Public bug reported: SRU Justification:
[Impact] Support the I2C lock mechanism, otherwise there could be unexpected behavior when the i2c driver is accessed by several entities like the linux driver, ATF driver and UEFI driver. [Fix] * Support lock and unlock * replace ioremap_nocache with ioremap [Test Case] * Make sure the i2c-mlxbf.c driver is loaded and /dev/i2c-1 is created * check that ipmitool from the BF->BMC and from the BMC->BF work (this only applies on boards with a BMC of course) [Regression Potential] Any of the test cases above could be impacted due to these changes. ** Affects: linux-bluefield (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-bluefield in Ubuntu. https://bugs.launchpad.net/bugs/1981105 Title: i2c-mlxbf.c: support lock mechanism Status in linux-bluefield package in Ubuntu: New Bug description: SRU Justification: [Impact] Support the I2C lock mechanism, otherwise there could be unexpected behavior when the i2c driver is accessed by several entities like the linux driver, ATF driver and UEFI driver.
