Subject: [PATCH  v16 28/99] target/arm: split cpregs from tcg/helper.c
Date: Fri,  4 Jun 2021 16:52:01 +0100	[thread overview]
Message-ID: <20210604155312.15902-29-alex.bennee@linaro.org> (raw)
In-Reply-To: <20210604155312.15902-1-alex.bennee@linaro.org>

From: Claudio Fontana <cfontana@suse.de>

give them their own common module cpregs.c, and an interface cpregs.h.
Extract the raw cpustate list to its own module.
This is more or less needed for KVM too.

For the tcg-specific registers, stuff them into tcg/cpregs.c

As a result, the monster that is tcg/helper.c is a bit less scary,
and a lot of stuff is removed from cpu.h too, relegated to cpregs.h.

+ * migrated but may have their state set by syncing of register state from KVM.

+ * support raw access for state saving/loading; it will not be used for either
+ * migration or KVM state synchronization. (Typically this is for "registers"
+ * which are actually used as instructions for cache maintenance and so on.)
+ * IO indicates that this register does I/O and therefore its accesses
+ * need to be marked with gen_io_start() and also end the TB. In particular,
+ * registers which implement clocks or timers require this.
+ * RAISES_EXC is for when the read or write hook might raise an exception;
+ * the generated code will synchronize the CPU state before calling the hook
+ * so that it is safe for the hook to call raise_exception().
+ * NEWEL is for writes to registers that might change the exception
+ * level - typically on older ARM chips. For those cases we need to
+ * re-read the new el when recomputing the translation flags.
