2024-01-16device: Add support for multiple PCI segment groupsFelix Held
Add initial support for multiple PCI segment groups. Instead of modifying secondary in the bus struct introduce a new segment_group struct element and keep existing common code. Since all platforms currently only use 1 segment this is not a functional change. On platforms that support more than 1 segment the segment has to be set when creating the PCI domain.

2024-01-12device/Kconfig: Add an option to allocate above 4G by defaultArthur Heymans
Historically resource allocation in coreboot was 32bit x86 thing. To remain compatible with this behavior (e.g. to keep 32bit payloads happy), resource allocation limits resources to 32 bits unless explicitly overridden. However this behavior is not always appropriate: e.g. on non x86 platforms the PCIe mem decode window could be above 4G. Another case on x86 is where the decode window(s) below 4G are not adequate for fitting all resources and the payload is 64bit capable (e.g. Linux). This adds a Kconfig flag to override the behavior to limit resources to 32bit by default and to allocate resources according to the real hardware limits.

2023-12-22x86: Separate CPU and SoC physical address sizeJeremy Compostella
The physical address size of the System-on-Chip (SoC) can be different from the CPU physical address size. These two different physical address sizes should be used for settings of their respective field. For instance, the physical address size related to the CPU should be used for MTRR programming while the physical address size of the SoC should be used for MMIO resource allocation. Typically, on Meteor Lake, the CPUs physical address size is 46 if TME is disabled and 42 if TME is enabled but Meteor Lake SoC physical address size is always 42. As a result, MTRRs should reflect the TME status while coreboot MMIO resource allocator should always use 42 bits. This commit introduces `SOC_PHYSICAL_ADDRESS_WIDTH' Kconfig to set the physical address size of the SoC for those SoCs.

Even when this was not requested with the IORESOURCE_ABOVE_4G flag. Tested on kontron/ktqm77 where the issue could be reproduced with x86_64. Without the fix, boot hangs when trying to access the GMA MMIO registers of PCI 00:02.0, which were placed above 4G.

2023-06-22allocator_v4: Use memranges only for toplevelNico Huber
During phase 1 of the resource allocation we gather all the size requirements. Starting from the leafs of our devicetree, we cal- culate the requirements per bus, until we reach the resource do- main. However, because alignment plays a role, we can't just accumulate the sizes of all resources on a bus. Instead, we already sort all the resources per bus to predict their relative placement, inclu- ding alignment gaps. Then, phase 2 has to perform the final allo- cations with the exact same relative placement. This patch introduces a very simple mechanism to avoid repeating all the calculations: In phase 1, we note the relative `base` of each resource on a bus. And after we allocated all the resources directly below the domain in phase 2, we add the absolute `base` of bridge resources to the relative `base` of child resources. This saves most of the computational complexity in phase 2. How- ever, with a shallow devicetree with most devices directly below the domain, this won't have a measurable impact. Example after phase 1: domain | `-- bridge #0 | res #0, base 0x000000 (relative), | size 12M, align 8M | |-- device #0 | res #1, base 0x800000 (relative), | size 4M, align 4M | `-- bridge #1 | res #2, base 0x000000 (relative), | size 8M, align 8M | `-- device #1 res #3, base 0x000000 (relative), size 8M, align 8M After phase 2 allocation at the domain level (assuming res #0 got 0xa000000 assigned): domain | `-- bridge #0 | res #0, base 0xa000000 (absolute), | size 12M, align 8M | |-- device #0 | res #1, base 0x800000 (relative), | size 4M, align 4M | `-- bridge #1 | res #2, base 0x000000 (relative), | size 8M, align 8M | `-- device #1 res #3, base 0x000000 (relative), size 8M, align 8M Now, all we need to do is to add the `base` of bridge resources recursively. Starting with resources on the bus below bridge #0: domain | `-- bridge #0 | res #0, base 0xa000000 (absolute), | size 12M, align 8M | |-- device #0 | res #1, base 0xa800000 (absolute), | size 4M, align 4M | `-- bridge #1 | res #2, base 0xa000000 (absolute), | size 8M, align 8M | `-- device #1 res #3, base 0x000000 (relative), size 8M, align 8M And finally for resources on the bus below bridge #1: domain | `-- bridge #0 | res #0, base 0xa000000 (absolute), | size 12M, align 8M | |-- device #0 | res #1, base 0xa800000 (absolute), | size 4M, align 4M | `-- bridge #1 | res #2, base 0xa000000 (absolute), | size 8M, align 8M | `-- device #1 res #3, base 0xa000000 (absolute), size 8M, align 8M Change-Id: I70c700318a85f6760f27597730bc9c9a86dbe6b3 Signed-off-by: Nico Huber <nico.h@gmx.de> Reviewed-on: https://review.coreboot.org/c/coreboot/+/65420 Reviewed-by: Lean Sheng Tan <sheng.tan@9elements.com> Reviewed-by: Arthur Heymans <arthur@aheymans.xyz> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Felix Singer <service+coreboot-gerrit@felixsinger.de>
2023-06-22allocator_v4: Treat above 4G resources more nativelyNico Huber
We currently have two competing mechanisms to limit the placement of resources: 1. the explicit `.limit` field of a resource, and 2. the IORESOURCE_ABOVE_4G flag. This makes the resource allocator unnecessarily complex. Ideally, we would always reduce the `.limit` field if we want to "pin" a specific resource below 4G. However, as that's not done across the tree yet, we will use the _absence_ of the IORESOURCE_ABOVE_4G flag as a hint to implicitly lower the `limit` of a resource. In this patch, this is done inside the effective_limit() function that hides the flag from the rest of the allocator. To automatically place resources above 4G if their limit allows it, we have to allocate from top down. Hence, we disable the prompt for RESOURCE_ALLOCATION_TOP_DOWN and turn it on by default. Platforms that are incompatible should be fixed, but can also override the default as a temporary measure. One implication of the changes is that we act differently when a cold-plugged device reports a prefetchable resource with 32-bit limit. Before this change, we would fail to allocate the resource. After this change, it forces everything on the same root port below the 4G line. A possible solution to get completely rid of the IORESOURCE_ABOVE_4G flag would be rules to place resources of certain devices below 4G. For instance, the primary VGA device and storage and HID devices could be made available to a payload that can only address 32 bits. For now, effective_limit() provides us enough abstraction as if the `limit` would be the only variable to consider. With this, we get rid of all the special handling of above 4G resources during phase 2 of the allocator.

