2020-05-20device/pci_device: Add notion of "hidden" PCI devicesTim Wawrzynczak
On some SoCs, there are PCI devices that may get hidden from PCI enumeration by platform firmware. Because the Vendor ID reads back as 0xffffffff, it appears that there is no PCI device located at that BDF. However, because the device does exist, designers may wish to hang its PCI resources off of a real __pci_driver, as well as have it participate in ACPI table generation. This patch extends the semantics of the 'hidden' keyword in devicetree.cb. If a device now uses 'hidden' instead of 'on', then it will be assumed during PCI enumeration that the device indeed does exist, and it will not be removed as a "leftover device." This allows child devices to be enumerated correctly and also PCI resources can be designated from the {read,set}_resources callbacks. It should be noted that as of this commit, there are precisely 0 devices using 'hidden' in their devicetree.cb files, so this should be a safe thing to do. Later patches will begin moving PCI resources from random places (typically hung off of fixed SA and LPC) into the PMC device (procedure will vary per- platform).

2020-05-12device: Enable resource allocation above 4G boundaryFurquan Shaikh
This change adds support for allocating resources above the 4G boundary by making use of memranges for resource windows enabled in the previous CL. It adds a new resource flag IORESOURCE_ABOVE_4G which is used in the following ways: a) Downstream device resources can set this flag to indicate that they would like to have their resource allocation above the 4G boundary. These semantics will have to be enabled in the drivers managing the devices. It can also be extended to be enabled via devicetree. This flag is automatically propagated by the resource allocator from downstream devices to the upstream bridges in pass 1. It is done to ensure that the resource allocator has a global view of downstream requirements during pass 2 at domain level. b) Bridges have a single resource window for each of mem and prefmem resource types. Thus, if any downstream resource of the bridge requests allocation above 4G boundary, all the other downstream resources of the same type under the bridge will be allocated above 4G boundary. c) During pass 2, resource allocator at domain level splits IORESOURCE_MEM into two different memory ranges -- one for the window below 4G and other above 4G. Resource allocation happens separately for each of these windows. d) At the bridge level, there is no extra logic required since the resource will live entirely above or below the 4G boundary. Hence, all downstream devices of any bridge will fall within the window allocated to the bridge resource. To handle this case separately from that of domain, initializing of memranges for a bridge is done differently than the domain. Limitation: Resources of a given type at the bridge or downstream devices cannot live both above and below 4G boundary. Thus, if a bridge has some downstream resources requesting allocation for a given type above 4G boundary and other resources of the same type requesting allocation below 4G boundary, then all these resources of the same type get allocated above 4G boundary. BUG=b:149186922 TEST=Verified that resources get allocated above the 4G boundary correctly on volteer.

2020-05-12device: Enable resource allocator to use multiple rangesFurquan Shaikh
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. BUG=b:149186922 TEST=Verified that resource allocation looks correct based on addresses assigned on Volteer.

2020-02-08Add configurable ramstage support for minimal PCI scanningRonald G. Minnich
This CL has changes that allow us to enable a configurable ramstage, and one change that allows us to minimize PCI scanning. Minimal scanning is a frequently requested feature. To enable it, we add two new variables to src/Kconfig CONFIGURABLE_RAMSTAGE is the overall variable controlling other options for minimizing the ramstage. MINIMAL_PCI_SCANNING is how we indicate we wish to enable minimal PCI scanning. Some devices must be scanned in all cases, such as 0:0.0. To indicate which devices we must scan, we add a new mandatory keyword to sconfig It is used in place of on, off, or hidden, and indicates a device is enabled and mandatory. Mandatory devices are always scanned. When MINIMAL_PCI_SCANNING is enabled, ONLY mandatory devices are scanned. We further add support in src/device/pci_device.c to manage both MINIMAL_PCI_SCANNING and mandatory devices. Finally, to show how this works in practice, we add mandatory keywords to 3 devices on the qemu-q35. TEST= 1. This is tested and working on the qemu-q35 target. 2.

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.

2019-12-11printf: Automatically prefix %p with 0xJulius Werner
According to the POSIX standard, %p is supposed to print a pointer "as if by %#x", meaning the "0x" prefix should automatically be prepended. All other implementations out there (glibc, Linux, even libpayload) do this, so we should make coreboot match. This patch changes vtxprintf() accordingly and removes any explicit instances of "0x%p" from existing format strings. How to handle zero padding is less clear: the official POSIX definition above technically says there should be no automatic zero padding, but in practice most other implementations seem to do it and I assume most programmers would prefer it. The way chosen here is to always zero-pad to 32 bits, even on a 64-bit system. The rationale for this is that even on 64-bit systems, coreboot always avoids using any memory above 4GB for itself, so in practice all pointers should fit in that range and padding everything to 64 bits would just hurt readability. Padding it this way also helps pointers that do exceed 4GB (e.g. prints from MMU config on some arm64 systems) stand out better from the others.

2019-10-06device/pci: Enable full 16-bit VGA port i/o decodingNico Huber
So, the PCI to PCI bridge specification had a pitfall for us: Originally, when decoding i/o ports for legacy VGA cycles, bridges should only consider the 10 least significant bits of the port address. This means all VGA registers were aliased every 1024 ports! e.g. 0x3b0 was also decoded as 0x7b0, 0xbb0 etc. However, it seems, we never reserved the aliased ports, resulting in silent conflicts we preallocated resources. We neither use much external VGA nor many i/o ports these days, so nobody noticed. To avoid this mess, a bridge control bit (VGA16) was introduced in 2003 to enable decoding of 16-bit port addresses. As older systems seem rather safe and well tested, and newer systems should support this bit, we'll use it if possible and only warn if not. With old (AGP era) hardware one will likely encounter a warning like this: found VGA at PCI: 06:00.0 A bridge on the path doesn't support 16-bit VGA decoding! This is not generally fatal, but makes unnoticed resource conflicts more likely.

2019-09-15lib/coreboot_table: Show splashscreen in lb_table_initJohanna Schander
Every vga init implementation needs to cache the framebuffer state to be able to fill the lb_framebuffer struct later on in the fill_lb_framebuffer call. 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. This can be overwriten by configuration by setting CONFIG_DRIVERS_EMULATION_QEMU_BOCHS_{X,Y}RES .

2019-08-22Add buffer_to/from_fifo32(_prefix) helpersJulius Werner
Many peripheral drivers across different SoCs regularly face the same task of piping a transfer buffer into (or reading it out of) a 32-bit FIFO register. Sometimes it's just one register, sometimes a whole array of registers. Sometimes you actually transfer 4 bytes per register read/write, sometimes only 2 (or even 1). Sometimes writes need to be prefixed with one or two command bytes which makes the actual payload buffer "misaligned" in relation to the FIFO and requires a bunch of tricky bit packing logic to get right. Most of the times transfer lengths are not guaranteed to be divisible by 4, which also requires a bunch of logic to treat the potential unaligned end of the transfer correctly. We have a dozen different implementations of this same pattern across coreboot. This patch introduces a new family of helper functions that aims to solve all these use cases once and for all (*fingers crossed*).

2019-07-26src/device/oprom: Fix bootsplash display code for optionromsJohanna Schander
So far the bootsplash is only correctly rendered if the framebuffer is set up as 1024x768@16. Different resolutions did not show anything, differnent depth resulted in the distorted images. This commit removes this limit by using the actual framebuffer resolutions and combines the code for x86 and yabel. For the moment the bootsplash is still limited to VGA-OptionROM framebuffer init. It was tested in 1280x1024@32 on the wip razer blade stealth using the intel vgabios.
