2022-11-22target/arm: Use signed quantity to represent VMSAv8-64 translation levelArd Biesheuvel
The LPA2 extension implements 52-bit virtual addressing for 4k and 16k translation granules, and for the former, this means an additional level of translation is needed. This means we start counting at -1 instead of 0 when doing a walk, and so 'level' is now a signed quantity, and should be typed as such. So turn it from uint32_t into int32_t. This avoids a level of -1 getting misinterpreted as being >= 3, and terminating a page table walk prematurely with a bogus output address.

2022-11-22target/arm: Don't do two-stage lookup if stage 2 is disabledPeter Maydell
In get_phys_addr_with_struct(), we call get_phys_addr_twostage() if the CPU supports EL2. However, we don't check here that stage 2 is actually enabled. Instead we only check that inside get_phys_addr_twostage() to skip stage 2 translation. This means that even if stage 2 is disabled we still tell the stage 1 lookup to do its page table walks via stage 2. This works by luck for normal CPU accesses, but it breaks for debug accesses, which are used by the disassembler and also by semihosting file reads and writes, because the debug case takes a different code path inside S1_ptw_translate(). This means that setups that use semihosting for file loads are broken (a regression since 7.1, introduced in recent ptw refactoring), and that sometimes disassembly in debug logs reports "unable to read memory" rather than showing the guest insns. Fix the bug by hoisting the "is stage 2 enabled?" check up to get_phys_addr_with_struct(), so that we handle S2 disabled the same way we do the "no EL2" case, with a simple single stage lookup.

2022-11-22acpi/tests/avocado/bits: keep the work directory when BITS_DEBUG is set in envAni Sinha
Debugging bits issue often involves running the QEMU command line manually outside of the avocado environment with the generated ISO. Hence, its inconvenient if the iso gets cleaned up after the test has finished. This change makes sure that the work directory is kept after the test finishes if the test is run with BITS_DEBUG=1 in the environment so that the iso is available for use with the QEMU command line.

2022-11-22acpi: x86: move RPQx field back to _SB scopeIgor Mammedov
Commit 47a373faa6b2 (acpi: pc/q35: drop ad-hoc PCI-ISA bridge AML routines and let bus ennumeration generate AML) moved ISA bridge AML generation to respective devices and was using aml_alias() to provide PRQx fields in _SB. scope. However, it turned out that SeaBIOS was not able to process Alias opcode when parsing DSDT, resulting in lack of keyboard during boot (SeaBIOS console, grub, FreeDOS). While fix for SeaBIOS is posted https://mail.coreboot.org/hyperkitty/list/seabios@seabios.org/thread/RGPL7HESH5U5JRLEO6FP77CZVHZK5J65/ fixed SeaBIOS might not make into QEMU-7.2 in time. Hence this workaround that puts PRQx back into _SB scope and gets rid of aliases in ISA bridge description, so DSDT will be parsable by broken SeaBIOS. That brings back hardcoded references to ISA bridge PCI0.S08.P40C/PCI0.SF8.PIRQ where middle part now is auto generated based on slot it's plugged in, but it should be fine as bridge initialization also hardcodes PCI address of the bridge so it can't ever move. Once QEMU tree has fixed SeaBIOS blob, we should be able to drop this part and revert back to alias based approach Reported-by: Volker Rümelin <vr_qemu@t-online.de> Signed-off-by: Igor Mammedov <imammedo@redhat.com> Message-Id: <20221121153613.3972225-3-imammedo@redhat.com> Reviewed-by: Michael S.

2022-11-22vhost: mask VIRTIO_F_RING_RESET for vhost and vhost-user devicesStefano Garzarella
Commit 69e1c14aa2 ("virtio: core: vq reset feature negotation support") enabled VIRTIO_F_RING_RESET by default for all virtio devices. This feature is not currently emulated by QEMU, so for vhost and vhost-user devices we need to make sure it is supported by the offloaded device emulation (in-kernel or in another process). To do this we need to add VIRTIO_F_RING_RESET to the features bitmap passed to vhost_get_features(). This way it will be masked if the device does not support it. This issue was initially discovered with vhost-vsock and vhost-user-vsock, and then also tested with vhost-user-rng which confirmed the same issue. They fail when sending features through VHOST_SET_FEATURES ioctl or VHOST_USER_SET_FEATURES message, since VIRTIO_F_RING_RESET is negotiated by the guest (Linux >= v6.0), but not supported by the device.

2022-11-22tests/avocado: introduce alpine virt test for CIAlex Bennée
The boot_linux tests download and run a full cloud image boot and start a full distro. While the ability to test the full boot chain is worthwhile it is perhaps a little too heavy weight and causes issues in CI. Fix this by introducing a new alpine linux ISO boot in machine_aarch64_virt. This boots a fully loaded -cpu max with all the bells and whistles in 31s on my machine. A full debug build takes around 180s on my machine so we set a more generous timeout to cover that. We don't add a test for lesser GIC versions although there is some coverage for that already in the boot_xen.py tests. If we want to introduce more comprehensive testing we can do it with a custom kernel and initrd rather than a full distro boot.

