target/s390x: start moving TCG-only code to tcg/

2021-07-07T12:01:56+00:00

move everything related to translate, as well as HELPER code in tcg/ mmu_helper.c stays put for now, as it contains both TCG and KVM code. After the reshuffling, update MAINTAINERS accordingly.

s390x/tcg: Define vector instruction formats

2019-03-11T08:31:01+00:00

These are the new instruction formats related to vector instructions as up to the z14 (a.k.a. latest PoP). As v2 appeares (like x2 in VRX) with d2/b2 in VRV, we have to assign it a higher field number to avoid collisions. Properly take care of the MSB (to be able to address 32 registers) for each vector register field stored in the RXB field (Bit 36 - 30 for all vector instructions). As we have 32 bit vector registers and the "v" fields are only 4 bit in size, the 5th bit is stored in the RXB. We use a new type to indicate that the MSB has to be fetched from the RXB.

Move target-* CPU file into a target/ folder

2016-12-20T20:52:12+00:00

We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
