2023-07-14kconfig: Add PCIe devices to s390x machinesCédric Le Goater
It is useful to extend the number of available PCIe devices to KVM guests for passthrough scenarios and also to expose these models to a different (big endian) architecture. Introduce a new config PCIE_DEVICES to select models, Intel Ethernet adapters and one USB controller. These devices all support MSI-X which is a requirement on s390x as legacy INTx are not supported.

2023-05-30arm/Kconfig: Keep Kconfig default entries in default.mak as documentationFabiano Rosas
When we moved the arm default CONFIGs into Kconfig and removed them from default.mak, we made it harder to identify which CONFIGs are selected by default in case users want to disable them. Bring back the default entries into default.mak, but keep them commented out. This way users can keep their workflows of editing default.mak to remove build options without needing to search through Kconfig.

2023-05-02arm/Kconfig: Do not build TCG-only boards on a KVM-only buildFabiano Rosas
Move all the CONFIG_FOO=y from default.mak into "default y if TCG" statements in Kconfig. That way they won't be selected when CONFIG_TCG=n. I'm leaving CONFIG_ARM_VIRT in default.mak because it allows us to keep the two default.mak files not empty and keep aarch64-default.mak including arm-default.mak. That way we don't surprise anyone that's used to altering these files. With this change we can start building with --disable-tcg.

2023-05-02arm/Kconfig: Always select SEMIHOSTING when TCG is presentFabiano Rosas
We are about to enable the build without TCG, so CONFIG_SEMIHOSTING and CONFIG_ARM_COMPATIBLE_SEMIHOSTING cannot be unconditionally set in default.mak anymore. So reflect the change in a Kconfig. Instead of using semihosting/Kconfig, use a target-specific file, so that the change doesn't affect other architectures which might implement semihosting in a way compatible with KVM. The selection from ARM_v7M needs to be removed to avoid a cycle during parsing.

Both TCG and KVM emulate ckc, cputm, last_break and prefix, and it's quite useful to have them during debugging. Right now they are grouped together with KVM-only pp, pfault_token, pfault_select and pfault_compare in s390-virt.xml, and are not available when debugging TCG-emulated code.

2021-11-02target/arm: Advertise MVE to gdb when presentPeter Maydell
Cortex-M CPUs with MVE should advertise this fact to gdb, using the org.gnu.gdb.arm.m-profile-mve XML feature, which defines the VPR register. Presence of this feature also tells gdb to create pseudo-registers Q0..Q7, so we do not need to tell gdb about them separately. Note that unless you have a very recent GDB that includes this fix: http://patches-tcwg.linaro.org/patch/58133/ gdb will mis-print the individual fields of the VPR register as zero (but showing the whole thing as hex, eg with "print /x $vpr" will give the correct value).

2021-09-30target/arm: Don't put FPEXC and FPSID in org.gnu.gdb.arm.vfp XMLPeter Maydell
Currently we send VFP XML which includes D0..D15 or D0..D31, plus FPSID, FPSCR and FPEXC. The upstream GDB tolerates this, but its definition of this XML feature does not include FPSID or FPEXC. In particular, for M-profile cores there are no FPSID or FPEXC registers, so advertising those is wrong. Move FPSID and FPEXC into their own bit of XML which we only send for A and R profile cores. This brings our definition of the XML org.gnu.gdb.arm.vfp feature into line with GDB's own (at least for non-Neon cores...) and means we don't claim to have FPSID and FPEXC on M-profile. (It seems unlikely to me that any gdbstub users really care about being able to look at FPEXC and FPSID; but we've supplied them to gdb for a decade and it's not hard to keep doing so.)

The aarch64-linux QEMU usermode binaries can never run 32-bit code, so they do not need to include the GDB XML for it. (arm_cpu_register_gdb_regs_for_features() will not use these XML files if the CPU has ARM_FEATURE_AARCH64, so we will not advertise to gdb that we have them.)

2021-09-04hw/acpi: refactor acpi hp modules so that targets can just use what they needAni Sinha
Currently various acpi hotplug modules like cpu hotplug, memory hotplug, pci hotplug, nvdimm hotplug are all pulled in when CONFIG_ACPI_X86 is turned on. This brings in support for whole lot of subsystems that some targets like mips does not need. They are added just to satisfy symbol dependencies. This is ugly and should be avoided. Targets should be able to pull in just what they need and no more. For example, mips only needs support for PIIX4 and does not need acpi pci hotplug support or cpu hotplug support or memory hotplug support etc. This change is an effort to clean this up. In this change, new config variables are added for various acpi hotplug subsystems. Targets like mips can only enable PIIX4 support and not the rest of all the other modules which were being previously pulled in as a part of CONFIG_ACPI_X86. Function stubs make sure that symbols which piix4 needs but are not required by mips (for example, symbols specific to pci hotplug etc) are available to satisfy the dependencies. Currently, this change only addresses issues with mips malta targets. In future we might be able to clean up other targets which are similarly pulling in lot of unnecessary hotplug modules by enabling ACPI_X86. This change should also address issues such as the following: https://gitlab.com/qemu-project/qemu/-/issues/221 https://gitlab.com/qemu-project/qemu/-/issues/193 Signed-off-by: Ani Sinha <ani@anisinha.ca> Message-Id: <20210812071409.492299-1-ani@anisinha.ca> Reviewed-by: Michael S.
