2020-08-17soc/intel/skylake/acpi.c: Name devices on secondary busBenjamin Doron
Naming a device allows an ACPI _ROM method to be written for it. GPUs may require this to make the configuration data contained within available to an OS driver. This may be required for GPUs that do not contain their vBIOS, or perhaps the drivers require it in this form/fashion. Working on an Acer Aspire VN7-572G (Skylake-U). nouveau successfully obtains the vBIOS via ACPI (kernel 5.7.11).

2020-08-04soc/intel/skylake: Add RMRRs after all DRHDsAngel Pons
The VT-d architecture specification (Doc. D51397-011, Rev. 3.1) says: BIOS implementations must report these remapping structure types in numerical order. i.e., All remapping structures of type 0 (DRHD) enumerated before remapping structures of type 1 (RMRR), and so forth. So, update the corresponding code to adhere to the specification.

At runtime the final PRMRR size gets selected by checking the supported values in MSR_PRMRR_VALID_CONFIG and trying to select the value nearest to the chosen one.

2019-08-20src: Remove variable length arraysJacob Garber
Variable length arrays were a feature added in C99 that allows the length of an array to be determined at runtime. Eg. int sum(size_t n) { int arr[n]; ... } This adds a small amount of runtime overhead, but is also very dangerous, since it allows use of an unlimited amount of stack memory, potentially leading to stack overflow. This is only worsened in coreboot, which often has very little stack space to begin with. Citing concerns like this, all instances of VLA's were recently removed from the Linux kernel. In the immortal words of Linus Torvalds [0], AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and much _slower_ code (and more fragile code), than just using a fixed key size would have done. [...] Anyway, some of these are definitely easy to just fix, and using VLA's is actively bad not just for security worries, but simply because VLA's are a really horribly bad idea in general in the kernel. This patch follows suit and zaps all VLA's in coreboot. Some of the existing VLA's are accidental ones, and all but one can be replaced with small fixed-size buffers. The single tricky exception is in the SPI controller interface, which will require a rewrite of old drivers to remove [1].

To support generating USB devices in ACPI the platform needs to know how to determine a device name for each USB port, and for any root hubs that may be present. Recent Intel platforms route all ports to an XHCI controller through a root hub. This is supported by considering the root hub to be USB port type 0, the USB 2.0 ports to be type 2, and the USB 3.0 ports to be type 3. This was tested with a Kaby Lake platform by adding entries to the devicetree and checking the resulting SSDT.

Currently when enabling Deep S3 or Deep S5 it unconditionally gets enabled in both DC and AC states. However since using Deep S3 disables some expected features like wake-on-USB it is not always desired to enable the same state in both modes.
