| | | | | | | | | | | | | | | | | | | | | | In the interest of making long-term branch maintenance incur as little technical debt on us as possible, we should not maintain any files on the branch we are not actually using. This has the added effect of making it extremely clear when merging CLs from the main branch when changes have the possibility to affect us. The follow-on CL adds a convenience script to actually pull updates from the main branch and generate a CL for the update.

* ec.tasklist: Consolidate duplicate commentsDaisuke Nojiri2019-04-081-11/+1
| | | | | | | | | | | | | | | | | | | | | | | It's simply a bad idea to describe a macro in multiple locations. It'll make it hard to change. It'll be difficult to keep all locations in sync. This patch replaces the comment duplicated in all ec.tasklist with a pointer to the CONFIG_TASK_LIST definition. The macro will be described in a single place (just like all/most other macros).

* Only includes necessary tasks for test binariesVic Yang2013-04-101-4/+6
| | | | | | | | | | | | | | | | | | | | This changes current TASK() syntax to TASK_BASE() and TASK_NORMAL(), where TASK_BASE is necessary for the EC to boot on a board and TASK_NORMAL represents the task that can be removed in a test binary. Tasks introduced by a test should be listed as TASK_TEST(). Note that this CL breaks current tests (many of them are broken anyway), which will be fixed in up coming CLs.

* Rename tasks to HOOKS and CHIPSETRandall Spangler2013-03-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Rename tasks TICK -> HOOKS The hooks task handles more than just the TICK hook now. X86POWER -> CHIPSET GAIAPOWER -> CHIPSET Kinda kludgy that the name of the task controls which chipset source gets included. Change this to a CONFIG_CHIPSET_{X86,GAIA} #define to make it easier to support future chipsets. Also, rename the task function to chipset_task() so ec.tasklist is chipset-agnostic. No code changes, just renaming constants and functions.

* Add tick taskRandall Spangler2012-10-301-0/+1
| | | | | | | | | | | | | | | | | | | Adds a new HOOK_TICK event which is called every 250ms (LM4) or 500ms (STM32). This will be used to consolidate a number of tasks which do small amounts of work infrequently, and previously needed their own task functions. This CL adds the tick task; subsequent CLs will consolidate watchdog and other tasks into tick hooks.

* Switch to variable-size stacksRandall Spangler2012-09-091-4/+5
| | | | | | | | | | | | | | | | | | | | Increase stack size slightly for vboot hash task since the vboot SHA256 function allocates ~300 bytes of stack data. Reduce stack size for watchdog, power LED, and a few other tasks with simple call trees where we can be sure an error path isn't going to blow past the reduced stack. This frees up ~1KB of RAM on STM32.
