The `IORESOURCE_ABOVE_4G` flag was only explicitly set for our dummy device that reserves resources behind a hotplug port. The current re- source allocator implicitly extends this to all devices below the port, including real ones. Let's make that explicit, so future changes to the allocator can't break this rule.

We have this quirk in our tree since the introduction of L1-substate support[1]. The way we searched for this capability was rather crude: We simply assumed that it would show up in the first data word of another capability.

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".

2022-02-10device: Add pciexp_find_next_extended_cap functionTim Wawrzynczak
Some PCIe devices have extended capability lists that contain multiples instances of the same capability. This patch provides a function similar to pciexp_find_extended_cap that can be used to search through multiple instances of the same capability by returning the offset of the next extended capability of the given type following the passed-in offset. The base functionality of searching for a given capability from an offset is extracted to a local helper function and both pciexp_find_extended_cap and pciexp_find_next_extended_cap use this helper.

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.

2020-10-21device: Allow virtual/generic devices under PCI in devicetreeDuncan Laurie
This change allows a generic device to be described in the devicetree under a PCI device, such as a root port. Previously any device under a PCI device was expected to also be a PCI device and that does not allow for a virtual/generic device to be present, for example to provide ACPI properties for a root port. The changes are: - Ignore non-PCI devices found under a PCI device when scanning and do not print an error for each devfn scanned. - Don't treat non-PCI devices as leftover and remove them, instead enable them as a static device. - Don't attempt to configure a static device in the tree that is not a PCIe device type. With these changes it is now possible to have a generic device under a PCI device, for example in a USB4/TBT root port (PCIe hotplug device) this generic device will add ACPI properties for the PCIe tunnel routed to the external port: device pci 07.0 on chip soc/intel/common/block/pcie device generic 0 on end end end TEST=boot on volteer with the USB4 root port devices in chipset.cb and ensure they are enabled properly and there are no errors printed in the coreboot log, and that the device properties are created in the SSDT.

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.

2017-12-08device/pciexp_device: Set values numerically instead of as bitmaskPatrick Georgi
As noted on linux-pci, we have a weird way to handling "value" and "scale" fields that are supposed to contain numerical values: we encode them as a bitfield. Instead define the two fields (offset and mask) and use numbers. Another issue, not fixed in this CL, is that we write hard-coded values while these fields really need to contain the max() of acceptable delays of the downstream devices. That way the controller can decide whether or not to enter a deeper power management state. It's noted as a TODO.

2016-12-01PCIEXP_PLUGIN_SUPPORT: Change dependency on PCI accessKyösti Mälkki
Some PCI-e capability registers are located starting from 0x100, these are not accessible using the conventional PCI IO config operations at 0xcf8/0xcfc, unless PCI_CFG_EXT_IO was selected. Thus any feature that calls pciexp_find_extended_cap() depends on either MMCONF_SUPPORT_DEFAULT or PCI_CFG_EXT_IO being enabled on the platform. In theory there can be system without MMCONF_SUPPORT, but with complete PCI Express configuration space available using PCI_CFG_EXT_IO. Do not use explicit PCI MMCONF operations here, but rely on the default PCI access method to be able to access all of the configuration space. While at it, convert to IS_ENABLED() everywhere in the source and organize Kconfig file better.
