2022-12-03hwthread: Restore current_threadid in hwthread_update_threadsKoudai Iwahori1-0/+10
When OpenOCD receives a step-execution command from GDB and the target is configured as rtos=hwthread, OpenOCD reconstructs the thread-info. However, OpenOCD does not restore the thread id which is currently selected by GDB. Due to this issue, OpenOCD sends the information of wrong thread to GDB after the step execution. This commit fixes the above issue by adding a code to save/restore the thread id selected by GDB.

When OpenOCD receives 'g' packet (read general registers) from GDB and target is configured as rtos=hwthread, hwthread_get_thread_reg_list is called. However, it does not check if the register valid or not. Due to this issue, OpenOCD returns invalid register values to GDB. This commit adds a validity check to hwthread_get_thread_reg_list. If the register is not valid, it tries to read the register from the target.

However, if you are using the hard-coded RCW or your boot source is otherwise corrupt, then the general purpose processors will never be released from hold-off. This will cause GDB to become confused if it tries to attach, since they will appear to be running arm32 processors. To deal with this, we can release the CPUs manually with the BRRL register. This register cannot be written to from the axi target, so we need to do it from the service processor target. This involves halting the service processor, modifying the register, and then resuming it again. We try and determine what state the service processor was in to avoid resuming it if it was already halted. The reset vector for the general purpose processors is determined by the boot logation pointer registers in the device configuration unit. Normally these are set using pre-boot initialization commands, but if they are not set then they default to 0. This will cause the CPU to almost immediately hit an illegal instruction. This is fine because we will almost certainly want to attach to the processor and load a program anyway. I considered adding this as an event handler for either gdb-attach or reset-init. However, this command shouldn't be necessary most of the time, and so I don't think we should run it automatically.

This only covers the "primary" JTAG header J55, and not the PCIe header (J91). The only oddity is that the LS1088A and CPLD are muxed by adding/removing a jumper from J48. Unfortunately, it doesn't look like OpenOCD supports this CPLD beyond determining the irlen, so it's not very useful. Those who are interested in experimenting can define CWTAP to access the CPLD, but the default is to access the CPU.

The targets armv7a in file cortex_a.c inherit the register list from file armv4_5.c thus, depending on the core status, some register get marked as not existing. For HW threads other than current target, the registers in the list are not checked for existence and are all forwarded to GDB that in turns complains for too many data: Remote 'g' packet reply is too long (expected 68 bytes, got 104 bytes) Check all the attributes of the registers and pass to GDB only the valid registers. To test it, use a SMP cortex-a target (2 cores are enough) and add -rtos hwthread to all the cores.
