2019-12-18Deal with a case where DMI read returns busy.Tim Newsome2-19/+46
This was exposed by the latest change, which modifies the number of scans enough that this problem is now exposed by the testsuite. This particular failure could happen in more cases, but I don't have the time to address everything right now. In the real world they'll be very rare. It only shows up in the test because it intentionally resets the learned delays while a memory access is happening.. Change-Id: Ia865eb76ed630c3d836131a065ec2dad0657c9b4

Combine SMP group registers into one list for gdb
2019-10-11Combine SMP group registers into one list for gdbTim Newsome1-2/+74
This makes behavior when you've configured an SMP group of heterogeneous targets a bit less weird. (You still shouldn't be doing that, since gdb and who knows what else assumes that the targets in an SMP group are homogeneous.) Specifically, if you have a HiFive Unleashed board (where the first core is fairly basic and the other 4 or more full-featured) this lets you connect to all 5, and still have access to the FPU etc. on the higher numbered cores.

Using batch transactions avoids an unnecessary dmi read after every dmi write, resulting in a significant performance improvement.

2019-09-24helper/command: clear errno before calling parserChristopher Head1-0/+1
The C standard says that errno is set to ERANGE if an out-of-range value is returned by strtol, strtoul, et. al., but it does not say that errno is cleared if the function is successful (and, indeed, it is not on glibc). This means that, if errno is ERANGE before strtol is called, and if the value to be converted is exactly the maximum (or, for a signed conversion, the minimum) legal value, COMMAND_PARSE_NUMBER will erroneously indicate that the value is out of range.
