2018-03-23target/arm: Honour MDCR_EL2.TDE when routing exceptions due to BKPT/BRKPeter Maydell1-2/+13
The MDCR_EL2.TDE bit allows the exception level targeted by debug exceptions to be set to EL2 for code executing at EL0. We handle this in the arm_debug_target_el() function, but this is only used for hardware breakpoint and watchpoint exceptions, not for the exception generated when the guest executes an AArch32 BKPT or AArch64 BRK instruction. We don't have enough information for a translate-time equivalent of arm_debug_target_el(), so instead make BKPT and BRK call a special purpose helper which can do the routing, rather than the generic exception_with_syndrome helper.

2018-03-23arm/translate-a64: treat DISAS_UPDATE as variant of DISAS_EXITVictor Kamensky1-3/+3
In OE project 4.15 linux kernel boot hang was observed under single cpu aarch64 qemu. Kernel code was in a loop waiting for vtimer arrival, spinning in TC generated blocks, while interrupt was pending unprocessed. This happened because when qemu tried to handle vtimer interrupt target had interrupts disabled, as result flag indicating TCG exit, cpu->icount_decr.u16.high, was cleared but arm_cpu_exec_interrupt function did not call arm_cpu_do_interrupt to process interrupt. Later when target reenabled interrupts, it happened without exit into main loop, so following code that waited for result of interrupt execution run in infinite loop. To solve the problem instructions that operate on CPU sys state (i.e enable/disable interrupt), and marked as DISAS_UPDATE, should be considered as DISAS_EXIT variant, and should be forced to exit back to main loop so qemu will have a chance processing pending CPU state updates, including pending interrupts. This change brings consistency with how DISAS_UPDATE is treated in aarch32 case.
