2024-05-23device: drop unnecessary CHECK_REV_IN_OPROM_NAME optionFelix Held
The CHECK_REV_IN_OPROM_NAME Kconfig option was introduced to solve the problem of the PCI VID/DID combination of the Picasso iGPU not being sufficient information to know which VGA BIOS file to run, so a new function that additionally checks the PCI revision of that device was introduced. Later it turned out that there might be a case where even that isn't sufficient, so the soc_is_raven2() function is used in the remap function to always use the correct VBIOS file. Picasso is the only SoC that selected the CHECK_REV_IN_OPROM_NAME Kconfig option, so all other SoCs are unaffected by this change. Now that we use the VBIOS images with only the PCI VID and DID in the CBFS file name for Picasso, SeaBIOS will find the VBIOS with the same ID as the iGPU in CBFS and we don't need the workaround to add a third VBIOS image via VGA_BIOS_DGPU_* that has the name that SeaBIOS expects. This will result in SeaBIOS now running the VBIOS that has the same PCI VID/DID as the hardware which will be the wrong one in the RV2 silicon showing the PCO silicon PCI VID/DID, but that was also the case with the VGA_BIOS_DGPU_* workaround where the board's Kconfig just selected one of the two possible images during build time and hoped that it was the correct one for that actual hardware. The only board where this patch might cause a regression compared to the old behavior is the AMD Cereme reference board with Pollock APU, but I'm not even sure if any coreboot developer still has one of those boards, so I'm willing to accept that. To properly solve the problem with SeaBIOS using the correct VBIOS file in all cases, we'd need to generate that info during coreboot runtime and somehow pass it to SeaBIOS, but that's out of scope for this patch. TEST=On Mandolin with PCO silicon, the display output in both SeaBIOS and Ubuntu still works. Booting Windows 10 via the pre-built EDK2 payload that I'm using also resulted in the display output working.

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.

This option is nowhere selected and there is only a single case left where it's used. Guarding the check in pci_rom_load() seems like a bad idea: As the code would be copying all VGA ROMs to the same location, it would be only working by chance (if the last encoun- tered ROM is the right one). Hence, drop the guard and always check for the correct device.

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. Which saves us about 20% of the code :D An earlier version of this change (commit 117e43611548) had to be reverted because of missing resource reservations in platform code. This is worked around now with commit ae81497cb6c7 (device/pci: Limit default domain memory window).

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.

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).

2022-03-15i2c: Add configurable I2C transfer timeoutJes Klinke
This patch introduces CONFIG_I2C_TRANSFER_TIMEOUT_US, which controls how long to wait for an I2C devices to produce/accept all the data bytes in a single transfer. (The device can delay transfer by stretching the clock of the ack bit.) The default value of this new setting is 500ms. Existing code had timeouts anywhere from tens of milliseconds to a full second beween various drivers. Drivers can still have their own shorter timeouts for setup/communication with the I2C host controller (as opposed to transactions with I2C devices on the bus.) In general, the timeout is not meant to be reached except in situations where there is already serious problem with the boot, and serves to make sure that some useful diagnostic output is produced on the console.

2022-02-16device: Add support for PCIe Resizable BARsTim Wawrzynczak
Section 7.8.6 of the PCIe spec (rev 4) indicates that some devices can indicates support for "Resizable BARs" via a PCIe extended capability. When support this capability is indicated by the device, the size of each BAR is determined in a different way than the normal "moving bits" method. Instead, a pair of capability and control registers is allocated in config space for each BAR, which can be used to both indicate the different sizes the device is capable of supporting for the BAR (powers-of-2 number of bits from 20 [1 MiB] to 63 [8 EiB]), and to also inform the device of the size that the allocator actually reserved for the MMIO range. This patch adds a Kconfig for a mainboard to select if it knows that it will have a device that requires this support during PCI enumeration. If so, there is a corresponding Kconfig to indicate the maximum number of bits of address space to hand out to devices this way (again, limited by what devices can support and each individual system may want to support, but just like above, this number can range from 20 to 63) If the device can support more bits than this Kconfig, the resource request is truncated to the number indicated by this Kconfig.

