From 2de8b91f36f71584c34df899e8c2cc57fbad806f Mon Sep 17 00:00:00 2001 From: Marius Muench Date: Tue, 17 Sep 2019 15:53:59 +0200 Subject: [PATCH] Pretender (#3) * ARM: added a configurable machine * Small fixes * Fixed compilation error * Support for system-wide named semaphores * Added support for message queues * IPC: fixes permission on message queues and semaphores creation * Message queues: non-blocking Conflicts: include/qemu/thread-posix.h * Avatar: Modifications to the IPC interface Extracted from 6e31210a3c13f4b6db7d7db5262cc47278e1f693 * Started the memory forwarder device * Configurable: entry address and endianness * somewhat working remotememoryreadrequests * RemoteMemory! * Experimental removal of ram-resizable flag * Small fixes on the configurable machine * error handling in remote memory * integrated change in qapi * Hotfix: Don't bail out on failed rmr/rmw * Fixed bug regarding entrypoint, removed load_kernel and set_endianness from configurable machine * Cleaned up configurable machine and added MIPS-support * Adjusted RMemory to hold pc * bugfix in configurable machine * Banked registers! * move header files to include/hw/avatar * Refactored avatar mqueueing * starting on interrupt-injection * Unclean hackish commit to be squashed later * WIP: interrupt_exec and avatar_log * added log_item for avatar * minimal changes * nvic-related changes (untested!) * bugfixes * Banked registers! * nvic-write-forward update * let\'s return xpsr and not cpsr * Refactored avatar mqueueing * new logging for interrupts * move header files to include/hw/avatar * minor fixes * ignore/unignore irq returns * not enabling - stuff should be fine * additional interrupt notifications and acks * bugfix * Allow board init for more than armv7m * format strings are hard * Add set_nvic_base to qmp * I meant vector table base, not nvic base * fix compile on 18.04 * Update to comply with qemu-3.1 * cpu-model -> cpu-type * make usage of the new ARM_CPU_TYPE_NAME macro * temporary race condition hotfix: don't emit qapi_resume/stop --- cpus.c | 8 +- hw/avatar/Makefile.objs | 1 + hw/avatar/configurable_machine.c | 20 +- hw/avatar/interrupts.c | 180 + hw/avatar/remote_memory.c | 22 +- hw/intc/armv7m_nvic.c | 4 + include/hw/avatar/interrupts.h | 26 + include/hw/avatar/remote_memory.h | 4 + include/qemu/log.h | 1 + qapi-schema.json | 6445 +++++++++++++++++++++++++++++ qapi/avatar.json | 75 + qapi/qapi-schema.json | 1 + target/arm/gdbstub.c | 9 +- target/arm/helper.c | 2 + util/log.c | 2 + 15 files changed, 6775 insertions(+), 25 deletions(-) create mode 100644 hw/avatar/interrupts.c create mode 100644 include/hw/avatar/interrupts.h create mode 100644 qapi-schema.json create mode 100644 qapi/avatar.json diff --git a/cpus.c b/cpus.c index 63bda152f5..31672b513f 100644 --- a/cpus.c +++ b/cpus.c @@ -2171,7 +2171,7 @@ int vm_stop(RunState state) return 0;
