When it comes to new features in an open source operating system, these features come from the community of developers who are contributors to a number of business companies. The latest FreeBSD 8.0 operating system has benefited from both contributions. Especially in the latest FreeBSD 8.0, Juniper (NYSE: JNPR) has contributed to the experimental MIPS support by the renowned network manufacturer. MIPS is a

We have recently established a cross-tool chain for the MIPs K processor: HOST: PC (32-bit) Virtual Machine: virtualbox Linux: CentOS-5.2 Target machine: Development Board with mips k Processor Linux version and package: linux-mti-2.6.35.9-2.tar.gz Cross tool chain: Mips-4.4-303-mips-linux-gnu-i686-pc-linux-gnu.tar.bz2

speed is generally not bad, the decompression will be completed soon, if the decompression is not completed in more than 5 minutes, it is strongly recommended to consider upgrading the machine or check the virtual machine configuration is not a problem, because the compilation is more time-consuming than the decompression of many times.

the page is missing from the virtual space where hugetlb is located, do_page_fault will add a flag to the last level-2 pmd entry, which is equivalent to telling the CPU that the pmd entry is the last level-1 page table. When page fault is returned and the CPU accesses the missing page address again, the CPU traverses the page table and does not unaddress the page when the page entry is found, for mips, since page table traversal and TLB refilling are

: * * * Linux_headers_site cannot is empty when Linux_headerbecause I could not find the corresponding header, I am here to compile kernel in buildroot2016.08 to 2.6 error. guess :the reason is because the corresponding kernel header could not be found. when you select a kernel in Toolchain, it is listed as part of the selection, or it can be selected manually. Guess, the list of parts is buildroot already included, and manual selection will need to go to download, probably via Linux channel (I

(1) If-OS-g is used at the same time, only-OS takes effect. (2) mips support delay slot, see: http://blog.csdn.net/dogsun88/article/details/7437178 For example: 854f8: 0320f809 jalr t9854fc: 02202021 move a0, s1 The last time the sub-function is called, the next sentence is to assign s1 to a0. In fact, before calling the sub-function, move a0 and s1 also take effect. If the-O0 method is used for compilation, the latency slot is not enabled. For examp

To add a system call, follow these steps:1. Add your system call entry to the system call table sys_call_table of the kernel. Select the file to be modified based on the number of kernel bits (32/64 bits:ARCH/MIPS/kernel/scall32-o32.S ------> 32bit KernelARCH/MIPS/kernel/scall64-64.S ------> 64bit Kernel 64bit kernel, if compatible with 32 bit Abi (o32, n32), you also need to modify scall64-o32.S or scall64

Cross-compilation tool for MIPS architecture Some MIPS-based set-top boxes provide six cross-compilation tools GCC, as follows:· Mipsel-Linux-gcc· Mipsel-Linux-uclibc-gcc· Mipsel-uclibc-gcc· MIPS-Linux-gcc· MIPS-Linux-uclibc-gcc· MIPS-uclibc-gcc What are the differences be

Explanation of the MIPS architecture Linux trojan for vromips Most Windows operating systems are installed on PCs of individual users, while Linux systems are widely used on servers. Therefore, Linux systems have fewer Trojans than Windows systems. Due to the application limitations of the MIPS architecture, Linux trojans on the MIPS architecture are rare. Recent

The MIPS architecture provides 32 GPR (general purpose register ). The usage of these 32 registers is roughly as follows: REGISTER NAME USAGE$0 $ zero constant 0 (constant value 0)$2-$3 $ v0-$ return value of v1 function call (values for results and
