* MFaltix:Marcel Moolenaar2011-03-161-1/+1
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=219691

* Remove file system support based on the simple file system protocolMarcel Moolenaar2010-01-094-446/+268
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 Notes: svn path=/head/; revision=201941
* Enable GCC stack protection (aka Propolice) for userland:Ruslan Ermilov2008-06-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | - It is opt-out for now so as to give it maximum testing, but it may be turned opt-in for stable branches depending on the consensus. You can turn it off with WITHOUT_SSP. - WITHOUT_SSP was previously used to disable the build of GNU libssp. It is harmless to steal the knob as SSP symbols have been provided by libc for a long time, GNU libssp should not have been much used. - SSP is disabled in a few corners such as system bootstrap programs (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves. - It should be safe to use -fstack-protector-all to build world, however libc will be automatically downgraded to -fstack-protector because it breaks rtld otherwise. - This option is unavailable on ia64. Enable GCC stack protection (aka Propolice) for kernel: - It is opt-out for now so as to give it maximum testing. - Do not compile your kernel with -fstack-protector-all, it won't work.

* Major rework of the ia64 loaders. The two primary objectives are:Marcel Moolenaar2006-11-0514-1315/+527
| | | | | | | | | | | | | | | | | 1. Make libefi portable by removing ia64 specific code and build it on i386 and amd64 by default to prevent regressions. These changes include fixes and improvements over previous code to establish or improve APIs where none existed or when the amount of kluging was unacceptably high. 2. Increase the amount of sharing between the efi and ski loaders to improve maintainability of the loaders and simplify making changes to the loader-kernel handshaking in the future. The version of the efi and ski loaders are now both changed to 1.2 as user visible improvements and changes have been made. Notes: svn path=/head/; revision=164010

This change allows a future version of libefi to work without requiring anything more than what is defined in struct devdesc and as such makes it possible to compile said version of libefi for different platforms without requiring that those platforms have identical derivatives of struct devdesc.

This moves the dependency on GCC's and other compiler's features into the central sys/cdefs.h file, while the individual source files can then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42. By now, GCC and ICC (the Intel compiler) have been actively tested on IA32 platforms by netchild. Extension to other compilers is supposed to be possible, of course.

The fix is to rename .rela to .rela.dyn in the linker script so that all relocations end up in the same section again. This we copy into the EFI image. Notes: svn path=/head/; revision=132435

* Enable the i386 loader to load and run an amd64 kernel. If this putsPeter Wemm2003-05-011-3/+3
| | | | | | | | | | | | | | | | | | things over floppy size limits, I can exclude it for release builds or something like that. Most of the changes are to get the load_elf.c file into a seperate elf32_ or elf64_ namespace so that you can have two ELF loaders present at once. Note that for 64 bit kernels, it actually starts up the kernel already in 64 bit mode with paging enabled. This is really easy because we have a known minimum feature set. Of note is that for amd64, we have to pass in the bios int 15 0xe821 memory map because once in long mode, you absolutely cannot make VM86 calls. amd64 does not use 'struct bootinfo' at all. It is a pure loader metadata startup, just like sparc64 and powerpc. Much of the infrastructure to support this was adapted from sparc64. Notes: svn path=/head/; revision=114379

| | | | | | | | | | | | | | | | NULL is passed. The address of the HCDP table can be found by iterating over the configuration tables in the EFI system table. To avoid more duplication, a function can be called with the GUID of interest. The function will do the scanning. Use the function in all places where we iterate over the configuration tables in an attempt to find a specific one. Bump the loader version number as the result of this.
