257 | What: ACPI hotkey driver (CONFIG_ACPI_HOTKEY) | ||
258 | When: 2.6.21 | ||
259 | Why: hotkey.c was an attempt to consolidate multiple drivers that use | ||
260 | ACPI to implement hotkeys. However, hotkeys are not documented | ||
261 | in the ACPI specification, so the drivers used undocumented | ||
262 | vendor-specific hooks and turned out to be more different than | ||
263 | the same. | ||
264 | |||
265 | Further, the keys and the features supplied by each platform | ||
266 | are different, so there will always be a need for | ||
267 | platform-specific drivers. | ||
268 | |||
269 | So the new plan is to delete hotkey.c and instead, work on the | ||
270 | platform specific drivers to try to make them look the same | ||
271 | to the user when they supply the same features. | ||
272 | |||
273 | hotkey.c has always depended on CONFIG_EXPERIMENTAL | ||
