[PATCH 0/6] Fixes for Forth PCI config access words and implementation
by Mark Cave-Ayland 30 Jul '24

30 Jul '24

This series provides a set of fixes required to allow Forth PCI config access words to work correctly on both 32-bit and 64-bit platforms, along with Zoltan's original v4 patch. There are 2 main fixes included: - Implement and convert PCI encode-unit/decode-unit to static methods - Fix my-address and my-unit on 64-bit platforms With this series applied it is possible to execute the Forth PCI config words as documented in various drivers as below: PPC (32-bit): 0 > showstack ok 0 > " /pci/QEMU,VGA" open-dev to my-self ok 0 > my-space " config-w@" $call-parent u. 1234 ok 0 > my-space ok 800 < 1 > my-address ok 800 0 0 < 3 > SPARC64 (64-bit, including across PCI bridge): 0 > showstack ok 0 > " /pci/pci@1,1/QEMU,VGA" open-dev to my-self ok 0 > my-space " config-w@" $call-parent u. 1234 ok 0 > my-space ok 11000 < 1 > my-address ok 11000 0 0 < 3 > Signed-off-by: Mark Cave-Ayland <mark.cave-ayland(a)ilande.co.uk> BALATON Zoltan (1): drivers/pci: Implement config access words Mark Cave-Ayland (5): libopenbios/clib.fs: add new is-2arg-cfunc for calling into C libopenbios: introduce BIND_NODE_STATIC_METHOD and supporting functions drivers/pci.c: convert encode-unit and decode-unit words to static methods package.fs: fix my-address on 64-bit systems package.fs: fix my-unit on 64-bit systems drivers/pci.c | 115 +++++++++++++++++++++++++++++++-- forth/device/package.fs | 8 +-- include/libopenbios/bindings.h | 7 ++ libopenbios/bindings.c | 26 ++++++++ libopenbios/clib.fs | 10 +++ 5 files changed, 155 insertions(+), 11 deletions(-) -- 2.30.2

GRUB causes Unhandled Exception in firmware for sparc64 build
by Glenn Washburn 01 Aug '23

Hi all, I've been running into an issue with a GRUB test where it is causing an Unhandled Exception from within the openbios sparc64 firmware. I've created an issue[1] on github mainly to store the reproducing ISO. I'm not sure what the root issue is, but it seems to have something to do with having the firmware open the floppy drive. This happens on a build from master, the latest release build, and an old build packaged with Debian. None of the other GRUB tests trigger this bug. Any ideas what's going on?
