cgminer 3.5 is now available

cgminer has just been updated to version 3.5 today. cgminer is a command line based mining application which allows you to mine crypto-currencies. See our Mining guide on how to get started.

You can download the latest version here: http://ck.kolivas.org/apps/cgminer/

Complete changelog information for the new version is outlined below:

- Add magic init sequence required on BF1 devices to get them mining on windows.
- usbinfo.devlock is only ever write locked so convert it to a mutex
- Icarus remove unneeded opt_debug tests due to applog being a macro
- Icarus – CMR shouldn’t wait the full timeout due to handle sharing
- We should only yield once in cg_wunlock
- Provide a function to downgrade a cglock from a write lock to an intermediate
- Deuglify use of _PARSE_COMMANDS macro expansions.
- Deuglify use of usb parse commands macro in usbutils.
- Use the driver add commands macros in api.c to avoid individually listing
- Separate out asic fpga and opencl drivers in the driver parse commands macro
for use individually as needed.
- Use macro expansion in usb_find_devices to avoid explicitly listing them all.
- Use macro expansion to iterate over all the drivers without explicitly writing
them out in usbutils.c
- Iterate over the bitfury offsets in order of decreasing likelihood.
- Reattach the kernel driver on linux on usb_uninit.
- Attach the kernel driver on failure to usb init on linux.
- libusb kernel driver operations are only available on linux.
- There is no need to get the external prototypes for drivers in cgminer.c any
- Remove unnecessary gpu_threads initialisation.
- Put avalon last in the sequence of adding drivers to prevent it trying to
claim similar chip devices on startup.
- Use macro expansion to iterate over all device drivers without needing to
explicitly code in support in all places. Pass a hotplug bool to the detect()
function to prevent opencl trying to hogplug GPUs.
- Forward declare all device drivers in miner.h avoiding the need to export them
everywhere else.
- Add a noop function for driver detect when it’s missing.
- Reuse the DRIVER_ macros to avoid having yet another definition for DRV_
- Use macro expansion to generate extern device_drv prototypes.
- Create a macro list of drivers to enable easier addition of further drivers.
- There is no point setting the BF1 preferred packet size to the maximum since
it will do so automatically.
- icarus ensure all cmr interfaces are initialised properly
- usbutils – fix USBDEBUG warnings
- Remove unnecessary steps in communicating with BF1 and just use USB interface
- usbutils – usb_bulk_transfer fix the buf/data fix
- usb_bulk_transfer – use the allocated buffer
- Set preferred packet sizes per interface on BF1.
- usbutils allow PrefPacketSize per endpoint
- Remove magic control sequences on open/close on BF1 and just flush the read
- Check return codes in getinfo and reset and fail as needed in BF1.
- Check return code for bitfury_open and release resources properly on failed
- Abstract out flushing of interrupt reads in BF1 devices.
- Perform interrupt read after close message on BF1 as per serial close.
- Perform interrupt read flush as per serial open on BF1 devices.
- Add information for 2nd USB interface on BF1 devices and choose interface 1
for bulk transfers.
- usbutils – bulk transfer copy test fix
- usbutils – add USBDEBUG for usb_bulk_transfer
- Add more read_ii variants to usbutils.
- Name remainder of BFU usb commands used.
- Use submit_tested_work in bitfury driver to avoid unnecessarily re-testing the
work for validity.
- Abstract out work submission once it’s been tested, to be used by drivers that
do their own internal validity testing.
- Store the hash2 array in struct work for further reuse.
- usbutils – which_intinfo not requried
- Use the test_nonce function within submit_nonce and store the uint32
corresponding to hash2 37 for further use.
- usbutils – interfaces must all be on one handle – ep implies the interface
- avalon stats use exact type
- Only set share diff if we’ve confirmed it’s a share first.
- Update ASIC-README for bitfury devices.
- Use an array of offsets when checking nonces in bitfury_checkresults
- Limit the duration we wait for reads in BF1 based on time already elapsed to
account for other delays such as work restart messages or out of work.
- Minimise size of serial string we copy in BF1 stats to avoid overflow.
- Implement basic API stats for BF1 and increase array of results to check for
the rare straggling result.
- Space debug output for bf1 to separate from numerals.
- Abstract out the bitfury open close and reset functions and use them on
- Rename BF1 devices BF1
- Check for work restart, breaking out early after usb reads in BF1.
- Do not lose the first sets of results from BF1.
- There is no point checking for results from the next round of work on BF1.
- Last result returned by BF1 is an end of results marker so ignore it.
- restart_wait should return 0 if thr_restart is true.
- Remove unused code by bitfury driver since current driver uses serialised
- Meter out return of estimated hashes in BF1 to smooth out visible hashrate.
- Optimise inner scanhash loop for bf1.
- Add yet another backup work for triple buffering of work in bf1 to account for
extra late results returned and don’t check nonce offsets which appear to never
- Name the work request and result usb commands for BF1
- Define a mandatory upper limit to waiting for reset and data on BF1 based on
full nonce duration.
- Decrease usb buffering to verbose logging.
- Add in first draft for a serialised work model sending/receiving data for BF1
- Add complete close sequence to bf1 as it happens on serial.
- Provide a bitfury identify function for bf1.
- Reliably extract BF1 information at startup and reset the device.
- Add commands for getting BF1 bitfury info
- Add magic BF1 bitfury open and close control sequences.
- Add BF1 detection code to bitfury driver.
- Create basic placeholders for bitfury driver code.
- Add bf1 device information to usbutils to enable device detection.
- Add basic defines for building for bitfury devices.
- Add redfury device to udev rules.
- avalon: display the FPGA controller version on API
- pool_active uninitialised_var rolltime
- Use macro expansion to only need to define usb enums and commands in one
- usbutils saving incorrect overflow buffer
- ignore libusb.la and *.lo on linux
- icarus support CMR with no extensions
- usbtils – interfaces dont work yet in libusb windows so disable for that only
- Provide a –disable-libcurl config option to build support for stratum mining
- Fix the api-example.c compile under Linux
- usbutils – only release the device once – for the first intinfo
- usbutils set_interface is no longer valid
- ubsutils interfaces much each have their own handle
- usbutils kernel_detach should use the interface number
- usbutils – allow the driver to change which_intinfo
- Reset quotas on load balance for all pools at the same time to avoid running
out during selection and unintentionally dropping to fallback.
- Break out of select pool from a common point for appropriate debug messages
and to avoid further tests.
- usbutils correct/reverse CMR product numbers
- usbutils specifically track handles and interfaces
- change drivers to use usb_interface() – required for multi interface change
- usbutils – allow a device to use multiple interfaces (and better var names)
- Cast -1 to (char) to cope with different default char types on ARM.
