| | | | | | | | | | | | | | | | | | | This builds on the modular EFI loader support added r294060 adding a module to provide ZFS boot support on EFI systems. It should be noted that EFI uses a fixed size memory block for all allocations performed by the loader so it may be necessary to tune this size. For example when building an image which uses mfs_root e.g. mfsbsd, adding the following to /etc/make.conf would be needed to prevent EFI from running out of memory when loading the mfs_root image.

However, EFI uses the Windows ABI which does not support this. As a result, interrupt handlers in EFI push their interrupt frames directly on top of the stack pointer. If the compiler used the red zone in a function in the EFI loader, then a device interrupt that occurred while that function was running could trash its local variables. In practice this happens fairly reliable when using gzipfs as an interrupt during decompression can trash the local variables in the inflate_table() function resulting in corrupted output or hangs. Fix this by disabling the redzone for amd64 EFI binaries. This requires building not only the loader but any libraries used by the loader without redzone support. Thanks to Jilles for pointing me at the redzone once I found the stack corruption.

The process for booting from a CD under UEFI involves adding a FAT filesystem containing your loader code as an El Torito boot image. When UEFI detects this, it provides a block IO instance that points at the FAT filesystem as a child of the device that represents the CD itself. The problem being that the CD device is flagged as a "raw device" while the boot image is flagged as a "logical partition". The existing EFI partition code only looks for logical partitions and so the CD filesystem was rendered invisible. To fix this, check the type of each block IO device. If it's found to be a CD, and thus an El Torito boot image, look up its parent device and add that instead so that the loader will then load the kernel from the CD filesystem. This is done by using the handle for the boot filesystem as an alias. Something similar to this will be required for booting from other media as well as the loader will live in the EFI system partition, not on the partition containing the kernel. r247381: Remove a scatalogical debug printf that crept in.

| | | | | | | | | | | | | | | | | | | | | | | | Add support for Pre-Boot Virtual Memory (PBVM) to the loader. PBVM allows us to link the kernel at a fixed virtual address without having to make any assumptions about the physical memory layout. On the SGI Altix 350 for example, there's no usuable physical memory below 192GB. Also, the PBVM allows us to control better where we're going to physically load the kernel and its modules so that we can make sure we load the kernel in memory that's close to the BSP. The PBVM is managed by a simple page table. The minimum size of the page table is 4KB (EFI page size) and the maximum is currently set to 1MB. A page in the PBVM is 64KB, as that's the maximum alignment one can specify in a linker script. The bottom line is that PBVM is between 64KB and 8GB in size. The loader maps the PBVM page table at a fixed virtual address and using a single translations. The PBVM itself is also mapped using a single translation for a maximum of 32MB. While here, increase the heap in the EFI loader from 512KB to 2MB and set the stage for supporting relocatable modules.

| | | | | | | | | | | | | | | | | | | | | | | as this only allows us to access file systems that EFI knows about. With a loader that can only use EFI-supported file systems, we're forced to put /boot on the EFI system partition. This is suboptimal in the following ways: 1. With /boot a symlink to /efi/boot, mergemaster complains about the mismatch and there's no quick solution. 2. The EFI loader can only boot a single version of FreeBSD. There's no way to install multiple versions of FreeBSD and select one at the loader prompt. 3. ZFS maintains /boot/zfs/zpool.cache and with /boot a symlink we end up with the file on a MSDOS file system. ZFS does not have proper handling of file systems that are under Giant. Implement a disk device based on the block I/O protocol instead and pull in file system code from libstand. The disk devices are really the partitions that EFI knows about. This change is backward compatible. MFC after: 1 week
