2018-10-26xen: Use the PCI_DEVICE macroPhilippe Mathieu-Daudé
TYPE_XEN_PT_DEVICE is a subclass of TYPE_PCI_DEVICE, the clean way to access the PCIDevice pointer is using the PCI_DEVICE() macro.

into staging First RISC-V Patch Set for the 3.1 Soft Freeze This pull request contains a handful of patches that have been floating around various trees for a while but haven't made it upstream. These patches all appear quite safe. They're all somewhat independent from each other: * One refactors our IRQ management function to allow multiple interrupts to be raised an once. This patch has no functional difference. * Cleaning up the op_helper/cpu_helper split. This patch has no functional difference. * Updates to various constants to keep them in sync with the latest ISA specification and to remove some non-standard bits that snuck in. * A fix for a memory leak in the PLIC driver. * A fix to our device tree handling to avoid provinging a NULL string. I've given this my standard test: building the port, booting a Fedora root filesytem on the latest Linux tag, and then shutting down that image. Essentially I'm just following the QEMU RISC-V wiki page's instructions. Everything looks fine here. We have a lot more outstanding patches so I'll definately be submitting another PR for the soft freeze. # gpg: Signature made Wed 17 Oct 2018 21:17:52 BST # gpg: using RSA key EF4CA1502CCBAB41 # gpg: Good signature from "Palmer Dabbelt <palmer@dabbelt.com>" # gpg: aka "Palmer Dabbelt <palmer@sifive.com>" # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 00CE 76D1 8349 60DF CE88 6DF8 EF4C A150 2CCB AB41 * remotes/riscv/tags/riscv-for-master-3.1-sf0: RISC-V: Don't add NULL bootargs to device-tree RISC-V: Add missing free for plic_hart_config RISC-V: Update CSR and interrupt definitions RISC-V: Move non-ops from op_helper to cpu_helper RISC-V: Allow setting and clearing multiple irqs Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2018-10-24linux-user/mips: Recognize the R5900 CPU modelFredrik Noring
This kind of ELF for the R5900 relies on an IEEE 754-1985 compliant FPU. The R5900 FPU hardware is noncompliant and it is therefore emulated in software by the Linux kernel. QEMU emulates a compliant FPU accordingly.

2018-10-24target/mips: Define the R5900 CPUFredrik Noring
The primary purpose of this change is to support programs compiled by GCC for the R5900 target and thereby run R5900 Linux distributions, for example Gentoo. GCC in version 7.3, by itself, by inspection of the GCC source code and inspection of the generated machine code, for the R5900 target, only emits two instructions that are specific to the R5900: the three- operand MULT and MULTU. GCC and libc also emit certain MIPS III instructions that are not part of the R5900 ISA. They are normally trapped and emulated by the Linux kernel, and therefore need to be treated accordingly by QEMU. A program compiled by GCC is taken to mean source code compiled by GCC under the restrictions above. One can, with the apparent limitations, with a bit of effort obtain a fully functioning operating system such as R5900 Gentoo. Strictly speaking, programs need not be compiled by GCC to make use of this change. Instructions and other facilities of the R5900 not implemented by this change are intended to signal provisional exceptions. One such example is the FPU that is not compliant with IEEE 754-1985 in system mode. It is therefore provisionally disabled. In user space the FPU is trapped and emulated by IEEE 754-1985 compliant software in the kernel, and this is handled accordingly by QEMU. Another example is the 93 multimedia instructions specific to the R5900 that generate provisional reserved instruction exception signals. One of the benefits of running a Linux distribution under QEMU is that programs can be compiled with a native compiler, where the host and target are the same, as opposed to a cross-compiler, where they are not the same. This is especially important in cases where the target hardware does not have the resources to run a native compiler. Problems with cross-compilation are often related to host and target differences in integer sizes, pointer sizes, endianness, machine code, ABI, etc. Sometimes cross-compilation is not even supported by the build script for a given package. One effective way to avoid those problems is to replace the cross-compiler with a native compiler. This change of compilation methods does not resolve the inherent problems with cross-compilation. The native compiler naturally replaces the cross-compiler, because one typically uses one or the other, and preferably the native compiler when the circumstances admit this. The native compiler is also a good test case for the R5900 QEMU user mode. Additionally, Gentoo is well- known for compiling and installing its packages from sources. This change has been tested with Gentoo compiled for R5900, including native compilation of several packages under QEMU.

2018-10-24target/mips: Make R5900 DMULT[U], DDIV[U], LL[D] and SC[D] user onlyFredrik Noring
The Linux kernel traps certain reserved instruction exceptions to emulate the corresponding instructions. QEMU plays the role of the kernel in user mode, so those traps are emulated by accepting the instructions. This change adds the function check_insn_opc_user_only to signal a reserved instruction exception for flagged CPUs in QEMU system mode. The MIPS III instructions DMULT[U], DDIV[U], LL[D] and SC[D] are not implemented in R5900 hardware. They are trapped and emulated by the Linux kernel and, accordingly, therefore QEMU user only instructions.
