2020-08-21trace: switch position of headers to what Meson requiresPaolo Bonzini
Meson doesn't enjoy the same flexibility we have with Make in choosing the include path. In particular the tracing headers are using $(build_root)/$(<D). In order to keep the include directives unchanged, the simplest solution is to generate headers with patterns like "trace/trace-audio.h" and place forwarding headers in the source tree such that for example "audio/trace.h" includes "trace/trace-audio.h". This patch is too ugly to be applied to the Makefiles now. It's only a way to separate the changes to the tracing header files from the Meson rewrite of the tracing logic.

2020-07-10xen: Use ERRP_GUARD()Vladimir Sementsov-Ogievskiy
If we want to check error after errp-function call, we need to introduce local_err and then propagate it to errp. Instead, use the ERRP_GUARD() macro, benefits are: 1. No need of explicit error_propagate call 2. No need of explicit local_err variable: use errp directly 3. ERRP_GUARD() leaves errp as is if it's not NULL or &error_fatal, this means that we don't break error_abort (we'll abort on error_set, not on error_propagate) If we want to add some info to errp (by error_prepend() or error_append_hint()), we must use the ERRP_GUARD() macro. Otherwise, this info will not be added when errp == &error_fatal (the program will exit prior to the error_append_hint() or error_prepend() call). No such cases are being fixed here.

2020-07-10error: Eliminate error_propagate() with Coccinelle, part 1Markus Armbruster
When all we do with an Error we receive into a local variable is propagating to somewhere else, we can just as well receive it there right away. Convert if (!foo(..., &err)) { ... error_propagate(errp, err); ... return ... } to if (!foo(..., errp)) { ... ... return ... } where nothing else needs @err. Coccinelle script: @rule1 forall@ identifier fun, err, errp, lbl; expression list args, args2; binary operator op; constant c1, c2; symbol false; @@ if ( ( - fun(args, &err, args2) + fun(args, errp, args2) | - !fun(args, &err, args2) + !fun(args, errp, args2) | - fun(args, &err, args2) op c1 + fun(args, errp, args2) op c1 ) ) { ... when != err when != lbl: when strict - error_propagate(errp, err); ... when != err ( return; | return c2; | return false; ) } @rule2 forall@ identifier fun, err, errp, lbl; expression list args, args2; expression var; binary operator op; constant c1, c2; symbol false; @@ - var = fun(args, &err, args2); + var = fun(args, errp, args2); ... when != err if ( ( var | !var | var op c1 ) ) { ... when != err when != lbl: when strict - error_propagate(errp, err); ... when != err ( return; | return c2; | return false; | return var; ) } @depends on rule1 || rule2@ identifier err; @@ - Error *err = NULL; ... when != err Not exactly elegant, I'm afraid. The "when != lbl:" is necessary to avoid transforming if (fun(args, &err)) { goto out } ... out: error_propagate(errp, err); even though other paths to label out still need the error_propagate(). For an actual example, see sclp_realize(). Without the "when strict", Coccinelle transforms vfio_msix_setup(), incorrectly. I don't know what exactly "when strict" does, only that it helps here. The match of return is narrower than what I want, but I can't figure out how to express "return where the operand doesn't use @err". For an example where it's too narrow, see vfio_intx_enable(). Silently fails to convert hw/arm/armsse.c, because Coccinelle gets confused by ARMSSE being used both as typedef and function-like macro there. Converted manually. Line breaks tidied up manually. One nested declaration of @local_err deleted manually. Preexisting unwanted blank line dropped in hw/riscv/sifive_e.c.

2020-05-15qom: Drop parameter @errp of object_property_add() & friendsMarkus Armbruster
The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().

Several objects implemented their own uint property getters and setters, despite them being straightforward (without any checks/validations on the values themselves) and identical across objects. This makes use of an enhanced API for object_property_add_uintXX_ptr() which offers default setters. Some of these setters used to update the value even if the type visit failed (eg. because the value being set overflowed over the given type). The new setter introduces a check for these errors, not updating the value if an error occurred. The error is propagated.

