2023-10-06arch/x86/cpu_common: Add cpu_get_c_substate_supportPatrick Rudolph
Add a function to get the number of substates supported by an Intel CPU C-state. Test: Can read out the supported C-state substates.

2023-10-02x86/include/arch/cpuid.h: Fix inline assemblyPatrick Rudolph
In the cpuid helper functions eax is always written to by the cpuid instruction, so add it to the output clobbered list. This prevents GCC from generating code with undefined behaviour when the function is inlined. Test: Verified that the generated assembly is sane and runtime tests showed no "strange" behaviour when calling cpuid functions.

2023-09-14x86: Add .data section support for pre-memory stagesJeremy Compostella
x86 pre-memory stages do not support the `.data` section and as a result developers are required to include runtime initialization code instead of relying on C global variable definition. To illustrate the impact of this lack of `.data` section support, here are two limitations I personally ran into: 1. The inclusion of libgfxinit in romstage for Raptor Lake has required some changes in libgfxinit to ensure data is initialized at runtime. In addition, we had to manually map some `.data` symbols in the `_bss` region. 2. CBFS cache is currently not supported in pre-memory stages and enabling it would require to add an initialization function and find a generic spot to call it. Other platforms do not have that limitation. Hence, resolving it would help to align code and reduce compilation based restriction (cf. the use of `ENV_HAS_DATA_SECTION` compilation flag in various places of coreboot code). We identified three cases to consider: 1. eXecute-In-Place pre-memory stages - code is in SPINOR - data is also stored in SPINOR but must be linked in Cache-As-RAM and copied there at runtime 2. `bootblock` stage is a bit different as it uses Cache-As-Ram but the memory mapping and its entry code different 3. pre-memory stages loaded in and executed from Cache-As-RAM (cf. `CONFIG_NO_XIP_EARLY_STAGES`). eXecute-In-Place pre-memory stages (#1) require the creation of a new ELF segment as the code segment Virtual Memory Address and Load Memory Address are identical but the data needs to be linked in cache-As-RAM (VMA) but to be stored right after the code (LMA). Here is the output `readelf --segments` on a `romstage.debug` ELF binary. Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align LOAD 0x000080 0x02000000 0x02000000 0x21960 0x21960 R E 0x20 LOAD 0x0219e0 0xfefb1640 0x02021960 0x00018 0x00018 RW 0x4 Section to Segment mapping: Segment Sections... 00 .text 01 .data Segment 0 `VirtAddr` and `PhysAddr` are at the same address while they are totally different for the Segment 1 holding the `.data` section. Since we need the data section `VirtAddr` to be in the Cache-As-Ram and its `PhysAddr` right after the `.text` section, the use of a new segment is mandatory. `bootblock` (#2) also uses this new segment to store the data right after the code and load it to Cache-As-RAM at runtime. However, the code involved is different. Not eXecute-In-Place pre-memory stages (#3) do not really need any special work other than enabling a data section as the code and data VMA / LMA translation vector is the same. TEST=#1 and #2 verified on rex and qemu 32 and 64 bits: - The `bootblock.debug`, `romstage.debug` and `verstage.debug` all have data stored at the end of the `.text` section and code to copy the data content to the Cache-As-RAM. - The CBFS stages included in the final image has not improperly relocated any of the `.data` section symbol. - Test purposes global data symbols we added in bootblock, romstage and verstage are properly accessible at runtime #3: for "Intel Apollolake DDR3 RVP1" board, we verified that the generated romstage ELF includes a .data section similarly to a regular memory enabled stage.

According to ACPI Release 6.5 systems supporting PIC (i8259) interrupt mechanism need to report IRQ vector for the SCI_INT field. In PIC mode only IRQ0..15 are allowed hardware vectors. This change should cover section 5.2.9 to not pass SCI_INT larger than IRQ15. Section 5.2.15.5 needs follow-up work. Care should be taken that ioapic_get_sci_pin() is called after platform code has potentially changed the routing from the default.

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.

