Code Issues Releases Packages Activity

This tag contains the following changes for kernel 5.7:

Browse source 
- MMU code improvements that includes:
   - Flush MMU TLB cache only once, at the end of mapping/unmapping
     function, instead of flushing after mapping of every page.
   - Add future ASIC support by splitting properties of ASIC capabilities
     regarding mapping of host memory to regular and huge pages.
 
 - Add debugfs interface to write and read 64-bit values from the device's
   memory/registers. Previously the driver provided interface for 32-bit
   values and this will allow the user to debug much more quickly. We saw it
   gives a boost of around 1.5 - 1.7 when reading internal memories.
 
 - Support temperature offset via sysfs as defined in
   https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface
 
 - Display historical maximum of various sensors.
 
 - Print to kernel log when clock throttling occurs to due breach of power
   or thermal envelope. Also prints when clock throttling is finished
   (clock is back to optimal).
 
 - Fix bug when moving from manual to auto power-management mode.
 
 - Print a message ("unsupported device") to kernel log in case a GAUDI device
   is recognized.
 
 - Small bug fixes and minor improvements to code.
