New version: 4.1.0, 8th March 2014A stable and bugfix release with new drivers. I recommend all 4.x users update.
Human readable changelog:- Zero stats will now show the correct average hashrate per device.
- Fixed the high CPU usage which led to eventually slowing down of hashrates over time.
- Respect the -Q value by slightly changing its meaning to be the highest value it can reach, defaulting to 9999. Regular users need not do anything with this value.
- Fixed the hex32 api values (currently only hashfast serial number) returning invalid JSON over the API.
- New driver - BXM for an upcoming two bitfury chip USB stick courtesy of Goodney, along with an overclocking option with --bxm-bits
- New driver - merged the bitmain S1 driver
- Try harder to shut cgminer down fully on quit/restart/--shares end.
- Fix cgminer shutting down and hanging when a grossly invalid stratum message is received.
- Fix cointerra hashrate display to show a share based hashrate so that the displayed hashrate should match the pool hashrate.
- Hashfast improvements:
. Dramatic decrease in CPU usage for all existing firmwares since they don't internally nroll time.
. Latest version now works with older 0.2 firmwares
. Only decrease the clockspeed if a device fails in less than an hour at its current clockspeed
. New feature allows per-device settings:
--hfa-options <arg> Set hashfast options name:clock (comma separated)
This command allows you to set options for each discrete hashfast device by
its name (if the firmware has naming support, i.e. version 0.3+). Currently
this takes only one option, the clock speed, although future options may be
added.
e.g.:
--hfa-options "rabbit:650,turtle:550"
Would set a device named rabbit to clock speed 650 and the one named turtle to
550. Starting the device at a speed where it is most stable will give more
reliable hashrates long term and prevent it interacting with other devices,
rather than depending on the clockdown feature in cgminer.
- Other low level bugfixes and improvements and anticipatory changes.
Full changelog:- Correct fix for dev start time being adjusted for stat zeroing.
- Make per device stats work for average after a stat zeroing.
- Add an hfa-options command line that allows the clockspeed to be chosen per
device by name comma separated, with a function that can be expanded with more
options in the future.
- Off by one drv_rolllimit check against jobs
- Free the work that may be lost, leaking memory, in a failed hfa_send_frame
- Roll the ntime for work within the hfa driver for firmware we know doesn't do
it internally as an optimisation.
- Export the roll_work function to be usable by driver code and make it
compatible with rolling stratum work.
- Make opt_queue be respected as a maximum value for staged items.
- Disable mistakenly enabled lock tracking.
- api version update for HEX32
- api.c - HEX32 type needs quotes
- Disable the MAX_CLOCK_DIFF check for newer hashfast firmwares since it's not
required.
- Store the hardware and firmware revision in the info struct for easy use in
the hfa driver.
- Only decrease the hfa clock rate if the device has been running for less than
an hour before dying.
- Change lack of op name response message in hfa driver
- Check for lost devices at every write/read in hfa_detect_common
- Make bxm bits configurable.
- Move avalon2 options to ~alphabetic position in help.
- Do a shutdown routine on bxm close.
- Provide support for 2 chips in libbitfury sendhashdata and enable the 2nd chip
on BXM devices.
- Remove unnecessary opayload and newbuf members of bitfury info struct.
- Add an spi add fasync command.
- Cope with older hfa firmware not even responding to op_name.
- Forcibly kill everything silently with an exit code of 1 should we fail to
cleanly shut down and use a completion timeout for the __kill_work in
app_restart.
- Make __kill_work itself also be a completion timeout.
- Generalise more of libbitfury for more reuse in both nf1 and bxm drivers.
- Remove redundant init components of bxm driver.
- Set default osc6 bits on bxm to 50
- Enable the transaction translator emulator for bxm devices and use a dummy spi
tx the size of a normal payload.
- Store usb11 and tt flags as booleans in cgusbdev allowing them to be
discretely enabled as well as detected by the device data.
- Add bxm scan function and check spi txrx returns only as much as sent.
- Add init sequence to bxm detect one.
- Add a bxm specific txrx function for spi transfers.
- Add bxm close to bitfury shutdown switch.
- Add reset/purge/cshigh/low sequence to bxm init
- Add bitmode init to bxm open sequence.
- Add initial bxm opening sequence for detect one.
- Add identifiers for bxm bitfury devices.
- Clean up parse_method
- More gracefully break out of parse_notify on a corrupted hex string error,
checking the return value of all hex2bin conversions and being consistent with
using stack memory. Fix an unlocking error in cases of failure.
- AntS1 - add detection information to usbutils
- Enable Bitmain Ant S1 code and make it conform to cgminer requirements
- Make the cointerra displayed hashrate based on valid share generation.
- Convert and update values shown in the cointerra api output.
- Export the api_add_int16 function.
- Use a custom mystrstr function in cointerra driver.
- Add api_add_int16 to API functions.
- Add support for Bitmain Multi Chain and Single Chain and optimize the
efficiency
- Add support for bitmain devices
- Perfect function of BitMain Multi Chain
- Add support for Bitmain Multi Chain and Single Chain and optimize the
efficiency
- Add support for bitmain devices
