-Subject: [PATCH] arm/translate-a64: treat DISAS_UPDATE as variant of
- DISAS_EXIT
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit

-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.
