SME support for AArch64 gdb/gdbserver on Linux
|

Message
Luis Machado
May 19, 2023, 10:24 a.m. UTC
The following series enables SME 1 (Scalable Matrix Extension) support for
AArch64 gdb and gdbserver.
SME expands on SVE by having a variable-sized matrix (ZA) of dimensions
SVL x SVL bytes.
The first few patches and some intermediate ones refactor the code and fix
issues prior to enabling SME support, and thus could go in independently.
I've kept them in the series as they are closely/logically related.
