2021-03-15pciexp_device: Rewrite LTR configurationNico Huber
I was bugged by spurious "Failed to enable LTR" messages for years. Looking at the the current algorithm, it is flawed in multiple ways: * It looks like the author didn't know they implemented a recursive algorithm (pciexp_enable_ltr()) inside another recursive algorithm (pciexp_scan_bridge()). Thus, at every tree level, everything is run again for the whole sub- tree. * LTR is enabled no matter if `.set_ltr_max_latencies` is implemented or not. Leaving the endpoints' LTR settings at 0: They are told to always report zero tolerance. In theory, depending on the root-complex implementation, this may result in higher power consumption than without LTR messages. * `.set_ltr_max_latencies` is only considered for the direct parent of a device. Thus, even with it implemented, an endpoint below a (non-root) bridge may suffer from the 0 settings as described above. * Due to the double-recursive nature, LTR is enabled starting with the endpoints, then moving up the tree, while the PCIe spec tells us to do it in the exact opposite order. With the current implementation of pciexp_scan_bridge(), it is hard to hook anything in that runs for each device from top to bottom. So the proposed solution still adds some redundancy: First, for every device that uses pciexp_scan_bus(), we enable LTR if possible (see below). Then, when returning from the bus- scanning recursion, we enable LTR for every device and configure the maximum latencies (if supported). The latter runs again on all bridges, because it's hard to know if pciexp_scan_bus() was used for them. When to enable LTR: * For all devices that implement `.set_ltr_max_latencies`. * For all devices below a bridge that has it enabled already.

2021-03-12cpu/intel/microcode: Fix caching logic in intel_microcode_findFurquan Shaikh
CB:49896 added support in `intel_microcode_find()` to cache the found microcode for faster subsequent accesses. This works okay when the function succeeds in finding the microcode on BSP. However, if for any reason, `cpu_microcode_blob.bin` does not contain a valid microcode for the given processor, then the logic ends up attempting to find microcode again and again every time it is called (because `ucode_updates` is set to NULL on failed find, thus retriggering the whole find sequence every time). This leads to a weird race condition when multiple APs are running in parallel and executing this function. A snippet of the issues observed in the scenario described above: ``` ... microcode: Update skipped, already up-to-date ... Microcode header corrupted! ... ``` 1. AP reports that microcode update is being skipped since the current version matches the version in CBFS (even though there is no matching microcode update in CBFS). 2. AP reports microcode header is corrupted because it thinks that the data size reported in the microcode is larger than the file read from CBFS. Above issues occur because each time an AP calls `intel_microcode_find()`, it might end up seeing some intermittent state of `ucode_updates` and taking incorrect action. This change fixes this race condition by separating the logic for finding microcode into an internal function `find_cbfs_microcode()` and maintaining the caching logic in `intel_microcode_find()` using a boolean flag `microcode_checked`. BUG=b:182232187 TEST=Verified that `intel_microcode_find()` no longer makes repeated attempts to find microcode from CBFS if it failed the first time.

2021-03-08cbfs: Add cbfs_alloc() primitive and combine cbfs_load() and cbfs_map()Julius Werner
This patchs adds a new CBFS primitive that allows callers to pass in an allocator function that will be called once the size of the file to load is known, to decide on its final location. This can be useful for loading a CBFS file straight into CBMEM, for example. The new primitive is combined with cbfs_map() and cbfs_load() into a single underlying function that can handle all operations, to reduce the amount of code that needs to be duplicated (especially later when file verification is added). Also add a new variation that allows restraining or querying the CBFS type of a file as it is being loaded, and reorganize the documentation/definition of all these accessors and variations in the header file a little.

This patch pulls control of the memory pool serving allocations from the CBFS_CACHE memlayout area into cbfs.c and makes it a core part of the CBFS API. Previously, platforms would independently instantiate this as part of boot_device_ro() (mostly through cbfs_spi.c). The new cbfs_cache pool is exported as a global so these platforms can still use it to directly back rdev_mmap() on their boot device, but the cbfs_cache can now also use it to directly make allocations itself. This is used to allow transparent decompression support in cbfs_map().

2021-02-18rmodtool: Make memlayout symbols absolute and do not relocate themJulius Werner
Memlayout is a mechanism to define memory areas outside the normal program segment constructed by the linker. Therefore, it generally doesn't make sense to relocate memlayout symbols when the program is relocated. They tend to refer to things that are always in one specific spot, independent of where the program is loaded. This hasn't really hurt us in the past because the use case we have for rmodules (ramstage on x86) just happens to not really need to refer to any memlayout-defined areas at the moment. But that use case may come up in the future so it's still worth fixing. This patch declares all memlayout-defined symbols as ABSOLUTE() in the linker, which is then reflected in the symbol table of the generated ELF. We can then use that distinction to have rmodtool skip them when generating the relocation table for an rmodule. (Also rearrange rmodtool a little to make the primary string table more easily accessible to the rest of the code, so we can refer to symbol names in debug output.) A similar problem can come up with userspace unit tests, but we cannot modify the userspace relocation toolchain (and for unfortunate historical reasons, it tries to relocate even absolute symbols). We'll just disable PIC and make those binaries fully static to avoid that issue.

2021-01-11acpi,soc/intel/common: add support for Intel Low Power Idle TableMichael Niewöhner
Add support for the Intel LPIT table to support reading Low Power Idle Residency counters by the OS. On platforms supporting S0ix sleep states there can be two types of residencies: * CPU package PC10 residency counter (read from MSR via FFH interface) * PCH SLP_S0 assertion residency counter (read via memory mapped interface) With presence of one or both of these counters in the LPIT table, Linux dynamically adds the corresponding attributes to the cpuidle sysfs interface, that can be used to read the residency timers: * /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us * /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us The code in src/acpi implements generic LPIT support. Each SoC or platform has to implement `acpi_fill_lpit` to fill the table with platform-specific LPI state entries. This is done in this change for soc/intel/common, while being added as its own compilation unit, so SoCs not yet using common acpi code (like Skylake) can use it, too.

