* amd64 loader: Use efiserialio for Hyper-V booted systemsWei Hu6 days1-0/+1
| | | | | | | | | | | | | | | | | | | | | | | UEFI provides ConIn/ConOut handles for consoles that it supports, which include the text-video and serial ports. When the serial port is available, use the UEFI driver instead of direct io-port accesses to avoid conflicts between the firmware and direct hardware access, as happens on Hyper-V (Azure) setups. This change enables efiserialio to be built for efi-amd64 and has higher order priority vs comconsole, and only uses efiserialio if the hypervisor is Hyper-V. When efiserialio successfully probes, it will set efi_comconsole_avail=true which will prevent comconsole from probing in this setup. Tested on Hyper-V, ESXi and Azure VMs. PR: 264267 Reviewed by: kevans, whu Tested by: whu Obtained from: Rubicon Communications, LLC (Netgate) MFC after: 2 weeks Sponsored by: Rubicon Communications, LLC (Netgate)

| | | | | | | | | | | Given that hints set this way don't work when a static kenv is compiled into the kernel. acpi.rsdp has been set for this for the past 6 years, and all kernels in that time have used it in preference to the hints.

* amd64 UEFI loader: stop copying staging area to 2M physicalKonstantin Belousov2021-08-081-28/+114
| | | | | | | | | | | | | | | | | | | | | On amd64, add a possibility to activate kernel with staging area in place. Add 'copy_staging' command to control this. For now, by default the old mode of copying kernel to 2M phys is retained. It is going to be changed in several weeks. On amd64, add some slop to the staging area to satisfy both requirements of the kernel startup allocator, and to have space for minor staging data increase after the final size is calculated. Add a new command 'staging_slop' to control its size. Improve staging area resizing, in particular, reallocate it anew if we cannot grow it neither down nor up.

* stand/multiboot2: add support for booting a Xen dom0 in UEFI modeRoger Pau Monné2021-02-165-0/+1001
| | | | | | | | | | | | | | | | | | | | Add some basic multiboot2 infrastructure to the EFI loader in order to be capable of booting a FreeBSD/Xen dom0 when booted from UEFI. Only a very limited subset of the multiboot2 protocol is implemented in order to support enough to boot into Xen, the implementation doesn't intend to be a full multiboot2 capable implementation. Such multiboot2 functionality is hooked up into the amd64 EFI loader, which is the only architecture that supports Xen dom0 on FreeBSD. The options to boot a FreeBSD/Xen dom0 system are exactly the same as on BIOS, and requires setting the xen_kernel and xen_cmdline options in loader.conf.

* stand/efi: allow not exiting boot servicesRoger Pau Monné2021-02-165-10/+13
| | | | | | | | | | | | | | | | | | Xen requires that UEFI BootServices are enabled in order to boot, so introduce a new parameter to bi_load in order to select whether BS should be exited. No functional change introduced in this patch, as all current users of bi_load request BS to be exited. Further changes will make use of this functionality. Note the memory map is still appended to the kernel metadata, even when it could be modified by further calls to the Boot Services, as it will be used to detect if the kernel has been booted from UEFI.

* Use adrp in the arm64 efi loaderAndrew Turner2020-10-131-5/+10
| | | | | | | | | | | | | | | | | On startup the arm64 efi loaders need to know PC-relative addresses. Previously we used the adr instruction to find this address, however this instruction is limited to +/- 1MiB. Switch to adrp to find the 4k page the address is within and an add to set the bottom 12 bits. This lets us address +/- 4GiB which should be large enough for now.

| | | | | | | | | | | | | | | | | | | | | This implementation doesn't have any major deviations from the other EFI ports. I've copied the boilerplate from arm and arm64. I've tested this with the following boot flows: OpenSBI (M-mode) -> u-boot (S-mode) -> loader.efi -> FreeBSD OpenSBI (M-mode) -> u-boot (S-mode) -> boot1.efi -> loader.efi -> FreeBSD Due to the way that u-boot handles secondary CPUs, OpenSBI >= v0.7 is required, as the HSM extension is needed to bring them up explicitly. Because of this, using BBL as the SBI implementation will not be possible. Additionally, there are a few recent u-boot changes that are required as well, all of which will be present in the upcoming v2020.07 release.

* veloader use vectx API for kernel and modulesSimon J. Gerraty2020-03-081-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vectx API, computes the hash for verifying a file as it is read. This avoids the overhead of reading files twice - once to verify, then again to load. For doing an install via loader, avoiding the need to rewind large files is critical. This API is only used for modules, kernel and mdimage as these are the biggest files read by the loader. The reduction in boot time depends on how expensive the I/O is on any given platform. On a fast VM we see 6% improvement. For install via loader the first file to be verified is likely to be the kernel, so some of the prep work (finding manifest etc) done by verify_file() needs to be factored so it can be reused for vectx_open(). For missing or unrecognized fingerprint entries, we fail in vectx_open() unless verifying is disabled. Otherwise fingerprint check happens in vectx_close() and since this API is only used for files which must be verified (VE_MUST) we panic if we get an incorrect hash.

| | | | | | | | | | | | | | | | | | r328169 removed the copy of bootinfo that would've made this somewhat functional. However, this is irrelevant- earlier work in r292338 was done to exit boot services in the MI bi_load() rather than having N copies of the GetMemoryMap/ExitBootServices dance. i386 never quite caught up to that; ldr_enter was still being called but the prereq for that, ldr_bootinfo, was no longer. As a consequence, this ExitBootServices() was being called with a mapkey=0, clearly bogus, and reportedly breaking the boot in some instances.

* Ensure we have a large enough stack for the lua loaderAndrew Turner2018-08-271-0/+17
| | | | | | | | | | | | | | | | | | | Lua has a few places where it allocates a large buffer on the stack. This is normally fine, except there are a few places where there can be multiple frames with this buffer. This can cause a stack overflow on some arm64 SoCs. Fix this by allocating our own stack in loader.efi large enough for these objects. The required size has been found by tracing how the stack pointer changes in a virtual machine and found to be no larger than 50kB. A larger stack is allocated to reduce the likelihood of overflow from future changes.
