The resulting - stream.dump file is the input file for h264_player. - - Note that it does not do any frame reordering, so the output is very - jittery. Also since it doesn't have access to the picinfo, it's - hardcoded to the right thing (so other videos are unlikely to play). - - (Current version commented s.t. it outputs just the first frame's - YUV data on stdout.) - -bsp_test: - - Tries to make sure that the BSP engine is accessible and functioning - properly. Invokes the 0x304 "write semaphore" method, and checks - whether the value is indeed written. - -decode_frame: - - Standalone program that decodes a single NAL (that it loads from a - separate file). This has all the bits necessary to do the actual - decoding, but uses hardcoded picinfo, as h264_player above. Output - is a YUV file on stdout. +extract_firmware +---------------- + +This tool is for older NVIDIA blob versions. These had netlist +archives embedded in them with gzip headers, and the video firmware +was raw data in the object file. + +The output of the tool is the video firmware, and optionally, the +extracted netlists classified by GPU (to potentially use in place of +the nouveau-made firmware). This classification is only done for very +specific versions. + +scanner +------- + +This is an explorational tool (written in Go!) to search for +compressed blobs inside of the blob object file. It uses relocation +data to locate potentially interesting bits of the rodata to search +through. The outputs are netlist archives, as well as "whole" +files. These tend to be falcon programs, but some are just data files. diff --git a/nouveau-firmware.spec b/nouveau-firmware.spec index 251415b..a494fdd 100644 --- a/nouveau-firmware.spec +++ b/nouveau-firmware.spec @@ -6,10 +6,10 @@ Summary: Firmware files used by the nouveau Linux kernel driver License: Redistributable, no modification permitted URL: https://nouveau.freedesktop.org/wiki/VideoAcceleration/ Source0: https://download.nvidia.com/XFree86/Linux-x86_64/%{version}/NVIDIA-Linux-... -Source1: https://raw.github.com/imirkin/re-vp2/master/extract_firmware.py -Source2: https://raw.github.com/imirkin/re-vp2/master/README +Source1: https://raw.githubusercontent.com/envytools/firmware/refs/heads/master/ex... +Source2: https://raw.githubusercontent.com/envytools/firmware/refs/heads/master/RE... -BuildRequires: python2-devel +BuildRequires: python3 BuildArch: noarch @@ -26,7 +26,7 @@ cp %{SOURCE2} . %build -%{__python2} %{SOURCE1} +%{__python3} %{SOURCE1} %install diff --git a/sources b/sources index aeddccc..0286bef 100644 --- a/sources +++ b/sources @@ -1,2 +1,2 @@ -7975d50a07d9cd9131dba60aef32a86f extract_firmware.py -ee9b52dcf9286c49fb23b6ca0d2b0e4a NVIDIA-Linux-x86_64-340.32.run +SHA512 (extract_firmware.py) = 1b3fbf2e09cd4cbd63d8f86fde88560e1be2e187abd086a8737e69d66a21fc33079be2ab161186f76f42e2e54881325528e425b1f6f350ea3c37222f4e0d1a47 +SHA512 (NVIDIA-Linux-x86_64-340.32.run) = 24c2dec161022bd229862ad66711232cf6424a0bd1eb056d7eb22a34e265d4b1f6208779cf507b480189f95f795d580a30ec5f8ab1bff549d2a41a57adcc14b4
