2023-02-06migration: Split save_live_pending() into state_pending_*Juan Quintela
We split the function into to: - state_pending_estimate: We estimate the remaining state size without stopping the machine. - state pending_exact: We calculate the exact amount of remaining state. The only "device" that implements different functions for _estimate() and _exact() is ram. Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com>

This is much better as c_w_mixed, because it is clear if the caller is a coroutine or not, and provides the advantage of automating the code creation.

2022-12-15hw/arm/virt: Add properties to disable high memory regionsGavin Shan
The 3 high memory regions are usually enabled by default, but they may be not used. For example, VIRT_HIGH_GIC_REDIST2 isn't needed by GICv2. This leads to waste in the PA space. Add properties ("highmem-redists", "highmem-ecam", "highmem-mmio") to allow users selectively disable them if needed. After that, the high memory region for GICv3 or GICv4 redistributor can be disabled by user, the number of maximal supported CPUs needs to be calculated based on 'vms->highmem_redists'. The follow-up error message is also improved to indicate if the high memory region for GICv3 and GICv4 has been enabled or not.

2022-12-15hw/arm/virt: Add 'compact-highmem' propertyGavin Shan
After the improvement to high memory region address assignment is applied, the memory layout can be changed, introducing possible migration breakage. For example, VIRT_HIGH_PCIE_MMIO memory region is disabled or enabled when the optimization is applied or not, with the following configuration. The configuration is only achievable by modifying the source code until more properties are added to allow users selectively disable those high memory regions. pa_bits = 40; vms->highmem_redists = false; vms->highmem_ecam = false; vms->highmem_mmio = true; # qemu-system-aarch64 -accel kvm -cpu host \ -machine virt-7.2,compact-highmem={on, off} \ -m 4G,maxmem=511G -monitor stdio Region compact-highmem=off compact-highmem=on ---------------------------------------------------------------- MEM [1GB 512GB] [1GB 512GB] HIGH_GIC_REDISTS2 [512GB 512GB+64MB] [disabled] HIGH_PCIE_ECAM [512GB+256MB 512GB+512MB] [disabled] HIGH_PCIE_MMIO [disabled] [512GB 1TB] In order to keep backwords compatibility, we need to disable the optimization on machine, which is virt-7.1 or ealier than it. It means the optimization is enabled by default from virt-7.2. Besides, 'compact-highmem' property is added so that the optimization can be explicitly enabled or disabled on all machine types by users.

2022-12-13qapi: Start to elide redundant has_FOO in generated CMarkus Armbruster
In QAPI, absent optional members are distinct from any present value. We thus represent an optional schema member FOO as two C members: a FOO with the member's type, and a bool has_FOO. Likewise for function arguments. However, has_FOO is actually redundant for a pointer-valued FOO, which can be null only when has_FOO is false, i.e. has_FOO == !!FOO. Except for arrays, where we a null FOO can also be a present empty array. The redundant has_FOO are a nuisance to work with. Improve the generator to elide them. Uses of has_FOO need to be replaced as follows. Tests of has_FOO become the equivalent comparison of FOO with null. For brevity, this is commonly done by implicit conversion to bool. Assignments to has_FOO get dropped. Likewise for arguments to has_FOO parameters. Beware: code may violate the invariant has_FOO == !!FOO before the transformation, and get away with it. The above transformation can then break things. Two cases: * Absent: if code ignores FOO entirely when !has_FOO (except for freeing it if necessary), even non-null / uninitialized FOO works. Such code is known to exist. * Present: if code ignores FOO entirely when has_FOO, even null FOO works. Such code should not exist. In both cases, replacing tests of has_FOO by FOO reverts their sense. We have to fix the value of FOO then. To facilitate review of the necessary updates to handwritten code, add means to opt out of this change, and opt out for all QAPI schema modules where the change requires updates to handwritten code. The next few commits will remove these opt-outs in reviewable chunks, then drop the means to opt out. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Daniel P.
