* powerpc64le: stand fixesLeandro Lupori2021-10-201-3/+34
| | | | | | | | | | | | | | | | | | | | | | Fix boot1 and loader on PowerPC64 little-endian (LE). Due to endian issues, boot1 couldn't find the UFS boot partition and loader wasn't able to load the kernel. Most of the issues happened because boot1 and loader were BE binaries trying to access LE UFS partitions and because loader expects the kernel ELF image to use the same endian as itself. To fix these issues, boot1 and loader are now built as LE binaries on PPC64LE. To support this, the functions that call OpenFirmware were enhanced to correctly perform endian conversion on its input and output arguments and to change the CPU into BE mode before making the calls, as OpenFirmware always runs in BE. Besides that, some other small fixes were needed.

* powerpc64: fix loader regressionLeandro Lupori2021-09-211-11/+11
| | | | | | | | | | | | | | After b4cb3fe0e39a, loader started crashing on PowerPC64, with a Program Exception (700) error. The problem was that archsw was used before being initialized, with the new mount feature. This change fixes the issue by initializing archsw earlier, before setting currdev, that triggers the mount.

* stand/ficl 64-bit compatibilityBrandon Bergren2020-09-141-1/+1
| | | | | | | | | | | | | | | | | | | Currently, the only thing that prevents a functioning 64-bit FICL build is a few integer types that were intended to be fixed-width. Changing them to C99 integer types allows building a functioning 64-bit FICL. While this isn't applicable to the default settings of any in-tree loaders, it is necessary for a future Petitboot loader, due to the requirement that it be compiled as a 64-bit program.

* [PPC64] Implement CASLeandro Lupori2019-07-311-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Guest PPC OSs running under a hypervisor may communicate the features they support, in order for the hypervisor to expose a virtualized machine in the way the client (guest OS) expects (see LoPAPR 1.1 - B.6.2.3). This is done by calling the "/ibm,client-architecture-support" (CAS) method, informing supported features in option vectors. Until now, FreeBSD wasn't using CAS, but instead relied on hypervisor/QEMU's defaults. The problem is that, without CAS, it is very inconvenient to run POWER9 VMs on a POWER9 host running with radix enabled. This happens because, in this case, the QEMU default is to present the guest OS a dual MMU (HPT/RPT), instead of presenting a regular HPT MMU, as FreeBSD expects, resulting in an early panic. The known workarounds required either changing the host to disable radix or passing a flag to QEMU to run in a POWER8 compatible mode. With CAS, FreeBSD is now able to communicate that it wants an HPT MMU, independent of the host setup, which now makes FreeBSD work on POWER9/pseries, with KVM enabled and without hugepages (support added in a previous commit). As CAS is invoked through OpenFirmware's call-method interface, it needs to be performed early, when OpenFirmware is still operational. Besides, now that FDT is the default way to inspect the device tree on PPC, OFW call-method feature will be unavailable by default, when control is passed to the kernel. Because of this, the call to CAS is being performed at the loader, instead of at the kernel. To avoid regressions with old platforms, this change uses CAS only on POWER8/POWER9.

This feature is meant to be expanded until it is on by default unconditionally and, ideally, we can then garbage-collect the nightmare pile of hacks required to call into Open Firmware from a live kernel.
