4255cc0a6b add SCC-related stuff to support the tickless kernel 2012-07-03 10:58:20 -07:00
Stefan Lankes
24914fcb4f add prototype of a tickless kernel 
only by entering the kernel, the tick counter will be updated
=> by using this feature, MetalSVM supports only LwIP's raw interface,
   because we have no guarantee that the tcpip thread will get computation time
=> no NETCONN & BSD socket support
=> no load balancing support

be4cfaf413 Merge remote-tracking branch 'origin/master' into x64_new 2012-06-10 08:07:50 +02:00

227cc19890 add alpha version of x64 support 
New features:
- support of kernel tasks in 64bit mode
- support of LwIP in 64bit mode

Missing features in 64bit mode
- user-level support
- APIC support => SMP support

To create a 64bit version of the MetalSVM kernel, the compiler flags “-m64 -mno-red-zone” and the assembler flags “-felf64” has to be used. Please use qemu-system-x86_64 as test platform.

Notice, metalsvm.elf is a 32bit ELF file. However, it contains (beside the startup code) only 64bit code. This is required because GRUB doesn’t boot 64bit ELF kernels. Therefore, for disassembling via objdump the flag  “-M x86-64” has to be used.

5a70cbbd75 Make it easier to change the number of used cores 
This commit uses the CORENUM Makefile variable to
generate scc_bootinfo.asm. This enables easier use of
more than one core.

0a577b9f7e Fixed the pageframe allocation error introduced by 
d641f5a211

wrote over it, it did affect the initrd...
