[PATCH] cuda: fix len calculation in cuda_adb_req
by Amadeusz Sławiński 22 Sep '24

22 Sep '24

When advancing buffer by 1, len should be shorthened by appropriate amount, instead of setting it to -1. Found with cppcheck.

[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