All boards that are trying to use MIPI panels eventually run into the problem that they need to store physical parameters and a list of DCS initialization commands for each panel, and these commands can be very different (e.g. a large amount of very short commands, a few very large commands, etc.). Finding a data format to fit all these different cases efficiently into the same structures keeps being a challenge, and the Kukui mainboard already once put a lot of effort into designing a clean, flexible and efficient solution for this. This patch moves that framework into a common src/device/mipi/ library where it can be used by other boards as well.

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.

2020-05-26device: Add support for resource allocator v4Furquan Shaikh
This change adds back support for the resource allocator using multiple ranges as originally landed in CB:39486(commit hash 3b02006) and reverted in CB:41413(commit hash 6186cbc). The new resource allocator can be selected by Kconfig option RESOURCE_ALLOCATOR_V4. It was identified that there are some AMD chipsets in the tree that do not really work well with the dynamic resource allocation. Until these chipsets are fixed, old (v3) and new (v4) of the resource allocator need to live side-by-side in the tree. There were some other chipsets in the tree which originally demonstrated problems with the new resource allocator, but have been since fixed in the tree. This change picks up the same additions as performed in CB:39486 along with the following changes: 1. Changes to avoid fixed resources in the entire tree. Use of search_bus_resources() is replaced with a walk of the entire tree in avoid_fixed_resources(). This is required to ensure that all fixed resources added to any device (including domain) are taken into consideration to avoid overlap during dynamic resource allocation. 2. Changes to set up alignment for memranges when initializing them. This is done to ensure that the right granularity is used for IORESOURCE_IO(no special alignment) and IORESOURCE_MEM(4KiB) resource requests. 3. mark_resource_invalid() is dropped as the resource no longer needs to be marked in any special way if allocation is not being done. Instead setting of IORESOURCE_ASSIGNED flag is skipped in this case. 4. initialize_memranges() is updated to check IORESOURCE_ASSIGNED instead of base == limit. Original commit message: This change updates the resource allocator in coreboot to allow using multiple ranges for resource allocation rather than restricting available window to a single base/limit pair. This is done in preparation to allow 64-bit resource allocation. Following changes are made as part of this: a) Resource allocator still makes 2 passes at the entire tree. The first pass is to gather the resource requirements of each device under each domain. It walks recursively in DFS fashion to gather the requirements of the leaf devices and propagates this back up to the downstream bridges of the domain. Domain is special in the sense that it has fixed resource ranges. Hence, the resource requirements from the downstream devices have no effect on the domain resource windows. This results in domain resource limits being unmodified after the first pass. b) Once the requirements for all the devices under the domain are gathered, resource allocator walks a second time to allocate resources to downstream devices as per the requirements. Here, instead of maintaining a single window for allocating resources, it creates a list of memranges starting with the resource window at domain and then applying constraints to create holes for any fixed resources. This ensures that there is no overlap with fixed resources under the domain. c) Domain does not differentiate between mem and prefmem. Since they are allocated space from the same resource window at the domain level, it considers all resource requests from downstream devices of the domain independent of the prefetch type. d) Once resource allocation is done at the domain level, resource allocator walks down the downstream bridges and continues the same process until it reaches the leaves. Bridges have separate windows for mem and prefmem. Hence, unlike domain, the resource allocator at bridge level ensures that downstream requirements are satisfied by taking prefetch type into consideration. e) This whole 2-pass process is performed for every domain in the system under the assumption that domains do not have overlapping address spaces. Noticeable differences from previous resource allocator: a) Changes in print logs observed due to flows being slightly different. b) Base, limit and size of domain resources are no longer updated based on downstream requirements. c) Memranges are used instead of a single base/limit pair for determining resource allocation. d) Previously, if a resource request did not fit in the available base/limit window, then the resource would be allocated over DRAM or any other address space defeating the principle of "no overlap". With this change, any time a resource cannot fit in the available ranges, it complains and ensures that the resource is effectively disabled by setting base same as the limit. e) Resource allocator no longer looks at multiple links to determine the right bus for a resource. None of the current boards have multiple buses under any downstream device of the domain. The only device with multiple links seems to be the cpu cluster device for some AMD platforms.

