v1.31 - 19990212 Zoltán Böszörményi <zboszor@mail.externet.hu> - Major rewrite of cyrix_arr_init(): do not touch ARRs, - leave them as the BIOS have set them up. - Enable usage of all 8 ARRs. - Avoid multiplications by 3 everywhere and other - code clean ups/speed ups. - 19990213 Zoltán Böszörményi <zboszor@mail.externet.hu> - Set up other Cyrix processors identical to the boot cpu. - Since Cyrix don't support Intel APIC, this is l'art pour l'art. - Weigh ARRs by size: - If size <= 32M is given, set up ARR# we were given. - If size > 32M is given, set up ARR7 only if it is free, - fail otherwise. - 19990214 Zoltán Böszörményi <zboszor@mail.externet.hu> - Also check for size >= 256K if we are to set up ARR7, - mtrr_add() returns the value it gets from set_mtrr() - 19990218 Zoltán Böszörményi <zboszor@mail.externet.hu> - Remove Cyrix "coma bug" workaround from here. - Moved to linux/arch/i386/kernel/setup.c and - linux/include/asm-i386/bugs.h - 19990228 Richard Gooch <rgooch@atnf.csiro.au> - Added MTRRIOC_KILL_ENTRY ioctl(2) - Trap for counter underflow in <mtrr_file_del>. -

v1.32 - 19990308 Zoltán Böszörményi <zboszor@mail.externet.hu> - Adjust my changes (19990212-19990218) to Richard Gooch's - latest changes. (19990228-19990305) - v1.33 - 19990309 Richard Gooch <rgooch@atnf.csiro.au> - Fixed typo in <printk> message. - 19990310 Richard Gooch <rgooch@atnf.csiro.au> - Support K6-II/III based on Alan Cox's <alan@redhat.com> patches. - v1.34 - 19990511 Bart Hartgers <bart@etpmod.phys.tue.nl> - Support Centaur C6 MCR's. - 19990512 Richard Gooch <rgooch@atnf.csiro.au> - Minor cleanups. - v1.35 - 19990707 Zoltán Böszörményi <zboszor@mail.externet.hu> - Check whether ARR3 is protected in cyrix_get_free_region() - and mtrr_del(). The code won't attempt to delete or change it - from now on if the BIOS protected ARR3. It silently skips ARR3 - in cyrix_get_free_region() or returns with an error code from - mtrr_del(). - 19990711 Zoltán Böszörményi <zboszor@mail.externet.hu> - Reset some bits in the CCRs in cyrix_arr_init() to disable SMM - if ARR3 isn't protected. This is needed because if SMM is active - and ARR3 isn't protected then deleting and setting ARR3 again - may lock up the processor. With SMM entirely disabled, it does - not happen. - 19990812 Zoltán Böszörményi <zboszor@mail.externet.hu> - Rearrange switch() statements so the driver accomodates to - the fact that the AMD Athlon handles its MTRRs the same way - as Intel does. - 19990814 Zoltán Böszörményi <zboszor@mail.externet.hu> - Double check for Intel in mtrr_add()'s big switch() because - that revision check is only valid for Intel CPUs. - 19990819 Alan Cox <alan@redhat.com> - Tested Zoltan's changes on a pre production Athlon - 100% - success. - 19991008 Manfred Spraul <manfreds@colorfullife.com> - replaced spin_lock_reschedule() with a normal semaphore. - v1.36 - 20000221 Richard Gooch <rgooch@atnf.csiro.au> - Compile fix if procfs and devfs not enabled. - Formatting changes. - v1.37 - 20001109 H. Peter Anvin <hpa@zytor.com> - Use the new centralized CPU feature detects. - - v1.38 - 20010309 Dave Jones <davej@suse.de> - Add support for Cyrix III. - - v1.39 - 20010312 Dave Jones <davej@suse.de> - Ugh, I broke AMD support. - Reworked fix by Troels Walsted Hansen <troels@thule.no> - - v1.40 - 20010327 Dave Jones <davej@suse.de> - Adapted Cyrix III support to include VIA C3. - - v2.0 - 20020306 Patrick Mochel <mochel@osdl.org> - Split mtrr.c -> mtrr/*.c - Converted to Linux Kernel Coding Style - Fixed several minor nits in form - Moved some SMP-only functions out, so they can be used - for power management in the future. - TODO: Fix user interface cruft. |
