2022-03-08timestamps: Rename timestamps to make names more consistentJakub Czapiga
This patch aims to make timestamps more consistent in naming, to follow one pattern. Until now there were many naming patterns: - TS_START_*/TS_END_* - TS_BEFORE_*/TS_AFTER_* - TS_*_START/TS_*_END This change also aims to indicate, that these timestamps can be used to create time-ranges, e.g. from TS_BOOTBLOCK_START to TS_BOOTBLOCK_END.

2022-02-24nb/intel/ironlake: Fix some quickpath init magicAngel Pons
Correct some Quickpath initialisation steps according to findings from two different Intel reference code binaries as well as MCHBAR register dump comparisons between vendor firmware and coreboot. The MSR_TURBO_POWER_CURRENT_LIMIT information comes from EDK2 sources. Tested on Apple iMac 10,1 (Clarkdale, aka desktop Ironlake), QPI init now completes successfully instead of causing hangs before raminit. Also tested on HP ProBook 6550b (Arrandale, aka mobile Ironlake), still reaches payload (e.g. TianoCore).

2022-02-10Revert "cpu/x86/lapic: Unconditionally use CPUID leaf 0xb if available"Felix Held
This reverts commit ceaf959678905f44a54a116f37bd15acab5d4608. The AMD Picasso SoC doesn't support x2APIC and neither advertises the presence of its support via bit 21 in EAX of CPUID leaf 1 nor has the bit 10 in the APIC base address MSR 0x1b set, but it does have 0xd CPUID leaves, so just checking for the presence of that CPUID leaf isn't sufficient to be sure that EDX of the CPUID leaf 0xb will contain a valid APIC ID. In the case of Picasso EDX of the CPUID leaf 0xb returns 0 for all cores which causes coreboot to get stuck somewhere at the end of MP init. I'm not 100% sure if we should additionally check bit 21 in EAX of CPUID function 1 is set instead of adding back the is_x2apic_mode check. TEST=Mandolin with a Picasso SoC boots again.

2022-02-07treewide: Remove "ERROR: "/"WARN: " prefixes from log messagesJulius Werner
Now that the console system itself will clearly differentiate loglevels, it is no longer necessary to explicitly add "ERROR: " in front of every BIOS_ERR message to help it stand out more (and allow automated tooling to grep for it). Removing all these extra .rodata characters should save us a nice little amount of binary size. This patch was created by running find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';' and doing some cursory review/cleanup on the result.

Selecting CPU_X86_CACHE_HELPER only added the x86_enable_cache wrapper function around enable_cache which additionally wrote a POST code to port 0x80 and printed a message to the console. This function was only called during multi-processor initialization in ramstage via the init function pointer in the CPU's device operations struct and was run on all cores, so the message on the console was printed once per CPU core. This patch replaces all x86_enable_cache calls by calls to enable_cache and removes the wrapper function and the Kconfig symbol CPU_X86_CACHE_HELPER which was used to only add this when the corresponding CPUs used the x86_enable_cache wrapper function.

With using a Kconfig option to add the x86 LAPIC support code to the build, there's no need for adding the corresponding directory to subdirs in the CPU/SoC Makefile. Comparing which CPU/SoC Makefiles added (cpu/)x86/mtrr and (cpu/)x86/lapic before this and the corresponding MTRR code selection patch and having verified that all platforms added the MTRR code on that patch shows that soc/example/min86 and soc/intel/quark are the only platforms that don't end up selecting the LAPIC code. So for now the default value of CPU_X86_LAPIC is chosen as y which gets overridden to n in the Kconfig of the two SoCs mentioned above.

All x86-based CPUs and SoCs in the coreboot tree end up including the Makefile in cpu/x86/mtrr, so include this directly in the Makefile in cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is selected be default could be added and the new CPU/SoC without MTRR support can override this option that then will be used in the Makefile to guard adding the Makefile from the cpu/x86/mtrr sub-directory. In cpu/intel all models except model 2065X and 206AX are selcted by a socket and rely on the socket's Makefile.inc to add x86/mtrr to the subdirs, so those models don't add x86/mtrr themselves. The Intel Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the subdirs. The Intel Xeon SP SoC directory contains two sub-folders for different versions or generations which both add x86/mtrr to the subdirs in their Makefiles.

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.

The %fs and %gs segment are typically used to implement thread local storage or cpu local storage. We don't currently use these in coreboot, so there is no reason to map them. By setting the segment index to 0, it disables the segment. If an instruction tries to read from one of these segments an exception will be raised. The end goal is to make cpu_info() use the %gs segment. This will remove the stack alignment requirements and fix smm_do_relocation.
