| What: /sys/class/ata_... | ||
| Date: August 2008 | ||
| Contact: Gwendal Grignou<gwendal@google.com> | ||
| Description: | ||
|
|
||
| Provide a place in sysfs for storing the ATA topology of the system. This allows | ||
| retrieving various information about ATA objects. | ||
|
|
||
| Files under /sys/class/ata_port | ||
| ------------------------------- | ||
|
|
||
| For each port, a directory ataX is created where X is the ata_port_id of | ||
| the port. The device parent is the ata host device. | ||
|
|
||
| idle_irq (read) | ||
|
|
||
| Number of IRQ received by the port while idle [some ata HBA only]. | ||
|
|
||
| nr_pmp_links (read) | ||
|
|
||
| If a SATA Port Multiplier (PM) is connected, number of link behind it. | ||
|
|
||
| Files under /sys/class/ata_link | ||
| ------------------------------- | ||
|
|
||
| Behind each port, there is a ata_link. If there is a SATA PM in the | ||
| topology, 15 ata_link objects are created. | ||
|
|
||
| If a link is behind a port, the directory name is linkX, where X is | ||
| ata_port_id of the port. | ||
| If a link is behind a PM, its name is linkX.Y where X is ata_port_id | ||
| of the parent port and Y the PM port. | ||
|
|
||
| hw_sata_spd_limit | ||
|
|
||
| Maximum speed supported by the connected SATA device. | ||
|
|
||
| sata_spd_limit | ||
|
|
||
| Maximum speed imposed by libata. | ||
|
|
||
| sata_spd | ||
|
|
||
| Current speed of the link [1.5, 3Gps,...]. | ||
|
|
||
| Files under /sys/class/ata_device | ||
| --------------------------------- | ||
|
|
||
| Behind each link, up to two ata device are created. | ||
| The name of the directory is devX[.Y].Z where: | ||
| - X is ata_port_id of the port where the device is connected, | ||
| - Y the port of the PM if any, and | ||
| - Z the device id: for PATA, there is usually 2 devices [0,1], | ||
| only 1 for SATA. | ||
|
|
||
| class | ||
| Device class. Can be "ata" for disk, "atapi" for packet device, | ||
| "pmp" for PM, or "none" if no device was found behind the link. | ||
|
|
||
| dma_mode | ||
|
|
||
| Transfer modes supported by the device when in DMA mode. | ||
| Mostly used by PATA device. | ||
|
|
||
| pio_mode | ||
|
|
||
| Transfer modes supported by the device when in PIO mode. | ||
| Mostly used by PATA device. | ||
|
|
||
| xfer_mode | ||
|
|
||
| Current transfer mode. | ||
|
|
||
| id | ||
|
|
||
| Cached result of IDENTIFY command, as described in ATA8 7.16 and 7.17. | ||
| Only valid if the device is not a PM. | ||
|
|
||
| gscr | ||
|
|
||
| Cached result of the dump of PM GSCR register. | ||
| Valid registers are: | ||
| 0: SATA_PMP_GSCR_PROD_ID, | ||
| 1: SATA_PMP_GSCR_REV, | ||
| 2: SATA_PMP_GSCR_PORT_INFO, | ||
| 32: SATA_PMP_GSCR_ERROR, | ||
| 33: SATA_PMP_GSCR_ERROR_EN, | ||
| 64: SATA_PMP_GSCR_FEAT, | ||
| 96: SATA_PMP_GSCR_FEAT_EN, | ||
| 130: SATA_PMP_GSCR_SII_GPIO | ||
| Only valid if the device is a PM. | ||
|
|
||
| spdn_cnt | ||
|
|
||
| Number of time libata decided to lower the speed of link due to errors. | ||
|
|
||
| ering | ||
|
|
||
| Formatted output of the error ring of the device. |

| Date: August 2010 | ||
| Contact: Stefan Achatz <erazor_de@users.sourceforge.net> | ||
| Description: It is possible to switch the cpi setting of the mouse with the | ||
| press of a button. | ||
| When read, this file returns the raw number of the actual cpi | ||
| setting reported by the mouse. This number has to be further | ||
| processed to receive the real dpi value. | ||

| Description: When read, this file returns the raw integer version number of the | ||
| firmware reported by the mouse. Using the integer value eases | ||
| further usage in other programs. To receive the real version | ||
| number the decimal point has to be shifted 2 positions to the | ||

| Description: The mouse can store 5 profiles which can be switched by the | ||

| profile_settings holds informations like resolution, sensitivity | ||

| When written, this file lets one write the respective profile | ||
| settings back to the mouse. The data has to be 13 bytes long. | ||
| The mouse will reject invalid data. | ||
| Which profile to write is determined by the profile number | ||