The Aspeed SDK images are based on OpenBMC which starts a lot of services. The output noise on the console can break from time to time the test waiting for the logging prompt. Change the U-Boot bootargs variable to add "quiet" to the kernel command line and reduce the output volume. This also drops the test on the CPU id which was nice to have but not essential.

2022-11-21rtl8139: honor large send MSS valueStefan Hajnoczi
The Large-Send Task Offload Tx Descriptor (9.2.1 Transmit) has a Large-Send MSS value where the driver specifies the MSS. See the datasheet here: http://realtek.info/pdf/rtl8139cp.pdf The code ignores this value and uses a hardcoded MSS of 1500 bytes instead. When the MTU is less than 1500 bytes the hardcoded value results in IP fragmentation and poor performance. Use the Large-Send MSS value to correctly size Large-Send packets. Jason Wang <jasowang@redhat.com> noticed that the Large-Send MSS value mask was incorrect so it is adjusted to match the datasheet and Linux 8139cp driver. This issue was discussed in the past here: https://lore.kernel.org/all/20161114162505.GD26664@stefanha-x1.localdomain/ Reported-by: Russell King - ARM Linux <linux@armlinux.org.uk> Reported-by: Tobias Fiebig <tobias+git@fiebig.nl> Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1312 Acked-by: Jason Wang <jasowang@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Message-Id: <20221117165554.1773409-4-stefanha@redhat.com>
2022-11-21rtl8139: keep Tx command mode 0 and 1 separateStefan Hajnoczi
There are two Tx Descriptor formats called mode 0 and mode 1. The mode is determined by the Large Send bit. CP_TX_IPCS (bit 18) is defined in mode 1 but the code checks the bit unconditionally. In mode 0 bit 18 is part of the Large Send MSS value. Explicitly check the Large Send bit to distinguish Tx command modes. This avoids bugs where modes are confused. Note that I didn't find any actual bugs aside from needlessly computing the IP checksum when the Large Send bit is enabled.

2022-11-21rtl8139: avoid clobbering tx descriptor bitsStefan Hajnoczi
The device turns the Tx Descriptor into a Tx Status descriptor after fully reading the descriptor. This involves clearing Tx Own (bit 31) to indicate that the driver has ownership of the descriptor again as well as several other bits. The code keeps the first dword of the Tx Descriptor in the txdw0 local variable. txdw0 is reused to build the first word of the Tx Status descriptor. Later on the code uses txdw0 again, incorrectly assuming that it still contains the first dword of the Tx Descriptor. The tx offloading code misbehaves because it sees bogus bits in txdw0. Use a separate local variable for Tx Status and preserve Tx Descriptor in txdw0.

With LPA2, the effective output address size is at most 48 bits when TCR.DS == 0. This case is currently unhandled in the page table walker, where we happily assume LVA/64k granule when outputsize > 48 and param.ds == 0, resulting in the wrong conversion to be used from a page table descriptor to a physical address. if (outputsize > 48) { if (param.ds) { descaddr |= extract64(descriptor, 8, 2) << 50; } else { descaddr |= extract64(descriptor, 12, 4) << 48; } So cap the outputsize to 48 when TCR.DS is cleared, as per the architecture.

Trying to run U-Boot for Cubieboard (Allwinner A10) fails because it cannot access SD card. The problem is that FIFO register in current allwinner-sdhost implementation is at the address corresponding to Allwinner H3, but not A10. Linux kernel is not affected since Linux driver uses DMA access and does not use FIFO register for reading/writing. This patch adds new class parameter `is_sun4i` and based on that parameter uses register at offset 0x100 either as FIFO register (if sun4i) or as threshold register (if not sun4i; in this case register at 0x200 is FIFO register). Tested with U-Boot and Linux kernel image built for Cubieboard and OrangePi PC.

Multifd thread model does not work for compression, explicitly disable it. Note that previuosly even we can enable both of them, nothing will go wrong, because the compression code has higher priority so multifd feature will just be ignored. Now we'll fail even earlier at config time so the user should be aware of the consequence better. Note that there can be a slight chance of breaking existing users, but let's assume they're not majority and not serious users, or they should have found that multifd is not working already. With that, we can safely drop the check in ram_save_target_page() for using multifd, because when multifd=on then compression=off, then the removed check on save_page_use_compression() will also always return false too.

In qemu_file_shutdown(), there's a possible race if with current order of operation. There're two major things to do: (1) Do real shutdown() (e.g. shutdown() syscall on socket) (2) Update qemufile's last_error We must do (2) before (1) otherwise there can be a race condition like: page receiver other thread ------------- ------------ qemu_get_buffer() do shutdown() returns 0 (buffer all zero) (meanwhile we didn't check this retcode) try to detect IO error last_error==NULL, IO okay install ALL-ZERO page set last_error --> guest crash! To fix this, we can also check retval of qemu_get_buffer(), but not all APIs can be properly checked and ultimately we still need to go back to qemu_file_get_error(). E.g. qemu_get_byte() doesn't return error. Maybe some day a rework of qemufile API is really needed, but for now keep using qemu_file_get_error() and fix it by not allowing that race condition to happen. Here shutdown() is indeed special because the last_error was emulated. For real -EIO errors it'll always be set when e.g. sendmsg() error triggers so we won't miss those ones, only shutdown() is a bit tricky here. Cc: Daniel P.
