[ale] Use cloud guest to compile kernel

[Raj Wurttemberg]

Why not just cross-compile (-march=i586)  on your local system and then upload the finished product? Make sure to use the “-j” switch also to keep all of the CPUs busy.

Is this a bad idea?

 

I need to compile a 4.7.2 kernel for i586.  The kernel config is copied from debian jessie with CONFIG_M586TSC=y.

 

I don't have 2 days to wait.  

 

1.  Spin up a CentOS 6.X 32 bit guest at Digital Ocean with 8 cores and 16GB of ram.  This is $0.25/ht

2. Transfer linux-4.7.2.tar.xz and the config to it.

3.  Unpack, copy the config to .config, make, create package, and transfer back to the i586 hardware.

4.  Delete the guest. I only pay for the usage.

 

I'm doing this on a Digital Ocean guest of lowest power.  Only 0.007/hr.  It is still taking a long time. 

I need to build the same kernel, but for i586, i686, and x86_64.  I have the configs ready to go.  I'm also perfecting my packaging too so I may have to build a few times.

 

I making assumptions based on my assumption that I can use 8 cores at 100% each for a couple hours.  With Azure I can pay for a quarter core for testing under Winders.