2021-10-05arch/x86,cpu/x86: Introduce new method for accessing cpu_infoRaul E Rangel
There is currently a fundamental flaw in the current cpu_info() implementation. It assumes that current stack is CONFIG_STACK_SIZE aligned. This assumption breaks down when performing SMM relocation. The first step in performing SMM relocation is changing the SMBASE. This is accomplished by installing the smmstub at 0x00038000, which is the default SMM entry point. The stub is configured to set up a new stack with the size of 1 KiB (CONFIG_SMM_STUB_STACK_SIZE), and an entry point of smm_do_relocation located in RAMSTAGE RAM. This means that when smm_do_relocation is executed, it is running in SMM with a different sized stack. When cpu_info() gets called it will be using CONFIG_STACK_SIZE to calculate the location of the cpu_info struct. This results in reading random memory. Since cpu_info() has to run in multiple environments, we can't use a compile time constant to locate the cpu_info struct. This CL introduces a new way of locating cpu_info. It uses a per-cpu segment descriptor that points to a per-cpu segment that is allocated on the stack. By using a segment descriptor to point to the per-cpu data, we no longer need to calculate the location of the cpu_info struct. This has the following advantages: * Stacks no longer need to be CONFIG_STACK_SIZE aligned. * Accessing an unconfigured segment will result in an exception. This ensures no one can call cpu_info() from an unsupported environment. * Segment selectors are cleared when entering SMM and restored when leaving SMM. * There is a 1:1 mapping between cpu and cpu_info. When using COOP_MULTITASKING, a new cpu_info is currently allocated at the top of each thread's stack. This no longer needs to happen. This CL guards most of the code with CONFIG(CPU_INFO_V2). I did this so reviewers can feel more comfortable knowing most of the CL is a no-op. I would eventually like to remove most of the guards though. This CL does not touch the LEGACY_SMP_INIT code path. I don't have any way of testing it. The %gs segment was chosen over the %fs segment because it's what the linux kernel uses for per-cpu data in x86_64 mode. BUG=b:194391185, b:179699789 TEST=Boot guybrush with CPU_INFO_V2 and verify BSP and APs have correct %gs segment. Verify cpu_info looks sane.

2021-06-16arch/x86/ioapic: Drop irq_on_fsb as a configurable itemKyösti Mälkki
APIC Serial Bus pins were removed with ICH5 already, so a choice 'irq_on_fsb = 0' would not take effect. The related register BOOT_CONFIG 0x3 is also not documented since ICH5. For emulation/qemu-q35 with ICH9 the choice INTERRUPT_ON_APIC_BUS was wrong and ignored as BOOT_CONFIG register emulation was never implemented. For ICH4 and earlier, the choice to use FSB can be made based on the installed CPU model but this is now just hardwired to match P4 CPUs of aopen/dxplplusu. For sb/intel/i82371eb register BOOT_CONFIG 0x3 is also not defined and the only possible operation mode there is APIC Serial Bus, which requires no configuration.

2020-04-29arch/x86: Implement RESET_VECTOR_IN_RAMFelix Held
Add support for devices with the reset vector pointing into DRAM. This is a specific implementation that assumes a paradigm of AMD Family 17h (a.k.a. "Zen"). Until the first ljmpl for protected mode, the core's state appears to software like other designs, and then the actual physical addressing becomes recognizable. These systems cannot implement cache-as-RAM as in more traditional x86 products. Therefore instead of reusing CAR names and variables, a substitute called "earlyram" is introduced. This change makes adjustments to CAR-aware files accordingly. Enable NO_XIP_EARLY_STAGES. The first stage is already in DRAM, and running subsequent stages as XIP in the boot device would reduce performance. Finally, add a new early_ram.ld linker file. Because all stages run in DRAM, they can be linked with their .data and .bss as normal, i.e. they don't need to rely on storage available only at a fixed location like CAR systems. The primary purpose of the early_ram.ld is to provide consistent locations for PRERAM_CBMEM_CONSOLE, TIMESTAMP regions, etc. across stages until cbmem is brought online.
