This adds SPDX-License-Identifiers to all of the files in src/include that are missing them or have unrecognized identifiers.

Files that were sourced from Linux are similarly GPL-2.0-only.

2022-02-10Revert "cpu/x86/lapic: Unconditionally use CPUID leaf 0xb if available"Felix Held
This reverts commit ceaf959678905f44a54a116f37bd15acab5d4608. The AMD Picasso SoC doesn't support x2APIC and neither advertises the presence of its support via bit 21 in EAX of CPUID leaf 1 nor has the bit 10 in the APIC base address MSR 0x1b set, but it does have 0xd CPUID leaves, so just checking for the presence of that CPUID leaf isn't sufficient to be sure that EDX of the CPUID leaf 0xb will contain a valid APIC ID. In the case of Picasso EDX of the CPUID leaf 0xb returns 0 for all cores which causes coreboot to get stuck somewhere at the end of MP init. I'm not 100% sure if we should additionally check bit 21 in EAX of CPUID function 1 is set instead of adding back the is_x2apic_mode check. TEST=Mandolin with a Picasso SoC boots again.

In PARALLEL_MP case enable_lapic() was redundant as it was already executed prior to initialize_cpu() call. For the !PARALLEL_MP case enable_lapic() is added to AP CPUs.

Allows compile-time optimisation on platforms that do not wish to enable runtime checking of X2APIC. Legacy lapic_cpu_init() is incompatible so there is dependency on PARALLEL_MP. Also stop_this_cpu() is incompatible, so there is dependency on !AP_IN_SIPI_WAIT. Since the code actually lacks enablement of X2APIC (apparently assuming the blob has done it) and the other small flaws pointed out in earlier reviews, X2APIC_RUNTIME is not selected per default on any platform yet.

This reverts commit 042c1461fb777e583e5de48edf9326e47ee5595f. It turned out that sending IPIs via broadcast doesn't work on Sandybridge. We tried to come up with a solution, but didn't found any so far. So revert the code for now until we have a working solution.

2012-07-02Use broadcast SIPI to startup siblingsSven Schnelle
The current code for initializing AP cpus has several shortcomings: - it assumes APIC IDs are sequential - it uses only the BSP for determining the AP count, which is bad if there's more than one physical CPU, and CPUs are of different type Note that the new code call cpu->ops->init() in parallel, and therefore some CPU code needs to be changed to address that. One example are old Intel HT enabled CPUs which can't do microcode update in parallel.

2007-12-19Changed the stop_this_cpu() to just hlt.Marc Jones
Removed local APIC INIT (don't worry the APIC and AP are still initialized). The local APIC INIT seemed to be the incorrect thing to do to stop an AP. The Intel Multiprocessor specification indicated that a vector should be set and a START should happen following an INIT. Then AP will execute the instructions pointed to by the vector. There is no vector or start in stop_this_cpu(). This seems to put the AP in an in-between state. In the case of Barcelona the AP's MSRs and PCI register are not accessible by the hardware debugger. The better solution seems to be to just put the AP in a hlt and allow the AP to go into C1. Then APIC managing software running on the BSP can program the AP as needed.
