Currently if user enables HVC_DCC config option in Linux, it invokes access
to debug data transfer registers (ie DBGDTRTX_EL0 on arm64, DBGDTRTXINT on
arm32). As these registers are not emulated, Xen injects an undefined
exception to the VM and Linux (running as VM) crashes.
DBGOSLSR is emulated in the same way as its AArch64 variant (ie OSLSR_EL1).
This is to ensure that DBGOSLSR.OSLK is 0, thus MDSCR_EL1.TXfull is treated
as UNK/SBZP.
Thus only MDCCSR_EL0 can be emulated (which is DBGDSCRINT on arm32).
DBGDSCRINT can be accessed at EL0 as DBGDSCREXT is emulated as
Hi,

for the previous discussion on this issue.
Also, the linux earlycon hvc driver has been fixed.
See
There can be situations when the registers cannot be emulated to their full
functionality. This can be due to the complexity involved. In such cases, one
can emulate those registers as RAZ/WI. We call them as partial emulation.
A suitable example of this (as seen in subsequent patches) is
