2021-04-30hw/pci-host/gpex: Don't fault for unmapped parts of MMIO and PIO windowsPeter Maydell
Currently the gpex PCI controller implements no special behaviour for guest accesses to areas of the PIO and MMIO where it has not mapped any PCI devices, which means that for Arm you end up with a CPU exception due to a data abort. Most host OSes expect "like an x86 PC" behaviour, where bad accesses like this return -1 for reads and ignore writes. In the interests of not being surprising, make host CPU accesses to these windows behave as -1/discard where there's no mapped PCI device. The old behaviour generally didn't cause any problems, because almost always the guest OS will map the PCI devices and then only access where it has mapped them. One corner case where you will see this kind of access is if Linux attempts to probe legacy ISA devices via a PIO window access. So far the only case where we've seen this has been via the syzkaller fuzzer.

2021-01-17acpi/gpex: Inform os to keep firmware resource mapJiahui Cen
There may be some differences in pci resource assignment between guest os and firmware. Eg. A Bridge with Bus [d2] -+-[0000:d2]---01.0-[d3]----01.0 where [d2:01.00] is a pcie-pci-bridge with BAR0 (mem, 64-bit, non-pref) [size=256] [d3:01.00] is a PCI Device with BAR0 (mem, 64-bit, pref) [size=128K] BAR4 (mem, 64-bit, pref) [size=64M] In EDK2, the Resource Map would be: PciBus: Resource Map for Bridge [D2|01|00] Type = PMem64; Base = 0x8004000000; Length = 0x4100000; Alignment = 0x3FFFFFF Base = 0x8004000000; Length = 0x4000000; Alignment = 0x3FFFFFF; Owner = PCI [D3|01|00:20] Base = 0x8008000000; Length = 0x20000; Alignment = 0x1FFFF; Owner = PCI [D3|01|00:10] Type = Mem64; Base = 0x8008100000; Length = 0x100; Alignment = 0xFFF It would use 0x4100000 to calculate the root bus's PMem64 resource window. While in Linux, kernel will use 0x1FFFFFF as the alignment to calculate the PMem64 size, which would be 0x6000000. So kernel would try to allocate 0x6000000 from the PMem64 resource window, but since the window size is 0x4100000 as assigned by EDK2, the allocation would fail. The diffences could result in resource assignment failure. Using _DSM #5 method to inform guest os not to ignore the PCI configuration that firmware has done at boot time could handle the differences.

2020-10-28sabre: increase number of PCI bus IRQs from 32 to 64Mark Cave-Ayland
The rework of the sabre IRQs in commit 6864fa3897 "sun4u: update PCI topology to include simba PCI bridges" changed the IRQ routing so that both PCI and legacy OBIO IRQs are routed through the sabre PCI host bridge to the CPU. Unfortunately this commit failed to increase the number of PCI bus IRQs accordingly meaning that access to the legacy IRQs OBIO (irqnum >= 0x20) would overflow the PCI bus IRQ array causing strange failures running qemu-system-sparc64 in NetBSD.

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.
