We have obsoleted the device tree, and mainly support ACPI now on Reference/Production HW. Below is the TMFIFO definition in the ACPI DSDT table. // RShim TMFIFO Device(RSH0) { Name(_HID, "MLNXBF01") Name(_UID, Zero) Name(_CCA, 1) Name(_CRS, ResourceTemplate() { Memory32Fixed(ReadWrite, 0x00800a20, 0x00000018) Memory32Fixed(ReadWrite, 0x00800a40, 0x00000018) Interrupt(ResourceConsumer, Edge, ActiveHigh, Exclusive) { BF1_RSH0_TM_HTT_LWM_INT, BF1_RSH0_TM_HTT_HWM_INT, BF1_RSH0_TM_TTH_LWM_INT, BF1_RSH0_TM_TTH_HWM_INT } }) } The full ACPI implementation can be found in the 1.0 release: http://www.mellanox.com/downloads/BlueField/BlueField-1.0.0.10521/BlueField-1.0.0.10521.tar.xz Inside this tarball, we can see the "src/edk2/" directory which has the edk2 patch file including all the ACPI implementation. > > I need to have a separate look at the fifo driver. > > Unfortunately, you have sent these patches during the merge window, > which is the time during which we don't pick up new work.

I'll resend it to make sure not to miss the date.
