277 | What: ACPI hotkey driver (CONFIG_ACPI_HOTKEY) | ||
278 | When: 2.6.21 | ||
279 | Why: hotkey.c was an attempt to consolidate multiple drivers that use | ||
280 | ACPI to implement hotkeys. However, hotkeys are not documented | ||
281 | in the ACPI specification, so the drivers used undocumented | ||
282 | vendor-specific hooks and turned out to be more different than | ||
283 | the same. | ||
284 | |||
285 | Further, the keys and the features supplied by each platform | ||
286 | are different, so there will always be a need for | ||
287 | platform-specific drivers. | ||
288 | |||
289 | So the new plan is to delete hotkey.c and instead, work on the | ||
290 | platform specific drivers to try to make them look the same | ||
291 | to the user when they supply the same features. | ||
292 | |||
293 | hotkey.c has always depended on CONFIG_EXPERIMENTAL | ||

299 | What: /sys/firmware/acpi/namespace | ||
300 | When: 2.6.21 | ||
301 | Why: The ACPI namespace is effectively the symbol list for | ||
302 | the BIOS. The device names are completely arbitrary | ||
303 | and have no place being exposed to user-space. | ||
304 | |||
305 | For those interested in the BIOS ACPI namespace, | ||
306 | the BIOS can be extracted and disassembled with acpidump | ||
307 | and iasl as documented in the pmtools package here: | ||

314 | What: /proc/acpi/button | ||
315 | When: August 2007 | ||
316 | Why: /proc/acpi/button has been replaced by events to the input layer | ||
317 | since 2.6.20. | ||
