplug, you will not see their zombies while running, only on shutdown or API stats.
- Newly hotplugged devices show their average hashrate from when they were started rather than when cgminer was started.
- A lot more usb1.1 devices (most lancelot devices) will work on usb3 hubs now.
- Mac OSX build fixes.
- The efficiency value will no longer show for pools unless they are using the old getwork communication protocol.
- Avalon improvements to avoid duplicate shares/idle devices.
- Nominal cutoff temperature set for BFL ASIC devices.
- Don't give write/read fail errors when shutting down on OSX.
- BFL SC 5GH devices that failed to initialise due to being slow to respond should start now.
- Fixes for numerous possible crashes on hotplug/unplug.
- Numerous low level fixes.
Full changelog:
- Record and report USB pipe errors via API stats
- Suspend stratum connections when we know they've failed and don't try to recv
data from them once the socket no longer exists.
- Pipe error is quite common on usb3 so drop logging to verbose level only.
- ocl.c fix applog warnings on windows
- applog/quit fix GPU errors created
- usbutils - DEVLOCK other usbdev access
- applog usb device list can be > LOGBUFSIZ
- fix windows log warnings
- logging remove extra added
- remove varargs from logging/quit/in general as much as possible
- Don't yield when downgrading a cg ilock.
- Don't yield on grabbing the read lock variant of cglocks.
- Off by one error in device count for display.
- Don't display devices beyond the most_devices count in the curses status.
- Only display as many device rows as the maximum live existed at any time.
- usb lock out use cg locks
- usb lock out transfers during open/close
- Add error message to libusb pipe error
- Differentiate libusb control transfer pipe errors from transfer errors since
they're not fatal.
- Create a usb_bulk_transfer wrapper for libusb_bulk_transfer to cope with pipe
errors.
- Only show efficiency in pool information for pools that don't support local
work generation.
- Create a pool_localgen bool function for testing when a pool can generate work
locally.
- ignore file that is generated on Macs
- compile unix code on Mac OS X fixes not finding the config file in $HOME
- Use mining start time for device MH/U calculations
- Decrease the sleep duration before reading in avalon to not let the read
buffer overflow.
- Failure to read and write on pseudo semaphores on apple happens routinely on
shut down so should not be a quit error, just a warning.
- Unlock usb dev lock in the same place in usbutils.
- Sleep if the avalon buffer is empty and we've requested a read to allow the
write thread to take precedence.
- Yield after releasing a lock in case we are on a device with limited CPU
resources.
- Add the cgpu_info structure before avalon reset.
- Tidy up DEVLOCK/UNLOCK to have consistent use of the pstate variable without
needing brace level match.
- Icarus driver elaspsed timeout shouldn't be just USB I/O
- usbutils avoid leaving devlock locked when thread cancelled
- MMQ fix nodev failure caused by changes
- ubsutils lock all access to nodev and cgusb
- USB make device_path handled by usbutils
- tidy up free in device detect functions
- USB control creation and free of cgpu
- Add FAQ regarding Work Utility.
- Throttling the BFLSC at 80 seems to prevent generating garbled responses of
higher temps.
- Return after failed bin2hex conversion in bflsc.
- Demote failed hex2bin result to LOG_INFO and check return result in
driver-bflsc to avoid doing find_work_by_midstate.
- Set BFLSC fan speed coarsely to keep it under 60 or auto as per specs saying
it tries to stay below 60.
- Limit usbutils LATENCY_STD to 32ms to keep transfers under 512 bytes.
- Move macro definition to bflsc driver
- Use a longer timeout for retrieving bflsc details.
- Add a usb_read_ok_timeout wrapper to cope with slow init'ing devices.
- cgsem_post after creating the thread info
- Fix build.
- Use cgsem structures instead of the flaky pings in the work queue to start
mining threads and remove the unused thr_info_freeze function.
