* Part 1 of fixing the boot code: binutils 2.15 fixes.Marcel Moolenaar2004-08-222-1/+202
| | | | | | | | | | | | | | | The binutils 2.15 assembler now automaticly and non-optionally adds the .eh_frame section for unwind information. This section appears to wreck havoc to the final boot code. Fix this by using a special linker script that discards the .eh_frame sections, but is otherwise identical to the linker internal script used for -N. Compiler used: gcc 3.3.5 Verified with: binutils 2.14 & binutils 2.15 (stock and in-tree) Tested with: /boot/loader & /boot/netboot Notes: svn path=/head/; revision=134140

* Work around what looks like a bad make(1) bug. For some reason,Peter Wemm2001-06-161-5/+3
| | | | | | | | | | | | | | | | | | | | | make(1) wants to build loader.sym *before* the .o files. Eliminating one seeminly intermediate step avoids the problem. Somehow, it seems that variables are not getting expanded at the right time. Any explanations would be appreciated... Changing: ${BASE}.sym: ${OBJS} ${LIBSTAND} ${LIBFICL} ${LIBALPHA} ${CRT} vers.o ${LD} ... To: BASEOBJS= ${OBJS} ${LIBSTAND} ${LIBFICL} ${LIBALPHA} ${CRT} vers.o ${BASE}.sym: ${BASEOBJS} echo ${BASEOBJS} ${LD} ... .. the echo only shows LIBFICL, CRT and vers.o. ${OBJS} is not included.

* Move the call to extend_heap() from main to start so that if our BSSDoug Rabson2000-10-251-3/+2

* Always install loader.4th, defaults/loader.conf, and support.4th instead ofJohn Baldwin2000-07-101-1/+1
| | | | | | | | | | only doing so if loader.rc does not exist. This fixes the problem where installworld doesn't update /boot/loader.4th, resulting in device.hints not being loaded after updating past the config(8) changes, which resulted in mcclock0 not being probed, and a nice kernel panic during boot.

* Implement a simple LRU block cache. By default this is initialised to 16k,Mike Smith1998-11-021-1/+6
| | | | | | | | | | | | | | | | | and will bypass transfers for more than 8k. Blocks are invalidated after 2 seconds, so removable media should not confuse the cache. The 8k threshold is a compromise; all UFS transfers performed by libstand are 8k or less, so large file reads thrash the cache. However many filesystem metadata operations are also performed using 8k blocks, so using a lower threshold gives poor performance. Those of you with an eye for cache algorithms are welcome to tell me how badly this one sucks; you can start with the 'bcachestats' command which will print the contents of the cache and access statistics.

* Initial integration of the i386 bootloader and BTX.Mike Smith1998-09-171-313/+0
| | | | | | | | | | | | | | - Discard large amounts of BIOS-related code in favour of the more compact BTX vm86 interface. - Build the loader module as ELF, although the resulting object is a.out, make gensetdefs 32/64-bit sensitive and use a single copy of it. - Throw away installboot, as it's no longer required. - Use direct bcopy operations in the i386_copy module, as BTX maps the first 16M of memory. Check operations against the detected size of actual memory. Notes: svn path=/head/; revision=39441
* Bootstrap updates.Mike Smith1998-09-031-10/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Move some startup code from MD to MI sections - Add a 'copyout' and some copyout-related functions. These will be obsoleted when BTX is available for the 386 and the kernel load area becomes directly addressable. - Add the ability load an arbitrary file as a module, associating and arbitrary type string with it. This can be used eg. for loading splash-screen images etc. - Add KLD module dependancy infrastructure. We know how to look for dependancies inside KLD modules, how to resolve these dependancies and what to do if things go wrong. Only works for a.out at the moment, due to lack of an MI ELF loader. Attach KLD module information to loaded modules as metadata, but don't pass it to the kernel (it can find it itself). - Load a.out KLD modules on a page boundary. Only pad the a.out BSS for the kernel, as it may want to throw symbols away. (We might want to do this for KLD modules too.) - Allow commands to be hidden from the '?' display, to avoid cluttering it with things like 'echo'. Add 'echo'. - Bring the 'prompt' command into line with the parser syntax. - Fix the verbose 'ls'; it was using an uninitialised stack variable. - Add a '-v' flag to 'lsmod' to have it display module metadata as well (not terribly useful for the average user) - Support a 'module searchpath' for required modules. - The bootstrap file on i386 is now called 'loader' to permit the /boot directory to use that name. - Discard the old i386 pread() function, as it's replaced by arch_readin() Notes: svn path=/head/; revision=38764
* Bootloader update.Mike Smith1998-08-311-2/+3
| | | | | | | | | | | | | | | - Implement a new copyin/readin interface for loading modules. This allows the module loaders to become MI, reducing code duplication. - Simplify the search for an image activator for the loaded kernel. - Use the common module management code for all module metadata. - Add an 'unload' command that throws everything away. - Move the a.out module loader to MI code, add support for a.out kld modules.

* Minor tweaks to track a couple of i386 changes and to make it compile.Doug Rabson1998-08-221-4/+17
| | | | Notes: svn path=/head/; revision=38475
* This is the new unified bootstrap, sometimes known previously as theMike Smith1998-08-214-0/+581
'three-stage' bootstrap. There are a number of caveats with the code in its current state: - The i386 bootstrap only supports booting from a floppy. - The kernel and kld do not yet know how to deal with the extended information and module summary passed in. - PnP-based autodetection and demand loading of modules is not implemented. - i386 ELF kernel loading is not ready yet. - The i386 bootstrap is loaded via an ugly blockmap. On the alpha, both net- and disk-booting (SRM console machines only) is supported. No blockmaps are used by this code. Obtained from: Parts from the NetBSD/i386 standalone bootstrap.
