2023-07-26qapi: Reformat recent doc comments to conform to current conventionsMarkus Armbruster9-57/+55
Since commit a937b6aa739 (qapi: Reformat doc comments to conform to current conventions), a number of comments not conforming to the current formatting conventions were added. No problem, just sweep the entire documentation once more. To check the generated documentation does not change, I compared the generated HTML before and after this commit with "wdiff -3". Finds no differences. Comparing with diff is not useful, as the reflown paragraphs are visible there.

trace-event-set-state's explanation of how events are selected is under "Features". Doesn't belong there. Simply delete it, as it feels redundant with documentation of member @name. trace-event-get-state's explanation is under "Returns". Tolerable, but similarly redundant. Delete it, too.

2023-07-25target/sparc: Handle FPRS correctly on big-endian hostsPeter Maydell4-5/+6
In CPUSparcState we define the fprs field as uint64_t. However we then refer to it in translate.c via a TCGv_i32 which we set up with tcg_global_mem_new_ptr(). This means that on a big-endian host when the guest does something to writo te the FPRS register this value ends up in the wrong half of the uint64_t, and the QEMU C code that refers to env->fprs sees the wrong value. The effect of this is that guest code that enables the FPU crashes with spurious FPU Disabled exceptions. In particular, this is why tests/avocado/machine_sparc64_sun4u.py:Sun4uMachine.test_sparc64_sun4u times out on an s390 host. There are multiple ways we could fix this; since there are actually only three bits in the FPRS register and the code in translate.c would be a bit painful to convert to dealing with a TCGv_i64, change the type of the CPU state struct field to match what translate.c is expecting. (None of the other fields referenced by the r32[] array in sparc_tcg_init() have the wrong type.)

2023-07-25target/mips: Avoid shift by negative number in page_table_walk_refill()Peter Maydell1-15/+17
Coverity points out that in page_table_walk_refill() we can shift by a negative number, which is undefined behaviour (CID 1452918, 1452920, 1452922). We already catch the negative directory_shift and leaf_shift as being a "bail out early" case, but not until we've already used them to calculated some offset values. The shifts can be negative only if ptew > 1, so make the bail-out-early check look directly at that, and only calculate the shift amounts and the offsets based on them after we have done that check. This allows us to simplify the expressions used to calculate the shift amounts, use an unsigned type, and avoids the undefined behaviour.

Since commit c0a55a0c9da2 "hw/sd/sdhci: Support big endian SD host controller interfaces" sdhci_common_realize() forces all SD card controllers to use either sdhci_mmio_le_ops or sdhci_mmio_be_ops, depending on the "endianness" property. However, there are device models which use different MMIO ops: TYPE_IMX_USDHC uses usdhc_mmio_ops and TYPE_S3C_SDHCI uses sdhci_s3c_mmio_ops. Forcing sdhci_mmio_le_ops breaks SD card handling on the "sabrelite" board, for example. Fix this by defaulting the io_ops to little endian and switch to big endian in sdhci_common_realize() only if there is a matchig big endian variant available.

2023-07-25target/arm: Special case M-profile in debug_helper.c codePeter Maydell1-6/+12
A lot of the code called from helper_exception_bkpt_insn() is written assuming A-profile, but we will also call this helper on M-profile CPUs when they execute a BKPT insn. This used to work by accident, but recent changes mean that we will hit an assert when some of this code calls down into lower level functions that end up calling arm_security_space_below_el3(), arm_el_is_aa64(), and other functions that now explicitly assert that the guest CPU is not M-profile. Handle M-profile directly to avoid the assertions: * in arm_debug_target_el(), M-profile debug exceptions always go to EL1 * in arm_debug_exception_fsr(), M-profile always uses the short format FSR (compare commit d7fe699be54b2, though in this case the code in arm_v7m_cpu_do_interrupt() does not need to look at the FSR value at all) Cc: qemu-stable@nongnu.org Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1775 Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20230721143239.1753066-1-peter.maydell@linaro.org

The POSIX definition of the 'read' utility requires that you specify the variable name to set; omitting the name and having it default to 'REPLY' is a bashism. If your system sh is dash, then it will print an error message during build: qemu/pc-bios/s390-ccw/../../scripts/git-submodule.sh: 106: read: arg count Specify the variable name explicitly.

2023-07-25hw/arm/smmu: Handle big-endian hosts correctlyPeter Maydell2-10/+32
The implementation of the SMMUv3 has multiple places where it reads a data structure from the guest and directly operates on it without doing a guest-to-host endianness conversion. Since all SMMU data structures are little-endian, this means that the SMMU doesn't work on a big-endian host. In particular, this causes the Avocado test machine_aarch64_virt.py:Aarch64VirtMachine.test_alpine_virt_tcg_gic_max to fail on an s390x host. Add appropriate byte-swapping on reads and writes of guest in-memory data structures so that the device works correctly on big-endian hosts. As part of this we constrain queue_read() to operate only on Cmd structs and queue_write() on Evt structs, because in practice these are the only data structures the two functions are used with, and we need to know what the data structure is to be able to byte-swap its parts correctly.

The virtio-gpu test is known to be flaky - that's why we also did not enable the test_s390x_fedora in the gitlab CI. However, a flaky test can also be annoying when testing locally, so let's rather skip this subtest by default and start running the test_s390x_fedora test in the gitlab CI again (since the other things that are tested here are quite valuable).

2023-07-24target/loongarch: Fix the CSRRD CPUID instruction on big endian hostsThomas Huth4-7/+12
The test in tests/avocado/machine_loongarch.py is currently failing on big endian hosts like s390x. By comparing the traces between running the QEMU_EFI.fd bios on a s390x and on a x86 host, it's quickly obvious that the CSRRD instruction for the CPUID is behaving differently. And indeed: The code currently does a long read (i.e. 64 bit) from the address that points to the CPUState->cpu_index field (with tcg_gen_ld_tl() in the trans_csrrd() function). But this cpu_index field is only an "int" (i.e. 32 bit). While this dirty pointer magic works on little endian hosts, it of course fails on big endian hosts. Fix it by using a proper helper function instead. Message-Id: <20230720175307.854460-1-thuth@redhat.com> Reviewed-by: Song Gao <gaosong@loongson.cn> Signed-off-by: Thomas Huth <thuth@redhat.com>

The tests from tests/avocado/migration.py do not work at all on s390x - the bios shuts down immediately when it cannot find a boot disk, so there is nothing left to migrate here. For doing a proper migration test, we would need a proper payload, but we already do such tests in the migration *qtest*, so it is unnecessary to redo such a test here, thus let's simply remove this test.
