I am having similar problems using a locally built version of IASL from the 20120420-32 source. I can switch to a locally built version of the IASL compiler from the 20110623-32 source with no other changes and successfully build SeaBIOS. Note that I cannot build with IASL 20110623 binaries (Windows) from ACPICA, so there's something unique about our 20110623 build. ==== (-1): 20120711-32 (Windows using ACPICA binary) =========================== Compiling DSDT Intel ACPI Component Architecture ASL Optimizing Compiler version 20120711-32 [Jul 11 2012] Copyright (c) 2000 - 2012 Intel Corporation Error 4092 - Could not open file "ssdt-proc.dsl.i" (No such file or directory) Makefile:223: recipe for target `src/ssdt-proc.hex' failed make[2]: *** [src/ssdt-proc.hex] Error 1 make[2]: *** Waiting for unfinished jobs....

[BUG] BSOD on Win2003 Server when 64bit PCI resource is present
by Alexey Korolev 26 Jul '12

26 Jul '12

HI, Current version of Seabios is causing blue screen on Windows2003 when 64bit PCI resource is present and occupies high memory. BSOD Error code is: 0x000000A5 (0x02, 0xFFFFfADF6A446880, 0x1, 0xFFFFFADFAA34690) The issue is localized, it is related to presence of 64bit resource in _CRS method. If we disable a 64bit region from _CRS the Win2003 load normally but this doesn't allow Windows to use 64bit resources. At the moment I have no idea how to fix this. Please help! P/S Yet another issue is related to debug messages. If I add any DBUG call in acpi-dst it will cause BSOD on win2003 (win2008 works fine)

ISA device and shared memory
by Albin Kauffmann 26 Jul '12

26 Jul '12

Hello, I'm trying to add the support for an old com90c65 ISA card (a network device using the old ARCnet protocol and handled by the com90xx Linux module). This device is using both IO ports and IO memory. The I/O ports are working and the code is largely inspired from the ne2k_isa support. However, I have not find the right way to register the I/O memory. I've tried the following code : static const MemoryRegionOps com90c65_mmio_ops = { .read = com90c65_mmio_read, .write = com90c65_mmio_write, .endianness = DEVICE_NATIVE_ENDIAN, }; [...] memory_region_init_io(&s->mmio, &com90c65_mmio_ops, s, "com90c65-mmio", size); memory_region_add_subregion(isa_address_space(dev), isa_mem_base + isa->mmiobase, &s->mmio); Depending on mmiobase, I get : - mmiobase == 0xd0000 : no error message but debuging QEMU shows me that my read/write functions are not called. - mmiobase == 0xd0800 : the following error : qemu-system-i386: [...]/qemu-1.1.0/exec.c:2371: register_subpage: Assertion `existing->mr->subpage || existing->mr == &io_mem_unassigned' failed Because the ISA and PCI memory areas seem to overlap and as the ISA bus is accessed via a PCI to ISA bridge, they might be something else to initialize but I can't find what and browsing the QEMU code didn't help me. However, I have managed to make it work by using a call to memory_region_add_subregion_overlap() with a priority bigger than the PCI one (priority >= 2) but it only works with mmiobase == 0xd0000. As it might also be a seabios configuration problem, I have added the seabios mailing list in the recipients. In attachement, you'll find the output of info mtree, info qtree and the logs of seabios. Any help will be really appreciated, Thanks :) -- Albin Kauffmann

SeaBIOS, FW_CFG_NUMA, and FW_CFG_MAX_CPUS
by Eduardo Habkost 25 Jul '12

25 Jul '12

Hi, While working at the CPU index vs APIC ID changes, I stumbled upon another not-very-well-defined interface between SeaBIOS and QEMU, and I would like to clarify the semantics and constraints of some FW_CFG entries. First, the facts/assumptions: - There's no concept of "CPU index" or "CPU identifier" that SeaBIOS and QEMU agree upon, except for the APIC ID. All SeaBIOS can really see are the CPU APIC IDs, on boot or on CPU hotplug. - The APIC ID is already a perfectly good CPU identifier, that is present on bare metal hardware too. - Adding a new kind of "CPU identifier" in addition to the APIC ID would just make things more complex. - The only problem with APIC IDs is that they may not be contiguous. That said, I would like to clarify the meaning of: - FW_CFG_MAX_CPUS What are the basic semantics and expectations about FW_CFG_MAX_CPUS? Considering that the APIC IDs may not be contiguous, is it supposed to be: a) the maximum number of CPUs that will be ever online, doesn't matter their APIC IDs, or b) a value so that every CPU has APIC ID < MAX_CPUS. A practical example: suppose we have a machine with 18 CPUs with the following APIC IDs: 0x00, 0x01, 0x02, 0x04, 0x05, 0x06, 0x08, 0x09, 0x0a, 0x10, 0x11, 0x12, 0x14, 0x15, 0x16, 0x18, 0x19, 0x1a. (That's the expected result for a machine with 2 sockets, 3 cores per socket, 3 threads per core.) In that case, should FW_CFG_MAX_CPUS be: a) 18, or b) 27 (0x1b)? If it should be 18, it will require additional work on SeaBIOS to make: - CPU hotplug work - SRAT/MADT/SSDT tables be built with Processor ID != APIC ID - SRAT/MADT/SSDT tables be kept stable if the system is hibernated and resumed after a CPU is hot-plugged. (Probably in that case I would suggest introducing a FW_CFG_MAX_APIC_ID entry, so that SeaBIOS can still build the ACPI tables more easily). - FW_CFG_NUMA The first problem with FW_CFG_NUMA is that it depends on FW_CFG_MAX_CPUS (so it inherits the same questions above). The second is that FW_CFG_NUMA is a CPU-based table, but there's nothing SeaBIOS can use to know what CPUs FW_CFG_NUMA is refering to, except for the APIC IDs. So, should FW_CFG_NUMA be indexed by APIC IDs? - My proposal: My proposal is to try to keep things simple, and just use the following rule: - Never have a CPU with APIC ID > FW_CFG_MAX_CPUS. This way: - The SeaBIOS ACPI code can be kept simple. - The current CPU hotplug interface can work as-is (up to 256 CPUs), based on APIC IDs. - The current FW_CFG_NUMA interface can work as-is, indexed by APIC IDs. - The ACPI tables can be easily kept stable between hibernate and resume, after CPU hotplug. This is the direction I am trying to go, and I am sending this just to make sure nobody is against it, and to not surprise anybody when I send a QEMU patch to make FW_CFG_MAX_CPUS be based on APIC IDs. My second proposal would be to introduce a FW_CFG_MAX_APIC_ID entry, so the SeaBIOS ACPI code can be kept simple. My third proposal would be to introduce a FW_CFG CPU Index => APIC ID table, but I really wouldn't like to introduce a new type of CPU identifier to be used between QEMU and SeaBIOS, when the APIC ID is a perfectly good unique CPU identifier that already exists in bare metal hardware. -- Eduardo
