commit ea96bc62 doesn't match the patch submitted by Laszlo to qemu-devel. We reuse pc_q35_2_4_machine_options() inside pc_q35_2_3_machine_options(), so we need to undo the no_floppy change in pc_q35_2_3_machine_options(). (This discrepancy was due to a bad merge.) This restores the previous behavior where all the 2.3 and older machines had no_floppy=0.

We now finally have TCG support for the basic set of instructions necessary to run the s390-ccw machine. That means in any aspect possible that machine type is now superior to the legacy s390-virtio machine. Switch over to the ccw machine as default. That way people don't get a halfway broken machine with the s390x target.

This patch adds support for PER Breaking-Event-Address register. Like real hardware, it save the current PSW address when the PSW address is changed by an instruction. We have to take care of optimizations QEMU does, a branch to the next instruction is still a branch. This register is copied to low core memory when a program exception happens.

For the instruction-fetch nullification event, we just reuse the existing instruction-fetch code and trigger the exception immediately in that case. There is no need to save the CPU state in the TCG code as it has been saved by the previous instruction before calling the per_check_exception helper.

For the PER storage-alteration event we can use the QEMU watchpoint infrastructure. When PER is enabled or PER control register changed we enable the corresponding watchpoints. When a watchpoint arises we can save the event. Unfortunately the current code does not provide the address space used to trigger the watchpoint. For now we assume it comes from the default ASC.

The tb_check_watchpoint function currently assumes that all memory access is done either directly through the TCG code or through an helper which knows its return address. This is obviously wrong as the helpers use cpu_ldxx/stxx_data functions to access the memory. Instead of aborting in that case, don't try to retranslate the code, but assume that the CPU state (and especially the program counter) has been saved before calling the helper. Then invalidate the TB based on this address. Signed-off-by: NAurelien Jarno <aurelien@aurel32.net> Signed-off-by: NAlexander Graf <agraf@suse.de>

For the PER instruction-fetch, we can't use the QEMU breakpoint infrastructure as it triggers for a single address and not a full address range, and as it actually stop before the instruction and not before. We therefore call an helper with the just fetched instruction address, which check if the address is within the PER address range. If it is the case, an event is recorded and will be signaled through an exception. Note that we implement here the PER-3 behaviour, that is an invalid opcode is not considered as an instruction fetch. Without PER-3 this behavious is undefined.

For the PER successful-branching event support, we can't rely on any QEMU infrastucture. We therefore call an helper in all places where a branch can be taken. We have to pay attention to the branch to next case, as it's still a taken branch. We don't need to care about the cases using goto_tb, as we have disabled them in the previous patch.

This patch add basic support to generate PER exceptions. It adds two fields to the cpu structure to record for the PER address and PER code & ATMID values. When an exception is triggered and a PER event is pending, the two PER values are copied to the lowcore area. At the end of an instruction, an helper is checking for a possible pending PER event and triggers an exception in that case. For that to work with branches, we need to disable TB chaining when PER is activated. Fortunately it's already in the TB flags. Finally in case of a SERVICE CALL exception, we need to trigger the PER exception immediately after.

mvc_fast_memmove is bypassing the softmmu functions, getting the physical source and destination addresses using the mmu_translate function and accessing the corresponding physical memory. This prevents watchpoints to work correctly. Instead use the tlb_vaddr_to_host function to get the host addresses corresponding to the guest source and destination addresses through the softmmu code and fallback to the byte level code in case the corresponding address are not in the QEMU TLB or being examined through a watchpoint. As a bonus it works even for area crossing pages by splitting the are into chunks contained in a single page, bringing some performances improvements. We can therefore remove the 8-byte loads/stores method, as it is now quite unlikely to be used. At the same time change the name of the function to fast_memmove as it's not specific to mvc and use the same argument order as the C memmove function.
