2023-10-04virtio: don't zero out memory region cache for indirect descriptorsIlya Maximets2-8/+28
Lots of virtio functions that are on a hot path in data transmission are initializing indirect descriptor cache at the point of stack allocation. It's a 112 byte structure that is getting zeroed out on each call adding unnecessary overhead. It's going to be correctly initialized later via special init function. The only reason to actually initialize right away is the ability to safely destruct it. Replacing a designated initializer with a function to only initialize what is necessary. Removal of the unnecessary stack initializations improves throughput of virtio-net devices in terms of 64B packets per second by 6-14 % depending on the case. Tested with a proposed af-xdp network backend and a dpdk testpmd application in the guest, but should be beneficial for other virtio devices as well.

2023-10-04virtio: add vhost-user-base and a generic vhost-user-deviceAlex Bennée4-0/+443
In theory we shouldn't need to repeat so much boilerplate to support vhost-user backends. This provides a generic vhost-user-base QOM object and a derived vhost-user-device for which the user needs to provide the few bits of information that aren't currently provided by the vhost-user protocol. This should provide a baseline implementation from which the other vhost-user stub can specialise.

In order to make vhost-vdpa.c a target-agnostic source unit, we need to remove the TARGET_PAGE_SIZE / TARGET_PAGE_MASK / TARGET_PAGE_ALIGN uses. TARGET_PAGE_SIZE will be replaced by the runtime qemu_target_page_size(). The other ones will be deduced from TARGET_PAGE_SIZE. Since the 3 macros are used in 3 related functions (sharing the same call tree), we'll refactor them to only depend on TARGET_PAGE_MASK. Having the following call tree: vhost_vdpa_listener_region_del() -> vhost_vdpa_listener_skipped_section() -> vhost_vdpa_section_end() The first step is to propagate TARGET_PAGE_MASK to vhost_vdpa_listener_skipped_section().

current code sets PCI_SEC_LATENCY_TIMER to RW, but for pcie to pcie bridges it must be RO 0 according to pci express spec which says: This register does not apply to PCI Express. It must be read-only and hardwired to 00h. For PCI Express to PCI/PCI-X Bridges, refer to the [PCIe-to-PCI-PCI-X-Bridge] for requirements for this register. also, fix typo in comment where it's made writeable - this typo is likely what prevented us noticing we violate this requirement in the 1st place.

The for-loop does not make much sense here - it is always left after the first iteration, so we can also check for nb_nics == 1 instead which is way easier to understand. Also, the checks for nd->model are superfluous since the code in mips_jazz_init_net() calls qemu_check_nic_model() that already takes care of this (i.e. initializing nd->model if it has not been set yet, and checking whether it is the "help" option or the supported NIC model).

2023-09-25meson.build: Make keyutils independent from keyringThomas Huth3-2/+9
Commit 0db0fbb5cf ("Add conditional dependency for libkeyutils") tried to provide a possibility for the user to disable keyutils if not required by makeing it depend on the keyring feature. This looked reasonable at a first glance (the unit test in tests/unit/ needs both), but the condition in meson.build fails if the feature is meant to be detected automatically, and there is also another spot in backends/meson.build where keyutils is used independently from keyring. So let's remove the dependency on keyring again and introduce a proper meson build option instead.

The precedence of "HCRX bits acts as 0 if SCR_EL3.HXEn is 0" versus "bit acts as 1 if EL2 disabled" is not clear from the register definition text, but it is clear in the CheckMOPSEnabled() pseudocode(), so we follow that.

2023-09-21target/arm: Don't skip MTE checks for LDRT/STRT at EL0Peter Maydell1-0/+9
The LDRT/STRT "unprivileged load/store" instructions behave like normal ones if executed at EL0. We handle this correctly for the load/store semantics, but get the MTE checking wrong. We always look at s->mte_active[is_unpriv] to see whether we should be doing MTE checks, but in hflags.c when we set the TB flags that will be used to fill the mte_active[] array we only set the MTE0_ACTIVE bit if UNPRIV is true (i.e. we are not at EL0). This means that a LDRT at EL0 will see s->mte_active[1] as 0, and will not do MTE checks even when MTE is enabled. To avoid the translate-time code having to do an explicit check on s->unpriv to see if it is OK to index into the mte_active[] array, duplicate MTE_ACTIVE into MTE0_ACTIVE when UNPRIV is false. (This isn't a very serious bug because generally nobody executes LDRT/STRT at EL0, because they have no use there.)
