2023-06-01include/cpu/x86: Skip `wbinvd` on CPUs with cache self-snooping (SS)Subrata Banik
This patch refers and backport some of previous work from Linux Kernel (https://lore.kernel.org/all/1561689337-19390-3-git-send-email-ricardo. neri-calderon@linux.intel.com/T/#u) that optimizes the MTRR register programming in multi-processor systems by relying on the CPUID (self-snoop feature supported). Refer to the details below: Programming MTRR registers in multi-processor systems is a rather lengthy process as it involves flushing caches. As a result, the process may take a considerable amount of time. Furthermore, all processors must program these registers serially. `wbinvd` instruction is used to invalidate the cache line to ensure that all modified data is written back to memory. All logical processors are stopped from executing until after the write-back and invalidate operation is completed. The amount of time or cycles for WBINVD to complete will vary due to the size of different cache hierarchies and other factors. As a consequence, the use of the WBINVD instruction can have an impact on response time. As per measurements, around 98% of the time needed by the procedure to program MTRRs in multi-processor systems is spent flushing caches with wbinvd(). As per the Section 11.11.8 of the Intel 64 and IA 32 Architectures Software Developer's Manual, it is not necessary to flush caches if the CPU supports cache self-snooping (ss). "Flush all caches using the WBINVD instructions. Note on a processor that supports self-snooping, CPUID feature flag bit 27, this step is unnecessary." Thus, skipping the cache flushes can reduce by several tens of milliseconds the time needed to complete the programming of the MTRR registers: Platform Before After 12-core (14 Threads) MeteorLake 35ms 1ms BUG=b:260455826 TEST=Able to build and boot google/rex.

2023-06-01cpu/x86/cache: Call wbinvd only once CR0.CD is setJeremy Compostella
This patch removes the wbinvd call preceding CR0.CD setting in disable_cache() to improve the boot time performances. According to some experimental measurements, the wbinvd execution takes between 1.6 up and 6 milliseconds to complete so it is preferable to call it only when necessary. According to Intel Software Developer Manual Vol 3.A - 12.5.3 Preventing Caching section there is no need to flush and invalidate the cache before settings CR0.CD. The documented sequence consists in setting CR0.CD and then call wbinvd. We also could not find any extra requirements in the AMD64 Architecture Programmer’s Manual - Volume 2 - Memory System chapter. This extra wbinvd in coreboot disable_cache() function does not seem documented and looking into the history of the project got us all the way back to original commit 8ca8d7665d67 ("- Initial checkin of the freebios2 tree") from April 2003. Even the original disable_cache() implementation (see below) is a bit curious as the comment list two actions: 1. Disable cache cover by line 74, 75 and 77 2. Write back the cache and flush TLB - Line 78 But it does not provide any explanation for the wbinvd call line 76. 68 static inline void disable_cache(void) 69 { 70 unsigned int tmp; 71 /* Disable cache */ 72 /* Write back the cache and flush TLB */ 73 asm volatile ( 74 "movl %%cr0, %0\n\t" 75 "orl $0x40000000, %0\n\t" 76 "wbinvd\n\t" 77 "movl %0, %%cr0\n\t" 78 "wbinvd\n\t" 79 :"=r" (tmp) 80 ::"memory"); 81 } BUG=b/260455826 TEST=Successful boot on Skolas and Rex board Change-Id: I08c6486dc93c4d70cadc22a760d1b7e536e85bfa Signed-off-by: Jeremy Compostella <jeremy.compostella@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/75474 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Subrata Banik <subratabanik@google.com> Reviewed-by: Himanshu Sahdev <himanshu.sahdev@intel.com>
2023-05-31cpu/x86/mp_init: Use clflush to write SIPI data back to RAMJeremy Compostella
Improve boot time performances by replacing the wbinvd instruction with multiple clflush to ensure that the SIPI data is written back to RAM. According to some experimental measurements, the wbinvd execution takes between 1.6 up and 6 milliseconds to complete. In the case of the SIPI data, wbinvd unnecessarily flushes and invalidates the entire cache. Indeed, the SIPI module is quite small (about 400 bytes) and cflush'ing the associated cache lines is almost instantaneous, typically less than 100 microseconds.

