2020-10-11pci_device: Add a helper function for determining if PCI device is wake sourceFurquan Shaikh
This change adds a helper function `pci_dev_is_wake_source()` that checks PME_STATUS and PME_ENABLE bits in PM control and status register to determine if the given device is the source of wake.

2020-09-14soc/intel/common/cpu: Update COS mask calculation for NEM enhanced modeAamir Bohra
Update the COS mask calculation to accomodate the RW data as per SoC configuration. Currently only one way is allocated for RW data and configured for non-eviction. For earlier platform this served fine, and could accomodate a RW data up to 256Kb. Starting TGL and JSL, the DCACHE_RAM_SIZE is configured for 512Kb, which cannot be mapped to a single way. Hence update the number of ways to be configured for non- eviction as per total LLC size. The total LLC size/ number of ways gives the way size. DCACHE_RAM_SIZE/ way size gives the number of ways that need to be configured for non- eviction, instead of harcoding it to 1. TGL uses MSR IA32_CR_SF_QOS_MASK_1(0x1891) and IA32_CR_SF_QOS_MASK_2(0x1892) as COS mask selection register and hence needs to be progarmmed accordingly. Also JSL and TGL platforms the COS mask selection is mapped to bit 32:33 of MSR IA32_PQR_ASSOC(0xC8F) and need to be updated in edx(maps 63:32) before MSR write instead of eax(maps 31:0).

2020-08-31device: Add method to configure bus mastering based on KconfigFelix Singer
The bus master bit is set at many places in coreboot's code, but the reason for that is not quite clear. We examined not setting the bus master bit whereever possible and tried booting without it, which worked fine for internal PCI devices but not for PCIe. As a PCIe device we used a Samsung M.2 NVMe SSD. For security reasons, we would like to disable bus mastering where possible. Depending on the device, bus mastering might get enabled by the operating system (e.g. for iGPU) and it might be required for some devices to work properly. However, the idea is to leave it disabled and configure the IOMMU first before enabling it. To have some sort of "backwards compatibility", add a method which configures bus mastering based on an additional config option. Since CB:42460 makes usage of this treewide, enable it by default to keep the current behaviour for now. Tested with Siemens/Chili, a Coffee Lake based platform.

2020-08-24mrc_cache: Add mrc_cache fetch functions to support non-x86 platformsShelley Chen
Create two new functions to fetch mrc_cache data (replacing mrc_cache_get_current): - mrc_cache_load_current: fetches the mrc_cache data and drops it into the given buffer. This is useful for ARM platforms where the mmap operation is very expensive. - mrc_cache_mmap_leak: fetch the mrc_cache data and puts it into a given buffer. This is useful for platforms where the mmap operation is a no-op (like x86 platforms). As the name mentions, we are not freeing the memory that we allocated with the mmap, so it is the caller's responsibility to do so. Additionally, we are replacing mrc_cache_latest with mrc_cache_get_latest_slot_info, which does not check the validity of the data when retrieving the current mrc_cache slot. This allows the caller some flexibility in deciding where they want the mrc_cache data stored (either in an mmaped region or at a given address).

2020-08-15cpu/x86/smm: Introduce SMM module loader version 2Rocky Phagura
Xeon-SP Skylake Scalable Processor can have 36 CPU threads (18 cores). Current coreboot SMM is unable to handle more than ~32 CPU threads. This patch introduces a version 2 of the SMM module loader which addresses this problem. Having two versions of the SMM module loader prevents any issues to current projects. Future Xeon-SP products will be using this version of the SMM loader. Subsequent patches will enable board specific functionality for Xeon-SP. The reason for moving to version 2 is the state save area begins to encroach upon the SMI handling code when more than 32 CPU threads are in the system. This can cause system hangs, reboots, etc. The second change is related to staggered entry points with simple near jumps. In the current loader, near jumps will not work because the CPU is jumping within the same code segment. In version 2, "far" address jumps are necessary therefore protected mode must be enabled first. The SMM layout and how the CPUs are staggered are documented in the code. By making the modifications above, this allows the smm module loader to expand easily as more CPU threads are added. TEST=build for Tiogapass platform under OCP mainboard. Enable the following in Kconfig. select CPU_INTEL_COMMON_SMM select SOC_INTEL_COMMON_BLOCK_SMM select SMM_TSEG select HAVE_SMI_HANDLER select ACPI_INTEL_HARDWARE_SLEEP_VALUES Debug console will show all 36 cores relocated. Further tested by generating SMI's to port 0xb2 using XDP/ITP HW debugger and ensured all cores entering and exiting SMM properly. In addition, booted to Linux 5.4 kernel and observed no issues during mp init.

2020-08-03assert.h: Try to evaluate assertions at compile timeJulius Werner
Many places in coreboot seem to like to do things like assert(CONFIG(SOME_KCONFIG)); This is somewhat suboptimal since assert() is a runtime check, so you don't see that this fails until someone actually tries to boot it even though the compiler is totally aware of it already. We already have the dead_code() macro to do this better: if (CONFIG(SOME_KCONFIG)) dead_code(); Rather than fixing all these and trying to carefully educate people about which type of check is more appropriate in what situation, we can just employ the magic of __builtin_constant_p() to automatically make the former statement behave like the latter.

2020-07-30smbios: Fix type 17 for Windows 10Patrick Rudolph
The `GetPhysicallyInstalledSystemMemory` API call, at least on Windows 10, returns an error if SMBIOS tables are invalid. Various tools use this API call and don't operate correctly if this fails. For example, the "Intel Processor Diagnostic Tool" program is affected. Windows then guesses the physical memory size by accumulating entries from the firmware-provided memory map, which results in a total memory size that is slightly lower than the actual installed memory capacity. To fix this issue, add the handle to a type 16 entry to all type 17 entries. Add new fields to struct memory_info and fill them in Intel common code. Use the introduced variables to fill type 16 in smbios.c and provide a handle to type 17 entries. Besides keeping the current behaviour on intel/soc/common platforms, the type 16 table is also emitted on platforms that don't explicitly fill it, by using the existing fields of struct memory_info. Tested on Windows 10: The GetPhysicallyInstalledSystemMemory API call doesn't return an error anymore and the installed memory is now being reported as 8192 MiB.

2020-07-28src: Never set ISA Enable on PCI bridgesAngel Pons
Looks like no one really knows what this bit would be useful for, nor when it would need to be set. Especially if coreboot is setting it even on PCI *Express* bridges. Digging through git history, nearly all instances of setting it on PCIe bridges comes from i82801gx, for which no reason was given as to why this would be needed. The other instances in Intel code seem to have been, unsurprisingly, copy-pasted. Drop all uses of this definition and rename it to avoid confusion. The negation in the name could trick people into setting this bit again. Tested on Asrock B85M Pro4, no visible difference.

2020-07-24assert.h: Do not use __FILE__ nor __LINE__ on timeless buildsAngel Pons
When refactoring, one can move code around quite a bit while preserving reproducibility, unless there is an assert-style macro somewhere... As these macros use __FILE__ and __LINE__, just moving them is enough to change the resulting binary, making timeless builds rather useless. To improve reproducibility, do not use __FILE__ nor __LINE__ inside the assert-style macros. Instead, use hardcoded values. Plus, mention that timeless builds lack such information in place of the file name, so that grepping for the printed string directs one towards this commit. And for the immutable line number, we can use 404: line number not found :-) Change-Id: Id42d7121b6864759c042f8e4e438ee77a8ac0b41 Signed-off-by: Angel Pons <th3fanbus@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/42196 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Julius Werner <jwerner@chromium.org>
