[...] That's what I thought, too... but Segher said otherwise in January, and Tarl said the internal cell size (that I'm trying to change here) were different from the guest-visible 32-bit cell size. Through the use of prog_arg_t the CIF is supposed to remain 32-bit.
If I recall correctly what I said, the device-tree property cell size is _always_ 32-bit, regardless of what the internal cell size is.
On SPARCs, we have three things we refer to as cell size: - The internal cell size (defined by /n), 64 bits - The device tree cell size, defined by 1275 to always be 32 bits - The cell size presented to FCode version 2 drivers (plug-in cards), which is emulated to be 32 bits.
