* On PowerPC send output to both "/chosen/stdout" and "screen" nodes, unlesssobomax2008-09-192-1/+30
| | | | | | | | | | | | | they point to the very same device. This should make loader usable on some (all?) PowerMacs, where "/chosen/stdout" is disconneted from the "screen" by the OF init process by default, except when user actually has requested interaction with OF by holding ALT-CMD-O-F. Along with rev 183168 this should provide a way to build bootable FreeBSD/ppc installation or live CD that works OOB. Also, it should bring PowerMac experience closer to that on other arches.

* Enable GCC stack protection (aka Propolice) for userland:ru2008-06-251-0/+3
| | | | | | | | | | | | | | | | | | | | | - 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.

* - Make better use of the global chosen, memory and mmu handles insteadmarius2007-06-177-281/+18
| | | | | | | | | | | | | | | | | | | | | | | | | of obtaining them over and over again and pretending we could do anything useful without them (for chosen this includes adding a declaration and initializing it in OF_init()). - In OF_init() if obtaining the memory or mmu handle fails just call OF_exit() instead of panic() as the loader hasn't initialized the console at these early stages yet and trying to print out something causes a hang. With OF_exit() one at least has a change to get back to the OFW boot monitor and debug the problem. - Fix OF_call_method() on 64-bit machines (this is a merge of sys/dev/ofw/openfirm.c rev 1.6). - Replace OF_alloc_phys(), OF_claim_virt(), OF_map_phys() and OF_release_phys() in the MI part of the loader with wrappers around OF_call_method() in the sparc64. Beside the fact that they duplicate OF_call_method() the formers should never have been in the MI part of the loader as contrary to the OFW spec they use two-cell physical addresses. - Remove unused functions which are also MD dupes of OF_call_method(). - In sys/boot/sparc64/loader/main.c add __func__ to panic strings as different functions use otherwise identical panic strings and make some of the panic strings a tad more user-friendly instead of just mentioning the name of the function that returned an unexpected result.

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 was creating far too many single-page mappings, and eventually OFW overflowed some internal data structure and refused to map any more. The new algorithm creates far less mappings and fixed a bug where multiple mappings for the same page would be created. 'Twas known this was a problem, but only became urgent when the install CD's mfs_root grew large enough to cause the overflow.

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