* device: Add support for multiple PCI segment groupsFelix Held2024-01-161-0/+9
| | | | | | | | | | | | | | | | | | 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.

* device/Kconfig: Add an option to allocate above 4G by defaultArthur Heymans2024-01-121-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* allocator_v4: Treat above 4G resources more nativelyNico Huber2023-06-221-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* device/pci: Limit default domain memory windowNico Huber2023-06-011-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* device/Kconfig: Reduce PCIe hotplug bus numbers and IO resourcesArthur Heymans2023-05-191-6/+4
| | | | | | | | | | | | | | | | | | 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).

* i2c: Add configurable I2C transfer timeoutJes Klinke2022-03-151-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* device: Add support for PCIe Resizable BARsTim Wawrzynczak2022-02-161-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. BUG=b:214443809 TEST=compile (device with this capability not available yet), also verify that no changes are seen in resource allocation for google/brya0 before and after this change.

* device: Move MIPI panel library from mainboard/google/kukui into commonJulius Werner2021-08-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | 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. (Also, this will hopefully allow us to save some duplicated work when using the same panel on different boards at some point.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