It includes the PowerBus logic interface (PBCQ), IOMMU support, a single PCIe Gen.3 Root Complex, and support for MSI and LSI interrupt sources as found on a POWER8 system using the XICS interrupt controller. The POWER8 processor comes in different flavors: Venice, Murano, Naple, each having a different number of PHBs. To make things simpler, the models provides 3 PHB3 per chip. Some platforms, like the Firestone, can also couple PHBs on the first chip to provide more bandwidth but this is too specific to model in QEMU. XICS requires some adjustment to support the PHB3 MSI. The changes are provided here but they could be decoupled in prereq patches.

It includes the PowerBus logic interface (PBCQ), IOMMU support, a single PCIe Gen.4 Root Complex, and support for MSI and LSI interrupt sources as found on a POWER9 system using the XIVE interrupt controller. POWER9 processor comes with 3 PHB4 PEC (PCI Express Controller) and each PEC can have several PHBs. By default, * PEC0 provides 1 PHB (PHB0) * PEC1 provides 2 PHBs (PHB1 and PHB2) * PEC2 provides 3 PHBs (PHB3, PHB4 and PHB5) Each PEC has a set "global" registers and some "per-stack" (per-PHB) registers. Those are organized in two XSCOM ranges, the "Nest" range and the "PCI" range, each range contains both some "PEC" registers and some "per-stack" registers. No default device layout is provided and PCI devices can be added on any of the available PCIe Root Port (pcie.0 .. 2 of a Power9 chip) with address 0x0 as the firwware (skiboot) only accepts a single device per root port. To run a simple system with a network and a storage adapters, use a command line options such as : -device e1000e,netdev=net0,mac=C0:FF:EE:00:00:02,bus=pcie.0,addr=0x0 -netdev bridge,id=net0,helper=/usr/libexec/qemu-bridge-helper,br=virbr0,id=hostnet0 -device megasas,id=scsi0,bus=pcie.1,addr=0x0 -drive file=$disk,if=none,id=drive-scsi0-0-0-0,format=qcow2,cache=none -device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,bootindex=2 If more are needed, include a bridge.

2020-01-29hw/core/loader: Let load_elf() populate a field with CPU-specific flagsAleksandar Markovic
While loading the executable, some platforms (like AVR) need to detect CPU type that executable is built for - and, with this patch, this is enabled by reading the field 'e_flags' of the ELF header of the executable in question. The change expands functionality of the following functions: - load_elf() - load_elf_as() - load_elf_ram() - load_elf_ram_sym() The argument added to these functions is called 'pflags' and is of type 'uint32_t*' (that matches 'pointer to 'elf_word'', 'elf_word' being the type of the field 'e_flags', in both 32-bit and 64-bit variants of ELF header). Callers are allowed to pass NULL as that argument, and in such case no lookup to the field 'e_flags' will happen, and no information will be returned, of course.

2020-01-22q35: implement 128K SMRAM at default SMBASE addressIgor Mammedov
It's not what real HW does, implementing which would be overkill [**] and would require complex cross stack changes (QEMU+firmware) to make it work. So considering that SMRAM is owned by MCH, for simplicity (ab)use reserved Q35 register, which allows QEMU and firmware easily init and make RAM at SMBASE available only from SMM context. Patch uses commit (2f295167e0 q35/mch: implement extended TSEG sizes) for inspiration and uses reserved register in config space at 0x9c offset [*] to extend q35 pci-host with ability to use 128K at 0x30000 as SMRAM and hide it (like TSEG) from non-SMM context. Usage: 1: write 0xff in the register 2: if the feature is supported, follow up read from the register should return 0x01. At this point RAM at 0x30000 is still available for SMI handler configuration from non-SMM context 3: writing 0x02 in the register, locks SMBASE area, making its contents available only from SMM context. In non-SMM context, reads return 0xff and writes are ignored. Further writes into the register are ignored until the system reset. *) https://www.mail-archive.com/qemu-devel@nongnu.org/msg455991.html **) https://www.mail-archive.com/qemu-devel@nongnu.org/msg646965.html Signed-off-by: Igor Mammedov <imammedo@redhat.com> Message-Id: <1575896942-331151-3-git-send-email-imammedo@redhat.com> Reviewed-by: Michael S.