2023-03-13cpu/x86/cache: CLFLUSH programs to memory before runningArthur Heymans
When cbmem is initialized in romstage and postcar placed in the stage cache + cbmem where it is run, the assumption is made that these are all in UC memory such that calling INVD in postcar is OK. For performance reasons (e.g. postcar decompression) it is desirable to cache cbmem and the stage cache during romstage. Another reason is that AGESA sets up MTRR during romstage to cache all dram, which is currently worked around by using additional MTRR's to make that UC. TESTED on asus/p5ql-em, up/squared on both regular and S3 resume bootpath. Sometimes there are minimal performance improvements when cbmem is cached (few ms).

2022-12-07mb,sb,soc/intel: Drop useless IO trap handlersKyösti Mälkki
There are four requirements for the SMI to hit a printk() this commit now removes. Build must have DEBUG_SMI=y, otherwise any printk() is a no-op inside SMM. ASL must have a TRAP() with argument 0x99 or 0x32 for SMIF value. Platform needs to have IO Trap #3 enabled at IO 0x800. The SMI monitor must call io_trap_handler for IO Trap #3. At the moment, only getac/p470 would meet the above criteria with TRAP(0x32) in its DSDT _INI method. The ASL ignores any return value of TRAP() calls made. A mainboard IO trap handler should have precedence over a southbridge IO trap handler. At the moment we seem to have no cases of the latter to support, so remove the latter.

2022-11-23cpu/intel/car: Define post codesMartin Roth
This moves a lot of post code values, but unifies them between platforms, so that the same value means the same thing as much as possible. The P4-netburst code was the most extensive and most different, so that dictated the majority of the values. Three were two values there that didn't match the other files, so those two values, 0x22 & 0x29 have duplicate entries in the table. The rest of the entries are similar between platforms, though the values for many of them were moved to match the P4-netburst values. POST_BOOTBLOCK and POST_POSTCAR values are intended to eventually become global, while POST_SOC would be specific to the Intel platforms.

2022-09-15soc/amd: Do SMM relocation via MSRArthur Heymans
AMD CPUs have a convenient MSR that allows to set the SMBASE in the save state without ever entering SMM (e.g. at the default 0x30000 address). This has been a feature in all AMD CPUs since at least AMD K8. This allows to do relocation in parallel in ramstage and without setting up a relocation handler, which likely results in a speedup. The more cores the higher the speedup as relocation was happening sequentially. On a 4 core AMD picasso system this results in 33ms boot speedup. TESTED on google/vilboz (Picasso) with CONFIG_SMI_DEBUG: verify that SMM is correctly relocated with the BSP correctly entering the smihandler.

In this case we need to power on the UART when entering SMM, and then power it off before we exit.

2022-03-09cpu/x86/smm,lib/cbmem_console: Enable CBMEMC when using DEBUG_SMIRaul E Rangel
This change will allow the SMI handler to write to the cbmem console buffer. Normally SMIs can only be debugged using some kind of serial port (UART). By storing the SMI logs into cbmem we can debug SMIs using `cbmem -1`. Now that these logs are available to the OS we could also verify there were no errors in the SMI handler. Since SMM can write to all of DRAM, we can't trust any pointers provided by cbmem after the OS has booted. For this reason we store the cbmem console pointer as part of the SMM runtime parameters. The cbmem console is implemented as a circular buffer so it will never write outside of this area. BUG=b:221231786 TEST=Boot non-serial FW with DEBUG_SMI and verified SMI messages are visible when running `cbmem -1`. Perform a suspend/resume cycle and verify new SMI events are written to the cbmem console log.

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.

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.

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.

2021-07-17cpu/intel: Add dedicated file to grow Intel CPUIDsSubrata Banik
This patch removes all local `CPUID_` macros from SoC directories and creates a common cpu_ids.h inside include/cpu/intel/cpu_ids.h. SoC users are expected to add any new CPUID support into cpu_ids.h and include 'cpu/intel/cpu_ids.h' into respective files that look for `CPUID_` macro. Note: CPUIDs for HSW, BDW and Quark are still inside the respective directory.
