This tag contains the following changes for kernel 5.7:
- 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. -----BEGIN PGP SIGNATURE----- iQFJBAABCgA0FiEE7TEboABC71LctBLFZR1NuKta54AFAl55zpQWHG9kZWQuZ2Fi YmF5QGdtYWlsLmNvbQAKCRBlHU24q1rngOuHB/iBZhX6XY5uRMW4BIOxfXC+x3by r0lugR7pvlJ+w+SrM3IjwAxlF6T9QDfiZviS5MqnRhSupTFzmekGbq6KZEnLmuyQ nsnzLBW2auzf8kjAIrCB7ddl6GfakJS4elyZMKEhQkWmQsJJ6vv+TvACOVvHzb1J o4lXxRqeEruzA/OBXxaTjC9MLQa/tRyT6LQoSg4L+bHlx/JZO5T1eFQWcMACoWV1 75ZV6o7vaVRpFx3CTMF5S+MQCoZbroYNwNz/Xaqc8ezpCFB2LzheYpKUXpuf9Y47 lnDAoHKnozOoZDVDzgdc5hgGeNOnRISSAkmAnI0rKg+JZKOw+v02Zw7nciA= =FUs3 -----END PGP SIGNATURE-----
