Android-X68 4.3 without SSE-2 or SSE-3

[Eric Kehler]

Hi guys,

I wanted to try jb-x86 on my old AMD Athlon XP but during boot it stucks with the error "Illegal Instruction". After some searching for a solution I read that since Honeycomb the CPU has to have SSE-2 at minimum but you could still recompile it with the " TARGET_CPU_SMP=false" option.
Is this possible at jb-x86, too? Can I run jb-x86 on an old Athlon XP?

Thanks!

Personally, I don't know, but I would seriously doubt that TARGET_CPU_SMP would fix the issue. SMP is support for more than a single CPU/core, you might want to look for options relating to SSE or SIMD (if they exist)

Hi Eric

1. The patch will disable the dalvik JIT and remove a lots of SSE2/3 instructions.

2. Change the busybox initrd and installer to older version.

3. recompile 

   # make -j8 iso_img TARGET_PRODUCT=android_x86 TARGET_CPU_SMP=false ARCH_X86_HAVE_SSE2=false ARCH_X86_HAVE_SSSE3=false  TARGET_KERNEL_CONFIG=/path_of_your_kernel_config_file/kernel_config.config

Hi Owen,
I'm confused, this patch disable dalvik JIT, ¿so the OS will use ART?
¿Where I put this patches? ¿In the kernel path?
And last one, ¿There is any possibility to put a new patch for 4.4.2 or rebuild a new ISO without SSE2/SSE3 requirement?
Best Regards

I came across https://sites.google.com/site/twisteroidambassador/android-x86/kitkat-non-sse3-build while surfing for a way to make the kitkat version work on my old Pentium4 which has only SSE2. Its works well in Virtualbox.
