In typical fashion, getting documentation about this * controller is about as easy as squeezing blood from a stone. Here * is more or less what I know: * * - The Hermes controller is firmware driven, and the host interacts * with the Hermes via a firmware interface, which can change. * * - The Hermes is described in a document called: "Hermes Firmware * WaveLAN/IEEE Station Functions," document #010245, which of course * Lucent will not release without an NDA. * * - Lucent has created a library called HCF (Hardware Control Functions) * though which it wants developers to interact with the card. The HCF * is needlessly complex, ill conceived and badly documented. Actually, * the comments in the HCP code itself aren't bad, but the publically * available manual that comes with it is awful, probably due largely to * the fact that it has been emasculated in order to hide information * that Lucent wants to keep proprietary. The purpose of the HCF seems * to be to insulate the driver programmer from the Hermes itself so that * Lucent has an excuse not to release programming in for it. * * - Lucent only makes available documentation and code for 'HCF Light' * which is a stripped down version of HCF with certain features not * implemented, most notably support for 802.11 frames. * * - The HCF code which I have seen blows goats. Whoever decided to * use a 132 column format should be shot. * * Rather than actually use the Lucent HCF library, I have stripped all * the useful information from it and used it to create a driver in the * usual BSD form. Note: I don't want to hear anybody whining about the * fact that the Lucent code is GPLed and mine isn't. I did not actually * put any of Lucent's code in this driver: I only used it as a reference * to obtain information about the underlying hardware. The Hermes * programming interface is not GPLed, so bite me. */ /* * Size of Hermes & Prism2 I/O space. */ #define WI_IOSIZE 0x40 /* * Hermes & Prism2 register definitions */ /* Hermes command/status registers. */ #define WI_COMMAND 0x00 #define WI_PARAM0 0x02 #define WI_PARAM1 0x04 #define WI_PARAM2 0x06 #define WI_STATUS 0x08 #define WI_RESP0 0x0A #define WI_RESP1 0x0C #define WI_RESP2 0x0E /* Command register values. */ #define WI_CMD_BUSY 0x8000 /* busy bit */ #define WI_CMD_INI 0x0000 /* initialize */ #define WI_CMD_ENABLE 0x0001 /* enable */ #define WI_CMD_DISABLE 0x0002 /* disable */ #define WI_CMD_DIAG 0x0003 #define WI_CMD_ALLOC_MEM 0x000A /* allocate NIC memory */ #define WI_CMD_TX 0x000B /* transmit */ #define WI_CMD_NOTIFY 0x0010 #define WI_CMD_INQUIRE 0x0011 #define WI_CMD_ACCESS 0x0021 #define WI_CMD_PROGRAM 0x0022 #define WI_CMD_READEE 0x0030 #define WI_CMD_TEST 0x0038 /* PRISM2 test mode */ #define WI_CMD_CODE_MASK 0x003F /* * Reclaim qualifier bit, applicable to the * TX and INQUIRE commands. */ #define WI_RECLAIM 0x0100 /* reclaim NIC memory */ /* * ACCESS command qualifier bits. */ #define WI_ACCESS_READ 0x0000 #define WI_ACCESS_WRITE 0x0100 /* * PROGRAM command qualifier bits. */ #define WI_PROGRAM_DISABLE 0x0000 #define WI_PROGRAM_ENABLE_RAM 0x0100 #define WI_PROGRAM_ENABLE_NVRAM 0x0200 #define WI_PROGRAM_NVRAM 0x0300 /* * DEBUG mode options. */ #define WI_TEST_MONITOR 0x0B /* monitor mode for testing */ /* Status register values */ #define WI_STAT_CMD_CODE 0x003F #define WI_STAT_DIAG_ERR 0x0100 #define WI_STAT_INQ_ERR 0x0500 #define WI_STAT_CMD_RESULT 0x7F00 /* memory handle management registers */ #define WI_INFO_FID 0x10 #define WI_RX_FID 0x20 #define WI_ALLOC_FID 0x22 #define WI_TX_CMP_FID 0x24 /* * Buffer Access Path (BAP) registers. * These are I/O channels.
