2011-06-03	s390x: fix cksm instruction	Alexander Graf	1	-20/+8
	The cksm instruction was implemented incorrectly, rendering UDP and TCP checksum calculation wrong, making an emulated s390x Linux guest break in most networking operations. This patch fixes odd end checksum calculation, takes the input register as input for the checksum and optimizes the overflow pieces by a bit. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-20	s390x: fix memory detection for guests > 64GB	Christian Borntraeger	1	-2/+6
	the s390 memory detection has a 16bit field that specifies the amount of increments. This patch adopts the memory size to always fit into that scheme. This also fixes virtio detection for these guests, since the descriptor page is located after the main memory.

2011-05-20	s390x: Implement opcode helpers	Alexander Graf	1	-2/+2917
	There are some instructions that can't (or shouldn't) be expressed by pure tcg code. For those, we call into externally compiled C functions. This patch implements those C functions. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-20	s390x: helper functions for system emulation	Alexander Graf	1	-0/+6
	When running system emulation, we need to transverse through the MMU and deliver interrupts according to the specification. This patch implements those two pieces and in addition adjusts the CPU initialization code to account for the new fields in CPUState. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-04-20	Remove unused function parameter from cpu_restore_state	Stefan Weil	1	-1/+1
	The previous patch removed the need for parameter puc. Is is now unused, so remove it. Cc: Aurelien Jarno <aurelien@aurel32.net> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Stefan Weil <weil@mail.berlios.de>
2010-03-07	Update to a hopefully more future proof FSF address	Blue Swirl	1	-2/+1

2009-12-05	S/390 CPU fake emulation	Alexander Graf	1	-0/+74
	Because Qemu currently requires a TCG target to exist and there are quite some useful helpers here to lay the groundwork for out KVM target, let's create a stub TCG emulation target for S390X CPUs. This is required to make tcg happy. The emulation target itself won't work though. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
