Author: mcayland Date: Sat Oct 16 16:02:18 2010 New Revision: 896 URL: http://tracker.coreboot.org/trac/openbios/changeset/896 Log: Change OFMEM so that the generated available, physical and virtual properties are passed by reference into Forth. The previous code used the standard set_property() function which copies the new property into the dictionary each time the property is set. During OpenSolaris boot, this would cause OpenBIOS to run out of memory due to large number of changes to the memory regions. Now for each property we have a static buffer allocated within OpenBIOS which starts from 2K and doubles in size everytime the memory region is exhausted, and set the address directly to the relevant buffer. This saves a great deal of memory and prevents the dictionary and internal memory regions from being exhausted during OpenSolaris boot.

Hello Solaris :)

Hi everyone, For those of you interested in the progress of Solaris on OpenBIOS, I'm pleased to report the following output from SVN trunk (r886) with the attached patch applied (this is because the OpenSolaris 10 kernel seems to want quite a lot of run-time memory - more on this later): Solaris 9 installation CD: OpenBIOS for Sparc64 Configuration device id QEMU version 1 machine id 0 kernel cmdline CPUs: 1 x SUNW,UltraSPARC-IIi UUID: 00000000-0000-0000-0000-000000000000 Welcome to OpenBIOS v1.0 built on Oct 3 2010 20:40 Type 'help' for detailed information Trying cdrom:f...

A couple of things that will be of interest to other developers: - Solaris 9 seems to get stuck in a tight loop at the bottom of memory and doesn't want to proceed any further. - In order to get Milax to boot this far, I had to keep increasing the memory requirements (and as you can see, it still wants more). There is a lot of MMU mapping activity, and so I suspect most of the dictionary space is being used to update the translations properties. We really need to optimise OFMEM so that it doesn't keep allocating new space from the dictionary all the time which should help reduce this immensely. - Building with -O0 rather than -Os breaks Milax boot (the new SAVE_CPU_STATE handler falls over). This suggests that the stack is getting clobbered somewhere - Igor, any pointers on this one? But all in all, I think we're looking quite good :) ATB, Mark. -- Mark Cave-Ayland - Senior Technical Architect PostgreSQL - PostGIS Sirius Corporation plc - control through freedom http://www.siriusit.co.uk t: +44 870 608 0063 Sirius Labs: http://www.siriusit.co.uk/labs

Author: blueswirl Date: Sun Oct 3 21:18:28 2010 New Revision: 885 URL: http://tracker.coreboot.org/trac/openbios/changeset/885 Log: ppc: fix build with newer GCCs New GCCs (for example 4.6.0) needed a few more functions to libgcc. Without the functions, there were a lot of linker errors: LINK openbios-qemu.elf libqemu.a(ofmem.o): In function `hash_page': /src/openbios-devel/obj-ppc/../arch/ppc/qemu/ofmem.c:353: undefined reference to `_restgpr_25_x' libqemu.a(ofmem.o): In function `ea_to_phys': /src/openbios-devel/obj-ppc/../arch/ppc/qemu/ofmem.c:231: undefined reference to `_restgpr_30_x' etc. Copy the needed functions from Linux.
