==== TCP cleanup ==== === Cleanup TCP close actions === * Reduce duplicate code by separating tcp_terminate() from tcp_close(). * Use tcp_terminate to immediately free all tcp resources. * Use tcp_close() to bing TCP connection to closing state. * Make tcp_close() function simpler, not doing different job in different state. ==== Trace gPXE boot initialize steps about memory environment setup ==== * After recent Michael Brown's [prefix] patch-set: * [prefix] Add A20-enabling code in libflat * [prefix] Move flatten_real_mode to libflat.S * [prefix] Move flatten_real_mode to .text16.early * [prefix] Add .text16.early section * [prefix] Use flat real mode for access to high memory * [prefix] Use flat real mode instead of real mode * gPXE now works fully on [[http://en.wikipedia.org/wiki/Unreal_mode|Flat real mode]]. * Here is another [[http://www.df.lth.se/~john_e/gems/gem0022.html|nice document]] explains it. * Which solved the problem that big image relocate failure. * We can now safely modify the heap_size as we want. :)
