2022-11-29Revert "src/arch/x86: Use core apic id to get cpu_index()"Arthur Heymans
This reverts commit 095c931cf12924da9011b47aa64f4a6f11d89f13. Previously cpu_info() was implemented with a struct on top of an aligned stack. As FSP changed the stack value cpu_info() could not be used in FSP context (which PPI is). Now cpu_info() uses GDT segments, which FSP does not touch so it can be used. This also exports cpu_infos from cpu.c as it's a convenient way to get the struct device * for a certain index. TESTED on aldrvp: FSP-S works and is able to run code on APs.

2022-11-13drivers/generic/ioapic: Drop poor implementationKyösti Mälkki
This disables MP table generation for the affected boards since interrupt routing entries would now be completely missing. The mechanism itself is flawed and redundant. The mapping of integrated PCI devices' INTx pins to IOAPIC pins is dependent of configuration registers and needs not appear in the devicetree.cb files at all. The write_smp_table implementation would skip writing any entry delivering to destination IOAPIC ID 0. This does not follow MP table specification. There were duplicate calls to register_new_ioapic_gsi0(), with another present under southbridge LPC device.

gcc12+ will require riscv architecture selection to come not only with featurei suffixd charactersa, it also comes with feature_ful suffix_ed words_mith. Much creative, very appreciate. To accommodate for this madness, enable the already existing (but off by default) support for that in our gcc11 build, support using by detecting the compiler's behavior in xcompile and pass that knowledge along to our build system.

2022-08-26x86: Zero SMBIOS region before writing tablesJonathon Hall
Clear the SMBIOS region before writing SMBIOS tables. On librem_mini and librem_mini_v2, CBMEM allocations are offset by 4K for reboots relative to the cold boot. This means the unused SMBIOS region could contain the first 4K of the ACPI tables from the last boot (including the signature), which prevents Linux from booting. The CBMEM 4K offset appears to be due to FSP allocating memory differently between cold boot and reboot, this appears to be normal and causes the CBMEM base address to change. It is not clear why Linux examines an ACPI signature found in this region, but boot logs over serial confirm that it sees the corrupt table. The table is supposed to be found just below 1M, and kernel source appears to look in this region, but it is definitely finding the corrupt table in CBMEM. Normal cold boot: [ 0.008615] ACPI: RSDP 0x00000000000F6190 000024 (v02 COREv4) [ 0.008619] ACPI: XSDT 0x0000000099B480E0 00005C (v01 COREv4 COREBOOT 00000000 CORE 20220331) [ 0.008624] ACPI: FACP 0x0000000099B4A2A0 000114 (v06 COREv4 COREBOOT 00000000 CORE 20220331) [ 0.008634] ACPI: DSDT 0x0000000099B48280 00201F (v02 COREv4 COREBOOT 20110725 INTL 20220331) ...

2022-07-14commonlib: Substitude macro "__unused" in compiler.hBill XIE
Since there are many identifiers whose name contain "__unused" in headers of musl libc, introducing a macro which expands "__unused" to the source of a util may have disastrous effect during its compiling under a musl-based platform. However, it is hard to detect musl at build time as musl is notorious for having explicitly been refusing to add a macro like "__MUSL__" to announce its own presence. Using __always_unused and __maybe_unused for everything may be a good idea. This is how it works in the Linux kernel, so that would at least make us match some other standard rather than doing our own thing (especially since the other compiler.h shorthand macros are also inspired by Linux).

2022-05-12Makefile.inc: Generate master header and pointer as C structsArthur Heymans
The makefiles don't like cbfs file names with spaces in them so update the file name with '_' instead of spaces. To keep the master header at the top of cbfs, add a placeholder. This removes the need to handle the cbfs master header in cbfstool. This functionality will be dropped in a later CL. On x86 reserve some space in the linker script to add the pointer. On non-x86 generate a pointer inside a C struct file. As a bonus this would actually fix the master header pointer mechanism on Intel/APL as only the bootblock inside IFWI gets memory mapped. TESTED on thinkpad X201: SeaBIOS correctly finds the cbfs master header.
