This patch series reflects a slew of changes that fell out of team meetings with mesa/kmd members over the last week. We remove the "risky" option and the --print command since it's more annoying than helpful. We add the ability to specify the VMID in hex with --vram which is handy with the last patch since you can specify which VM hub to use in hex easier than in decimal. The third patch includes various small cleanups found by static analysis and code review. The last patch includes two new features which were written at the same time and were a bit tricky to separate (more effort than worth). First, we add the ability to halt waves when reading them which should help reading consistent data. Next we add the ability to decode multimedia IBs from the UVD/VCN rings. Next we fix using the 'mmMC_VM_FB_LOCATION' register which was traditionally zero on VI (and below) but now has non-zero values which broke VM decoding. Tested on Carrizo/Polaris/Raven. Finally, the last patch adds the ability to specify a 'verbose' option which prints out VM decoding information handy for debugging both umr and the kmd.
