2019-09-30s390: do not call memory_region_allocate_system_memory() multiple timesIgor Mammedov2-27/+14
s390 was trying to solve limited KVM memslot size issue by abusing memory_region_allocate_system_memory(), which breaks API contract where the function might be called only once. Beside an invalid use of API, the approach also introduced migration issue, since RAM chunks for each KVM_SLOT_MAX_BYTES are transferred in migration stream as separate RAMBlocks. After discussion [1], it was agreed to break migration from older QEMU for guest with RAM >8Tb (as it was relatively new (since 2.12) and considered to be not actually used downstream). Migration should keep working for guests with less than 8TB and for more than 8TB with QEMU 4.2 and newer binary. In case user tries to migrate more than 8TB guest, between incompatible QEMU versions, migration should fail gracefully due to non-exiting RAMBlock ID or RAMBlock size mismatch. Taking in account above and that now KVM code is able to split too big MemorySection into several memslots, partially revert commit (bb223055b s390-ccw-virtio: allow for systems larger that 7.999TB) and use kvm_set_max_memslot_size() to set KVMSlot size to KVM_SLOT_MAX_BYTES. 1) [PATCH RFC v2 4/4] s390: do not call memory_region_allocate_system_memory() multiple times Signed-off-by: Igor Mammedov <imammedo@redhat.com> Message-Id: <20190924144751.24149-5-imammedo@redhat.com> Acked-by: Peter Xu <peterx@redhat.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com>
2019-09-30kvm: split too big memory section on several memslotsIgor Mammedov2-44/+81
Max memslot size supported by kvm on s390 is 8Tb, move logic of splitting RAM in chunks upto 8T to KVM code. This way it will hide KVM specific restrictions in KVM code and won't affect board level design decisions. Which would allow us to avoid misusing memory_region_allocate_system_memory() API and eventually use a single hostmem backend for guest RAM.

On IBM Z, KVM in the kernel is only implemented for 64-bit mode, and with regards to TCG, we also only support 64-bit host CPUs (see the check at the beginning of tcg/s390/tcg-target.inc.c), so we should remove s390 (without "x", i.e. the old 31-bit mode CPUs) from the list of supported CPUs.

2019-09-27hw/arm/boot.c: Set NSACR.{CP11,CP10} for NS kernel bootsPeter Maydell1-0/+2
If we're booting a Linux kernel directly into Non-Secure state on a CPU which has Secure state, then make sure we set the NSACR CP11 and CP10 bits, so that Non-Secure is allowed to access the FPU. Otherwise an AArch32 kernel will UNDEF as soon as it tries to use the FPU. It used to not matter that we didn't do this until commit fc1120a7f5f2d4b6, where we implemented actually honouring these NSACR bits. The problem only exists for CPUs where EL3 is AArch32; the equivalent AArch64 trap bits are in CPTR_EL3 and are "0 to not trap, 1 to trap", so the reset value of the register permits NS access, unlike NSACR.

For AArch64 CPUs with a CBAR register, we have two views for it: - in AArch64 state, the CBAR_EL1 register (S3_1_C15_C3_0), returns the full 64 bits CBAR value - in AArch32 state, the CBAR register (cp15, opc1=1, CRn=15, CRm=3, opc2=0) returns a 32 bits view such that: CBAR = CBAR_EL1[31:18] 0..0 CBAR_EL1[43:32] This commit fixes the current implementation where: - CBAR_EL1 was returning the 32 bits view instead of the full 64 bits value, - CBAR was returning a truncated 32 bits version of the full 64 bits one, instead of the 32 bits view - CBAR was declared as cp15, opc1=4, CRn=15, CRm=0, opc2=0, which is the CBAR register found in the ARMv7 Cortex-Ax CPUs, but not in ARMv8 CPUs.

2019-09-26tests/docker: remove debian-powerpc-user-crossAlex Bennée2-30/+0
Despite our attempts in 4d26c7fef4 to keep this going it still gets in the way of "make docker-test-build" completing because of course we can't build a modern QEMU with the image. Let's put the thing out of its misery and remove it. People who really care about building on powerpc can still use the binfmt_misc support to manually build an image (or just run the build from pre this commit).

2019-09-26docker: move tests from python2 to python3John Snow7-7/+7
As part of the push to drop python2 support, replace any explicit python2 dependencies with python3 versions. For centos, python2 still exists as an implicit dependency, but by adding python3 we will be able to build even if the configure script begins to require python 3.5+. Tested with centos7, fedora, ubuntu, ubuntu1804, and debian 9 (amd64). Tested under a custom configure script that requires Python 3.5+. the travis dockerfile is also moved to using python3, which was tested by running `make docker-test-build@travis`, which I hope is sufficient.

This adds two new tests that re-use the memory test to check basic record replay functionality is still working. We have to define our own runners rather than using the default pattern as we want to change the test name but re-use the memory binary. We declare the test binaries as PHONY as they don't really exist.

This is a generic floating point multiply and accumulate test for single precision floating point values. I've split of the common float functions into a helper library so additional tests can use the same common code.
