* Use the new arch_loadaddr I/F to align ELF objects to PBVM pagemarcel2011-04-033-47/+127
| | | | | | | | | | | | | | | | | | boundaries. For good measure, align all other objects to cache lines boundaries. Use the new arch_loadseg I/F to keep track of kernel text and data so that we can wire as much of it as is possible. It is the responsibility of the kernel to link critical (read IVT related) code and data at the front of the respective segment so that it's covered by TRs before the kernel has a chance to add more translations. Use a better way of determining whether we're loading a legacy kernel or not. We can't check for the presence of the PBVM page table, because we may have unloaded that kernel and loaded an older (legacy) kernel after that. Simply use the latest load address for it.
* MFaltix:marcel2011-03-164-52/+250
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Enable GCC stack protection (aka Propolice) for userland:ru2008-06-251-0/+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.

* Have the processor defer all faults and exceptions for controlmarcel2007-05-271-1/+1

* Major rework of the ia64 loaders. The two primary objectives are:marcel2006-11-057-499/+483
| | | | | | | | | | | | | | 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.
* Extend struct devdesc with a unit field, called d_unit. Promote themarcel2006-11-021-4/+4
| | | | | | | | | device (kind) specific unit field to the common field. 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.

| | | | | | | | | | | | | | | 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.

* Pass the HCDP table address to the kernel. If no such table exists,marcel2002-12-101-0/+3
| | | | | | | | | | | | | 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. Approved by: re (blanket)
* Remove a left-over virtual mapping of uncached I/O port space.marcel2002-11-281-17/+0
| | | | | | | | | | | | | Previous kernels unwantingly depended on this mapping, but as of version 1.123 of src/sys/ia64/ia64/machdep.c this dependency has been removed. Consequently, one has to update the kernel before updating the loader. The documented/recommended upgrade will suffice in this case. Due to a visible (from the kernels point of view) change in behaviour, bump the loader version number from 0.3 to 1.0. Approved by: re (carte blanc)
* o Fix a size calculation based on a 8KB page, while under EFImarcel2002-10-242-16/+35
| | | | | | | | | | | | pages are 4KB. o As a second order fix, don't assume we have enough space after the bootinfo block left in a page to hold the memory map. o A third order fix as that we removed the assumption that a bootinfo block fits in a single 8KB page.

It is expected that future kernels use register r8 to get to the bootinfo block and don't depend on the hardwired address anymore. Bump the loader version once again due to the interface change.