2023-06-01device/pci: Limit default domain memory windowNico Huber
When the default pci_domain_read_resources() is used, keep 32-bit memory resources below the limit given by CONFIG_DOMAIN_RESOURCE_32BIT_LIMIT. This serves as a workaround for missing/wrong reservations of chipset resources. This will help to get more stable results from our own allocator, but is far from a complete solution. Indvi- dual platform ASL code also needs to be considered, so the OS won't assign conflicting resources. Most platforms have reserved space between 0xfe000000 and the 4G barrier. So use that as a global default. In case of `soc/intel/common/`, use 0xe0000000 because this is what is advertised in ACPI and there are traces of resources below 0xfe000000 that are unknown to core- boot's C code (PCH_PRESERVED_BASE?). Tested on QEMU/Q35 and Siemens/Chili w/ and w/o top- down allocation. Fixes EHCI w/ top-down in QEMU.

Don't assume only one IO and one MEM domain resource. Currently the code is awkward for bridge devices where loops over resources are done twice. This would be avoided on top of other patches that improve the allocator (topic:allocator) by adding a top-down mode. However those patches break the tree and having the option to have multiple resources per type would make it easier to get those patches in without breaking the tree.

2023-05-19device/Kconfig: Reduce PCIe hotplug bus numbers and IO resourcesArthur Heymans
The rationale behind this change is that multiple nested bridges using a lot of bus numbers and IO resources is not likely to be a common hotplug setup. When there is a large amount of hotplug ports using 32 subordinate busses results in boot failures (e.g. make qemu). 8K IO busses for hotplug devices is also excessive in most use cases when only 64K is available in total (again make qemu results in failure to allocate resources but does boot to payload).

2023-03-02device/pciexp_device.c: Do not enable common clock if already activeWerner Zeh
The Common Clock Configuration (CCC) is a PCIe feature for cases where the upstream and downstream device of a link share the same reference clock. After a change in this setting a link re-training is mandatory to make it effective. On recent Intel platforms (tested on Elkhart Lake) the FSP code which is executed before coreboot performs the PCI scan already enumerates all PCI buses for its internal uses. While this is done, all the PCI express features of a link are configured, which includes CCC. If the link supports common clock, FSP performs the link re-training already. When the execution flow is returned to coreboot, the same link treatment is applied again (coded in 'pciexp_tune_dev()') and CCC is enabled a second time, just a few milliseconds after FSP did this already. Because enabling CCC requires a link re-training, there are two link re-trainings on the PCIe link within a few milliseconds (one from the FSP code and one from coreboot) which can lead to issues with a connected PCIe device on this link. In particular, link issues were discovered with a Pericom PCIe switch (PI7C9X2G608) on mc_ehl1 where the link has stalled for a while after the second re-training. This in turn leads to non-initialized PCI devices on the bus after coreboot has finished. This patch checks if CCC is already enabled on a link and does not perform the steps to enable it again in coreboot which safes a link re-training (and thus execution time) and a potential link stability issue. Test=Check log output on mc_ehl1 which shows the following lines: [DEBUG] PCI: pci_scan_bus for bus 09 [DEBUG] PCI: 09:00.0 [8086/1533] enabled [INFO ] PCIe: Common Clock Configuration already enabled Change-Id: I747fa406a120a215de189d7252f160c8ea2e3716 Signed-off-by: Werner Zeh <werner.zeh@siemens.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/73310 Reviewed-by: Subrata Banik <subratabanik@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

2022-11-24src/device + util/sconfig: Introduce new device 'mdio'Mario Scheithauer
This patch extends the available device paths with a new device 'mdio'. MDIO is the 'Management Data Input/Output' called interface which is used to access an Ethernet PHY behind a MAC to change settings. The real payload data path is not handled by this interface. To address the PHY correctly on the MDIO bus, there is a 5 bit address needed, which often can be configured via pins on the mainboard. Therefore, the new introduced device has an 'addr' field to define its address. If one wants to use a MDIO device in devicetree, the syntax is straight forward (example): device mdio 0x2 on end As the MDIO interface is driven by the MAC, most likely this MDIO device will be hooked in as a child device of the (PCI attached) MAC device. With the new introduced ops_mdio a new interface is added to provide an API for read and write access over MDIO.

