Version 2.4.4 - July 1, 2012
- Fix builds on non gnu platforms.
- api.c ensure old mode is always available when not using --api-groups + quit()
on param errors
- Implement rudimentary X-Mining-Hashrate support.
- Detect large swings in temperature when below the target temperature range and
change fan by amounts dependant on the value of tdiff.
- Adjust the fanspeed by the magnitude of the temperature difference when in the
optimal range.
- Revert "Restarting cgminer from within after ADL has been corrupted only leads
to a crash. Display a warning only and disable fanspeed monitoring."
- api.c fix json already closed
- implement and document API option --api-groups
- Put upper bounds to under 2 hours that work can be rolled into the future for
bitcoind will deem it invalid beyond that.
- define API option --api-groups
- api.c allow unwell devices to be enabled so they can be cured
- miner.php - fix/enable autorefresh for custom pages
- miner.php allow custom summary pages - new 'Mobile' summary
- Work around pools that advertise very low expire= time inappropriately as this
leads to many false positives for stale shares detected.
- Only show ztex board count if any exist.
- There is no need for work to be a union in struct workio_cmd
- fpgautils.c include a debug message for all unknown open errors
- Don't keep rolling work right up to the expire= cut off. Use 2/3 of the time
between the scantime and the expiry as cutoff for reusing work.
- Log a specific error when serial opens fail due to lack of user permissions
- Increase GPU timing resolution to microsecond and add sanity check to ensure
times are positive.
- Opencl code may start executing before the clfinish order is given to it so
get the start timing used for dynamic intensity from before the kernel is
queued.
- fpgautils.c - set BAUD rate according to termio spec
- fpgautils.c - linux ordering back to the correct way
- miner.php remove unneeded '.'s
- miner.php add auto refresh options
- miner.php add 'restart' next to 'quit'
- miner.php make fontname/size configurable with myminer.php
- Make the pools array a dynamically allocated array to allow unlimited pools to
be added.
- Make the devices array a dynamically allocated array of pointers to allow
unlimited devices.
- Dynamic intensity for GPUs should be calculated on a per device basis. Clean
up the code to only calculate it if required as well.
- Use a queueing bool set under control_lock to prevent multiple calls to
queue_request racing.
- Use the work clone flag to determine if we should subtract it from the total
queued variable and provide a subtract queued function to prevent looping over
locked code.
- Don't decrement staged extras count from longpoll work.
- Count longpoll's contribution to the queue.
- Increase queued count before pushing message.
- Test we have enough work queued for pools with and without rolltime
capability.
- As work is sorted by age, we can discard the oldest work at regular intervals
to keep only 1 of the newest work items per mining thread.
- Roll work again after duplicating it to prevent duplicates on return to the
clone function.
- Abstract out work cloning and clone $mining_threads copies whenever a rollable
work item is found and return a clone instead.
- api.c display Pool Av in json
- Take into account average getwork delay as a marker of pool communications
when considering work stale.
- Work out a rolling average getwork delay stored in pool_stats.
- Getwork delay in stats should include retries for each getwork call.
- Walk through the thread list instead of searching for them when disabling
threads for dynamic mode.
- Extend nrolltime to support the expiry= parameter. Do this by turning the
rolltime bool into an integer set to the expiry time. If the pool supports
rolltime but not expiry= then set the expiry time to the standard scantime.
- When disabling fanspeed monitoring on adl failure, remove any twin GPU
association. This could have been leading to hangs on machines with dual GPU
cards when ADL failed.
- modminer: Don't delay 2nd+ FPGAs during work restart
- Disable OpenCL code when not available.
- Fix openwrt crashing on regeneratehash() by making check_solve a noop.
- FPGA - allow device detect override without an open failure
- Fix sign warning.
