By giving an HCMD_INI first, this problem is worked around. + *2b: Experimentally it is determined over a wide range of F/W versions that waiting for the for Cmd bit in + * Ev register gives a workable strategy. The available documentation does not give much clues. + *4: clear and initialize the IFB + * The HCF house keeping info is designed such that zero is the appropriate initial value for as much as + * feasible IFB-items. + * The readable fields mentioned in the description section and some HCF specific fields are given their + * actual value. + * IFB_TickIni is initialized at best guess before calibration + * Hcf_connect defaults to "no interrupt generation" (implicitly achieved by the zero-filling). + *6: Register compile-time linked MSF Routine and set default filter level + * cast needed to get around the "near" problem in DOS COM model + * er C2446: no conversion from void (__near __cdecl *)(unsigned char __far *,unsigned int,unsigned short,int) + * to void (__far __cdecl *)(unsigned char __far *,unsigned int,unsigned short,int) + *8: If a command is apparently still active (as indicated by the Busy bit in Cmd register) this may indicate a + * blocked cmd pipe line. To unblock the following actions are done: + * - Ack everything + * - Wait for Busy bit drop in Cmd register + * - Wait for Cmd bit raise in Ev register + * The two waits are combined in a single HCF_WAIT_WHILE to optimize memory size. If either of these waits + * fail (prot_cnt becomes 0), then something is serious wrong. Rather than PANICK, the assumption is that the + * next cmd_exe will fail, causing the HCF to go into DEFUNCT mode + *10: Ack everything to unblock a (possibly blocked) cmd pipe line + * Note 1: it is very likely that an Alloc event is pending and very well possible that a (Send) Cmd event is + * pending on non-initial calls + * Note 2: it is assumed that this strategy takes away the need to ack every conceivable event after an + * Hermes Initialize + *12: Only H-II NEEDS the Hermes Initialize command. Due to the different semantics for H-I and H-II + * Initialize command, init() does not (and can not, since it is called e.g. after a download) execute the + * Hermes Initialize command. Executing the Hermes Initialize command for H-I would not harm but not do + * anything useful either, so it is skipped. + * The return status of cmd_exe is ignored. It is assumed that if cmd_exe fails, init fails too + *14: use io_base as a flag to merge hcf_connect and hcf_disconnect into 1 routine + * the call to init and its subsequent call of cmd_exe will return HCF_ERR_NO_NIC if appropriate. This status + * is (badly) needed by some legacy combination of NT4 and card services which do not yield an I/O address in + * time. + * + *.NOTICE + * On platforms where the NULL-pointer is not a bit-pattern of all zeros, the zero-filling of the IFB results + * in an incorrect initialization of pointers. + * The implementation of the MailBox manipulation in put_mb_info protects against the absence of a MailBox + * based on IFB_MBSize, IFB_MBWp and ifbp->IFB_MBRp. This has ramifications on the initialization of the + * MailBox via hcf_put_info with the CFG_REG_MB type, but it prevents dependency on the "NULL-"ness of + * IFB_MBp. + * + *.NOTICE + * There are a number of problems when asserting and logging hcf_connect, e.g. + * - Asserting on re-entrancy of hcf_connect by means of + * "HCFASSERT( (ifbp->IFB_AssertTrace & HCF_ASSERT_CONNECT) == 0, 0 )" is not useful because IFB contents + * are undefined + * - Asserting before the IFB is cleared will cause mdd_assert() to interpret the garbage in IFB_AssertRtn + * as a routine address + * Therefore HCFTRACE nor HCFLOGENTRY is called by hcf_connect. + *.ENDDOC END DOCUMENTATION + * + ************************************************************************************************************/ int hcf_connect( IFBP ifbp, hcf_io io_base ) { -int rc = HCF_SUCCESS; -hcf_io io_addr; -hcf_32 prot_cnt; -hcf_8 *q; -LTV_STRCT x; + int rc = HCF_SUCCESS; + hcf_io io_addr; + hcf_32 prot_cnt; + hcf_8 *q; + LTV_STRCT x; #if HCF_ASSERT hcf_16 xa = ifbp->IFB_FWIdentity.typ; /* is assumed to cause an assert later on if hcf_connect is called without intervening hcf_disconnect. @@ -1163,51 +1129,51 @@ LTV_STRCT x; */ #endif // HCF_ASSERT - if ( io_base == HCF_DISCONNECT ) { //disconnect + if ( io_base == HCF_DISCONNECT ) { //disconnect io_addr = ifbp->IFB_IOBase; - OPW( HREG_INT_EN, 0 ); //;?workaround against dying F/W on subsequent hcf_connect calls - } else { //connect /* 0 */ + OPW( HREG_INT_EN, 0 ); //;?workaround against dying F/W on subsequent hcf_connect calls + } else { //connect /* 0 */ io_addr = io_base; } #if 0 //;? if a subsequent hcf_connect is preceded by an hcf_disconnect the wakeup is not needed !! #if HCF_SLEEP - OUT_PORT_WORD( .....+HREG_IO, HREG_IO_WAKEUP_ASYNC ); //OPW not yet useable - MSF_WAIT(800); // MSF-defined function to wait n microseconds. + OUT_PORT_WORD( .....+HREG_IO, HREG_IO_WAKEUP_ASYNC ); //OPW not yet useable + MSF_WAIT(800); // MSF-defined function to wait n microseconds. note that MSF_WAIT uses not yet defined!!!!
