 ==== Summary ==== ==== Summary ====
  
-==== Outline ====+Allow gPXE to run as a usermode application under Linux on both i386 and x86_64. Hence opening new debugging possibilities and shortening the development cycle considerably.

-==== Milestones and Timeline ​====+==== Tasks ====
  
 +=== Already done ===
 +  * Add a ''​linux''​ ''​PLATFORM''​
 +    * Link against hacked ''​stdlib''​
 +    * Add linker scripts for ''​i386''​ and ''​x86_64''​ with tables support
 +  * Add the necessary subsystems for a tap network driver
 +      * ''​CONSOLE_LINUX''​
 +      * ''​TIMER_LINUX''​
 +      * ''​UACCESS_LINUX''​
 +      * ''​UMALLOC_LINUX''​
 +      * ''​NAP_LINUX''​
 +      * ''​SMBIOS_LINUX''​ (empty)
 +  * Add a tap network driver
 +  * Add command-line arguments allowing configuration of the tap driver
 +  * Drop the stdlib dep
 +    * Implement ''​syscall()''​ and ''​linux_*''​ on top of it where possible
 +    * Implement ''​linux_realloc''​
 +    * Implement ''​_start''​
 +    * Make it not too hard to switch to linking to stdlib for debugging purposes
 +=== Current ===
 +  * Making gPXE valgrindable
 +=== Planned for near future ===
 +  * Research how to map gPXE's driver API to hardware via kernel