2020-05-26device: Move resource allocation into a separate compilation unitFurquan Shaikh
This change moves the resource allocator functions out of device.c and into two separate files: 1. resource_allocator_v3.c: This is the old implementation of resource allocator that uses a single window for resource allocation. It is required to support some AMD chipsets that do not provide an accurate map of allocated resources by the time the allocator runs. They work fine with the old allocator since it restricts itself to allocations in a single window at the top of the 4G space. 2. resource_allocator_common.c: This file contains the functions that can be shared by the old and new resource allocator. Entry point into the resource allocation is allocate_resources() which can be implemented by both old and new allocators. This change also adds a Kconfig option RESOURCE_ALLOCATOR_V3 which enables the old resource allocator. This config option is enabled by default currently, but in the following CLs this will be enabled only for the broken boards. Reason for this split: Both the old and new resource allocators need to be retained in the tree until the broken chipsets are fixed.

This change adds a Kconfig option to request allocation of prefetch memory for hotplug devices above the 4G boundary. In order to select this option by default and still allow users to disable this if required, another option is added to request allocation of prefetch memory below 4G boundary which defaults to n but can be overriden by mainboards. Without this change, if the number of pciexp bridges supporting hot-plug is more than 4 or if the reserved prefetch memory size for hot-plug cases was increased, then the resource allocator would fail to satisfy the resource requirement below 4G boundary.

Because searching CBFS takes a non-trivial amount of time, only enable the option if it's needed.

2020-02-05pciexp: Add support for allocating PCI express hotplug resourcesJeremy Soller
This change adds support for allocating resources for PCI express hotplug bridges when PCIEXP_HOTPLUG is selected. By default, this will add 32 PCI subordinate numbers (buses), 256 MiB of prefetchable memory, 8 MiB of non-prefetchable memory, and 8 KiB of I/O space to any device with the PCI_EXP_SLTCAP_HPC bit set in the PCI_EXP_SLTCAP register, which indicates hot-plugging capability. The resource allocation is configurable, please see the PCIEXP_HOTPLUG_* variables in src/device/Kconfig. In order to support the allocation of hotplugged PCI buses, a new field is added to struct device called hotplug_buses. This is defaulted to zero, but when set, it adds the hotplug_buses value to the subordinate value of the PCI bridge. This allows devices to be plugged in and unplugged after boot. This code was tested on the System76 Darter Pro (darp6). Before this change, there are not enough resources allocated to the Thunderbolt PCI bridge to allow plugging in new devices after boot. This can be worked around in the Linux kernel by passing a boot param such as: pci=assign-busses,hpbussize=32,realloc This change makes it possible to use Thunderbolt hotplugging without kernel parameters, and attempts to match closely what our motherboard manufacturer's firmware does by default.

Showing the bootsplash afterwards guarantees to have the same interface into all the vga drivers. This is by far from ideal, as it only allows for a single driver at compile-time and should be adapted in the future. It was tested on the wip razer blade stealth using vgabios @ 1280x1024 and also in Qemu @ 1280x1024. By default the qemu framebuffer will be initialized in 800x600@32.

2017-06-08device/Kconfig: Put gfx init methods into a `choice`Nico Huber
Provide all gfx init methods as a Kconfig `choice`. This elimates the option to select native gfx init along with running a Video BIOS. It's been only theoretically useful in one corner case: Hybrid graphics where only one controller is supported by native gfx init. Though I suppose in that case it's fair to assume that one would use SeaBIOS to run the VBIOS. For the case that we want the payload to initialize graphics or no pre-boot graphics at all, the new symbol NO_GFX_INIT was added to the choice. If multiple options are available, the default is chosen as follows: * NO_GFX_INIT, if we add a Video BIOS and the payload is SeaBIOS, * VGA_ROM_RUN, if we add a Video BIOS and the payload is not SeaBIOS, * NATIVE_VGA_INIT, if we don't add a Video BIOS. As a side effect, libgfxinit is now an independent choice.
