Lluís Batlle i Rossell b1b7266aa3 After some testing with an ultrasparc cross-compiler: ... Updating the cross-build expressions, adding some flexibility. Updated the linux headers used cross building, as 2.6.28 had bugs on endianness in sparc64. There were, as usual some bugs in gcc. Maybe not many make a cross compiler to ultrasparc. For the record, I could build an ultrasparc kernel with this base nix: import /etc/nixos/nixpkgs/default.nix # The root nixpkgs default.nix { crossSystem = { config = "sparc64-unknown-linux"; bigEndian = true; arch = "sparc64"; float = "soft"; withTLS = true; cpu = "ultrasparc"; }; config = pkgs: { packageOverrides = pkgs : { platform = { name = "sparc64"; kernelHeadersBaseConfig = "sparc64_defconfig"; kernelBaseConfig = "sparc64_defconfig"; kernelArch = "sparc"; kernelAutoModules = false; kernelTarget = "zImage"; uboot = null; }; }; }; } Although it did not boot directly in qemu-system-sparc64: [sparc64] Kernel already loaded Unhandled Exception 0x0000000000000020 PC = 0x0000000000404000 NPC = 0x0000000000404004 svn path=/nixpkgs/trunk/; revision=20269		2010-02-27 00:52:48 +00:00