2022-11-04device/dram: Add kconfig options for memory typesMartin Roth
Currently, we're building support for all memory types into every board, and letting the linker remove anything that isn't needed. This is okay, but it'd be nice to be able to build in just what's actually needed. This change adds options to specify both what is used and what is not. By doing it that way, the default values don't change, but platforms can start removing support for memory types that are not needed. When all platforms (SoCs, CPUs and/or Northbridge chips) specify what memory types they support, the defaults on the options to use a particular memory type can be set to no, and the options not to use a memory type can be removed.

2022-09-04allocator_v4: Treat above 4G resources more nativelyNico Huber
We currently have two competing mechanisms to limit the placement of resources: 1. the explicit `.limit` field of a resource, and 2. the IORESOURCE_ABOVE_4G flag. This makes the resource allocator unnecessarily complex. Ideally, we would always reduce the `.limit` field if we want to "pin" a specific resource below 4G. However, as that's not done across the tree yet, we will use the _absence_ of the IORESOURCE_ABOVE_4G flag as a hint to implicitly lower the `limit` of a resource. In this patch, this is done inside the effective_limit() function that hides the flag from the rest of the allocator. To automatically place resources above 4G if their limit allows it, we have to allocate from top down. Hence, we disable the prompt for RESOURCE_ALLOCATION_TOP_DOWN if resources above 4G are requested. One implication of the changes is that we act differently when a cold-plugged device reports a prefetchable resource with 32-bit limit. Before this change, we would fail to allocate the resource. After this change, it forces everything on the same root port below the 4G line. A possible solution to get completely rid of the IORESOURCE_ABOVE_4G flag would be rules to place resources of certain devices below 4G. For instance, the primary VGA device and storage and HID devices could be made available to a payload that can only address 32 bits. For now, effective_limit() provides us enough abstraction as if the `limit` would be the only variable to consider. With this, we get rid of all the special handling of above 4G resources during phase 2 of the allocator. Which saves us about 20% of the code :D Change-Id: I4c7fcd1f5146f6cc287bd3aa5582da55bc5d6955 Signed-off-by: Nico Huber <nico.h@gmx.de> Reviewed-on: https://review.coreboot.org/c/coreboot/+/65413 Reviewed-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

2022-08-17pciexp_device: Join pciexp_find_(next_)extended_cap() APIsNico Huber
Move the `offset` parameter into pciexp_find_extended_cap(). If it's called with `0`, we start a new search. If it's an existing offset, we continue the search. This makes it easier to search for multiple occurences of a capa- bility in a single loop.

2022-08-15pciexp_device: Fix pciexp_find_next_extended_cap()Nico Huber
If we already encountered the last extended capability in the list, we'd call pciexp_get_ext_cap_offset() with `offset == 0`. So it also needs to check if the passed offset is valid. As there were no callers of pciexp_find_next_extended_cap() yet, pciexp_get_ext_cap_offset() was only ever called with `PCIE_EXT_CAP_OFFSET`.

2022-08-13device: Skip not assigned resources during global resource searchShuo Liu
It's possible that some BARs are not got their resource successfully mapped, e.g. when these BARs are too large to fit into the available MMIO window. Not assigned resources might be with base address as 0x0. During global resource search, these not assigned resources should not be picked up. One example is MTRR calculation. MTRR calculation is based on global memory ranges. An unmapped BAR whose base is left as 0x0 will be mistakenly picked up and recognized as an UC range starting from 0x0.

2022-08-13payloads/tianocore: Rename TianoCore to edk2Sean Rhodes
coreboot uses TianoCore interchangeably with EDK II, and whilst the meaning is generally clear, it's not the payload it uses. EDK II is commonly written as edk2. coreboot builds edk2 directly from the edk2 repository. Whilst it can build some components from edk2-platforms, the target is still edk2.

2022-08-07pciexp_device: Handle unsupported requests in pciexp_get_ext_cap_offset()Bill XIE
Looking into pciexp_get_ext_cap_offset() it seems a little hackish and prone to endless loops. Either it should limit the loop or bail out when pci_read_config32() returns 0xffffffff, meaning "Unsupported Requests". This commit fixes an endless loop when the queried PCIe device is downstream of a legacy PCI bus which doesn't support extended config space, thus pci_read_config32() will return 0xffffffff, for example, the combination below with CONFIG_PCIEXP_SUPPORT_RESIZABLE_BARS enabled.
