* ACPI: ibm-acpi: cleanup fan_writeHenrique de Moraes Holschuh2006-12-07
| | | | | | | This patch cleans up fan_write so that it is much easier to read and extend. It separates the proc api handling from the operations themselves. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br>
* ACPI: ibm-acpi: break fan_read into separate functionsHenrique de Moraes Holschuh2006-12-07
| | | | | | | This patch breaks fan_read mechanics into a generic function to get fan status and speed, and leaves only the procfs interface code in fan_read. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br>
* ACPI: ibm-acpi: clean up fan_readHenrique de Moraes Holschuh2006-12-07
| | | | | | | | | | | | | | This patch cleans up fan_read so that it is much easier to read and extend. The patch fixes the userspace ABI to return "status: not supported" (like all other ibm-acpi functions) when neither fan status or fan control are possible. It also fixes the userspace ABI to return EIO if ACPI access to the EC fails, instead of returning "status: unreadable" or "speed: unreadable".

* ACPI: ibm-acpi: prepare to cleanup fan_read and fan_writeHenrique de Moraes Holschuh2006-12-07
| | | | | | | | This patch lays some groundwork for a fan_read and fan_write cleanup in the next patches. To do so, it provides a new fan_init initializer, and also some constants (through enums). Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br>
* ACPI: ibm-acpi: document thermal sensor locations for the A31Henrique de Moraes Holschuh2006-12-07
| | | | | | | The A31 has a very atypical layout, so I separated its thermal sensors location in a separate patch. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br>
* ACPI: ibm-acpi: Implement direct-ec-access thermal reading modes for up to ↵Henrique de Moraes Holschuh2006-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 16 sensors This patch extends ibm-acpi to support reading thermal sensors directly through ACPI EC register access. It uses a DMI match to detect ThinkPads with a new-style embedded controller, that are known to have forward- compatible register maps and use 0x00 to fill in non-used registers and export thermal sensors at EC offsets 0x78-7F and 0xC0-C7. Direct ACPI EC register access is implemented for 8-sensor and 16-sensor new-style ThinkPad controller firmwares as an experimental feature. The code does some limited sanity checks on the temperatures read through EC access, and will default to the old ACPI TMP0-7 mode if anything is amiss. Userspace ABI is not changed for 8 sensors, but /proc/acpi/ibm/thermal is extended for 16 sensors if the firmware supports 16 sensors. A documentation update is also provided. The information about the ThinkPad register map was determined by studying ibm-acpi "ecdump" output from various ThinkPad models, submitted by subscribers of the linux-thinkpad mailinglist. Futher information was gathered from the DSDT tables, as they describe the EC register map in recent ThinkPads. DSDT source shows that TMP0-7 access and direct register access are actually the same thing on these firmwares, but unfortunately IBM never did update their DSDT EC register map to export TMP8-TMP15 for the second range of sensors.

* ACPI: ibm-acpi: Use a enum to select the thermal sensor reading strategyHenrique de Moraes Holschuh2006-12-07
| | | | | | | | | This patch consolidades all decisions regarding the strategy to be used to read thinkpad thermal sensors into a single enum, and refactors the thermal sensor reading code to use a much more readable (and easier to extend) switch() construct, in a separate function.

* ACPI: ibm-acpi: do not use / in driver namesHenrique de Moraes Holschuh2006-12-07
| | | | | | | | ibm-acpi uses sub-device names like ibm/hotkey, which get in the way of a sysfs conversion. Fix it to use ibm_hotkey instead. Thanks to Zhang Rui for noticing this. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes crypto_alloc_base() return proper return value. - If kzalloc() failure happens within __crypto_alloc_tfm(), crypto_alloc_base() returns NULL. But crypto_alloc_base() is supposed to return error code as pointer.
