Note: Some less frequently needed CSR registers (e.g. hpm and pmp registers) are commented out on purpose. Instructions to add them back are described in remote_gdb.hh comments. This is to avoid spamming the remote GDB log when using `info reg all`. Changes: 1. Added GDB XML files to the ext/ directory (mostly from QEMU) 2. Modified RiscvGdbRegCache - struct r: added CSR registers - getRegs, setRegs: reading / setting CSR registers 3. Modified RemoteGDB - availableFeatures: indicate support for XML registers - getXferFeaturesRead: return XML blobs Change-Id: Ica03b63edb3f0c9b6a7789228b995891dbfb26b2 Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/38955 Reviewed-by: Jason Lowe-Power <power.jg@gmail.com> Maintainer: Jason Lowe-Power <power.jg@gmail.com> Tested-by: kokoro <noreply+kokoro@google.com>
