| 1930 | * knowledge on the IBM and Lenovo ThinkPad firmware for |
| 1931 | * the various ThinkPad models. The driver behaves |
| 1932 | * differently for KEY_RESERVED: such keys have their |
| 1933 | * hot key mask *unset* in mask_recommended, and also |
| 1934 | * in the initial hot key mask programmed into the |
| 1935 | * firmware at driver load time, which means the firm- |
| 1936 | * ware may react very differently if you change them to |
| 1937 | * something else; |
| 1938 | * |
| 1939 | * 2. You must be subscribed to the linux-thinkpad and |
| 1940 | * ibm-acpi-devel mailing lists, and you should read the |
| 1941 | * list archives since 2007 if you want to change the |
| 1942 | * keymaps. This requirement exists so that you will |
| 1943 | * know the past history of problems with the thinkpad- |
| 1944 | * acpi driver keymaps, and also that you will be |
| 1945 | * listening to any bug reports; |
| 1946 | * |
| 1947 | * 3. Do not send thinkpad-acpi specific patches directly to |
| 1948 | * for merging, *ever*. Send them to the linux-acpi |
| 1949 | * mailinglist for comments. Merging is to be done only |
| 1950 | * through acpi-test and the ACPI maintainer. |
| 1951 | * |
| 1952 | * If the above is too much to ask, don't change the keymap. |
| 1953 | * Ask the thinkpad-acpi maintainer to do it, instead. |

| 5027 | * ThinkPad EC register 0x84 (LSB), 0x85 (MSB): |
| 5028 | * Main fan tachometer reading (in RPM) |
| 5029 | * |
| 5030 | * This register is present on all ThinkPads with a new-style EC, and |
| 5031 | * it is known not to be present on the A21m/e, and T22, as there is |
| 5032 | * something else in offset 0x84 according to the ACPI DSDT. Other |
| 5033 | * ThinkPads from this same time period (and earlier) probably lack the |
| 5034 | * tachometer as well. |
| 5035 | * |
| 5036 | * Unfortunately a lot of ThinkPads with new-style ECs but whose firwmare |
| 5037 | * was never fixed by IBM to report the EC firmware version string |
| 5038 | * probably support the tachometer (like the early X models), so |
| 5039 | * detecting it is quite hard. We need more data to know for sure. |
| 5040 | * |
| 5041 | * FIRMWARE BUG: always read 0x84 first, otherwise incorrect readings |
| 5042 | * might result. |
