src/sys/dev/ichsmb, branch stable/13 FreeBSD source tree ichsmb: fix block read operation 2024-02-17T19:22:08+00:00 Andriy Gapon avg@FreeBSD.org 2022-09-13T21:26:35+00:00 faa59e9ab402b12f3c3d3386175a178e45308b22 First of all and unlike I2C, it's not the master that dictates how many bytes to read in block read operation. It's the device that informs the master how many bytes it's sending back. Thus, for ichsmb_bread() the count parameter is purely an output parameter. The code has been changed to reflect that. The sanity checking of the response length is now done once it (the first byte of the response) is received. While here, handling of ICH_HST_STA_FAILED status bit has been added. Plus some code style improvements and some new code comments in the vicinity of the changed code. (cherry picked from commit cbf7c81b608bb9311e50df9481447dc843083a0e)