2020-12-28device + util/sconfig: introduce new device `gpio`Michael Niewöhner
Introduce a new device `gpio` that is going to be used for generic abstraction of gpio operations in the devicetree. The general idea behind this is that every chip can have gpios that shall be accessible in a very generic way by any driver through the devicetree. The chip that implements the chip-specific gpio operations has to assign them to the generic device operations struct, which then gets assigned to the gpio device during device probing. See CB:48583 for how this gets done for the SoCs using intelblocks/gpio. The gpio device then can be added to the devicetree with an alias name like in the following example: chip soc/whateverlake device gpio 0 alias soc_gpio on end ... end Any driver that requires access to this gpio device needs to have a device pointer (or multiple) and an option for specifying the gpio to be used in its chip config like this: struct drivers_ipmi_config { ... DEVTREE_CONST struct device *gpio_dev; u16 post_complete_gpio; ... }; The device `soc_gpio` can then be linked to the chip driver's `gpio_dev` above by using the syntax `use ... as ...`, which was introduced in commit 8e1ea52: chip drivers/ipmi use soc_gpio as gpio_dev register "bmc_jumper_gpio" = "GPP_D22" ... end The IPMI driver can then use the generic gpio operations without any knowlege of the chip's specifics: unsigned int gpio_val; const struct gpio_operations *gpio_ops; gpio_ops = dev_get_gpio_ops(conf->gpio_dev); gpio_val = gpio_ops->get(conf->bmc_jumper_gpio); For a full example have a look at CB:48096 and CB:48095. This change adds the new device type to sconfig and adds generic gpio operations to the `device_operations` struct. Also, a helper for getting the gpio operations from a device after checking them for NULL pointers gets added. Successfully tested on Supermicro X11SSM-F with CB:48097, X11SSH-TF with CB:48711 and OCP DeltaLake with CB:48672.

2020-12-03cbfs: Add verification for RO CBFS metadata hashJulius Werner
This patch adds the first stage of the new CONFIG_CBFS_VERIFICATION feature. It's not useful to end-users in this stage so it cannot be selected in menuconfig (and should not be used other than for development) yet. With this patch coreboot can verify the metadata hash of the RO CBFS when it starts booting, but it does not verify individual files yet. Likewise, verifying RW CBFSes with vboot is not yet supported. Verification is bootstrapped from a "metadata hash anchor" structure that is embedded in the bootblock code and marked by a unique magic number. This anchor contains both the CBFS metadata hash and a separate hash for the FMAP which is required to find the primary CBFS. Both are verified on first use in the bootblock (and halt the system on failure). The CONFIG_TOCTOU_SAFETY option is also added for illustrative purposes to show some paths that need to be different when full protection against TOCTOU (time-of-check vs. time-of-use) attacks is desired. For normal verification it is sufficient to check the FMAP and the CBFS metadata hash only once in the bootblock -- for TOCTOU verification we do the same, but we need to be extra careful that we do not re-read the FMAP or any CBFS metadata in later stages. This is mostly achieved by depending on the CBFS metadata cache and FMAP cache features, but we allow for one edge case in case the RW CBFS metadata cache overflows (which may happen during an RW update and could otherwise no longer be fixed because mcache size is defined by RO code). This code is added to demonstrate design intent but won't really matter until RW CBFS verification can be supported.

2020-12-02cbfs: Simplify load/map API names, remove type argumentsJulius Werner
This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file() to cbfs_map() and cbfs_load() respectively. This is supposed to be the start of a new, better organized CBFS API where the most common operations have the most simple and straight-forward names. Less commonly used variants of these operations (e.g. cbfs_ro_load() or cbfs_region_load()) can be introduced later. It seems unnecessary to keep carrying around "boot" in the names of most CBFS APIs if the vast majority of accesses go to the boot CBFS (instead, more unusual operations should have longer names that describe how they diverge from the common ones). cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly reap mappings when desired. A few new cbfs_unmap() calls are added to generic code where it makes sense, but it seems unnecessary to introduce this everywhere in platform or architecture specific code where the boot medium is known to be memory-mapped anyway. In fact, even for non-memory-mapped platforms, sometimes leaking a mapping to the CBFS cache is a much cleaner solution than jumping through hoops to provide some other storage for some long-lived file object, and it shouldn't be outright forbidden when it makes sense. Additionally, remove the type arguments from these function signatures. The goal is to eventually remove type arguments for lookup from the whole CBFS API. Filenames already uniquely identify CBFS files. The type field is just informational, and there should be APIs to allow callers to check it when desired, but it's not clear what we gain from forcing this as a parameter into every single CBFS access when the vast majority of the time it provides no additional value and is just clutter.

2020-12-02cbfs: Move more stuff into cbfs_boot_lookup()Julius Werner
cbfs_boot_locate() is supposed to be deprecated eventually, after slowly migrating all APIs to bypass it. That means common features (like RO-fallback or measurement) need to be moved to the new cbfs_boot_lookup(). Also export the function externally. Since it is a low-level API and most code should use the higher-level loading or mapping functions instead, put it into a new <cbfs_private.h> to raise the mental barrier for using this API (this will make more sense once cbfs_boot_locate() is removed from <cbfs.h>).
