Hi, I have modified a driver source for eMMC controller (added a new device in the table) and I want to debug an issue (HS400 mode not working) with the device. I compiled and loaded the sdhci_acpi module, now I'm new to FreeBSD and device driver development, so I was wondering what are the ways I can debug this issue, any resources, and utilities that would make it easier to debug this problem. I see there is a debug flag (hw.sdhci_acpi.debug), which I enabled using sysctl, but I'm not sure how to utilize it. Any help is appreciated :) Thanks Shreyank
