This function can only modify a configuration requested via \fBcsx_RequestConfiguration\fR(9F). .SH STRUCTURE MEMBERS The structure members of \fBmodify_config_t\fR are: .sp .in +2 .nf uint32_t Socket; /* socket number */ uint32_t Attributes; /* attributes to modify */ uint32_t Vpp1; /* Vpp1 value */ uint32_t Vpp2; /* Vpp2 value */ .fi .in -2 .sp .LP The fields are defined as follows: .sp .ne 2 .na \fB\fBSocket\fR \fR .ad .RS 15n Not used in illumos, but for portability with other Card Services implementations, it should be set to the logical socket number. .RE .sp .ne 2 .na \fB\fBAttributes\fR \fR .ad .RS 15n This field is bit-mapped. The following bits are defined: .sp .ne 2 .na \fBCONF_ENABLE_IRQ_STEERING\fR .ad .RS 28n Enable IRQ steering. Set to connect the \fBPC \fRCard \fBIREQ \fRline to a previously selected system interrupt. .RE .sp .ne 2 .na \fBCONF_IRQ_CHANGE_VALID\fR .ad .RS 28n IRQ change valid. Set to request the \fBIRQ \fRsteering enable to be changed. .RE .sp .ne 2 .na \fBCONF_VPP1_CHANGE_VALID\fR .ad .RS 28n Vpp1 change valid. These bits are set to request a change to the corresponding voltage level for the \fBPC \fRCard. .RE .sp .ne 2 .na \fBCONF_VPP2_CHANGE_VALID\fR .ad .RS 28n Vpp2 change valid. These bits are set to request a change to the corresponding voltage level for the \fBPC \fRCard. .RE .sp .ne 2 .na \fBCONF_VSOVERRIDE\fR .ad .RS 28n Override VS pins. For Low Voltage keyed cards, must be set if a client desires to apply a voltage inappropriate for this card to any pin. After card insertion and prior to the first \fBcsx_RequestConfiguration\fR(9F) call for this client, the voltage levels applied to the card will be those specified by the Card Interface Specification. (See \fBWARNINGS\fR.) .RE .RE .sp .ne 2 .na \fB\fBVpp1\fR, \fBVpp2\fR\fR .ad .RS 15n Represent voltages expressed in tenths of a volt. Values from \fB0\fR to \fB25.5\fR volts may be set. To be valid, the exact voltage must be available from the system. To be compliant with the \fIPC Card 95 Standard, PCMCIA/JEIDA\fR, systems must always support \fB5.0\fR volts for both \fBVcc\fR and \fBVpp\fR. (See \fBWARNINGS\fR.) .RE .SH RETURN VALUES .ne 2 .na \fB\fBCS_SUCCESS\fR \fR .ad .RS 28n Successful operation. .RE .sp .ne 2 .na \fB\fBCS_BAD_HANDLE\fR \fR .ad .RS 28n Client handle is invalid or \fBcsx_RequestConfiguration\fR(9F) not done. .RE .sp .ne 2 .na \fB\fBCS_BAD_SOCKET\fR \fR .ad .RS 28n Error getting/setting socket hardware parameters. .RE .sp .ne 2 .na \fB\fBCS_BAD_VPP\fR \fR .ad .RS 28n Requested \fBVpp\fR is not available on socket. .RE .sp .ne 2 .na \fB\fBCS_NO_CARD\fR \fR .ad .RS 28n No \fBPC \fRCard in socket. .RE .sp .ne 2 .na \fB\fBCS_UNSUPPORTED_FUNCTION\fR \fR .ad .RS 28n No \fBPCMCIA \fRhardware installed. .RE .SH CONTEXT This function may be called from user or kernel context. .SH SEE ALSO .BR csx_RegisterClient (9F), .BR csx_ReleaseConfiguration (9F), .BR csx_ReleaseIO (9F), .BR csx_ReleaseIRQ (9F), .BR csx_RequestConfiguration (9F), .BR csx_RequestIO (9F), .BR csx_RequestIRQ (9F) .sp .LP \fIPC Card 95 Standard, PCMCIA/JEIDA\fR .SH WARNINGS .RS +4 .TP 1. \fBCONF_VSOVERRIDE\fR is provided for clients that have a need to override the information provided in the CIS. The client must exercise caution when setting this as it overrides any voltage level protection provided by Card Services. .RE .RS +4 .TP 2. Using \fBcsx_ModifyConfiguration()\fR to set \fBVpp\fR to \fB0\fR volts may result in the loss of a \fBPC \fRCard's state. Any client setting \fBVpp\fR to \fB0\fR volts is responsible for insuring that the \fBPC \fRCard's state is restored when power is re-applied to the card. .RE .SH NOTES Mapped \fBIO \fRaddresses can only be changed by first releasing the current configuration and \fBIO \fRresources with \fBcsx_ReleaseConfiguration\fR(9F) and \fBcsx_ReleaseIO\fR(9F), requesting new \fBIO \fRresources and a new configuration with \fBcsx_RequestIO\fR(9F), followed by \fBcsx_RequestConfiguration\fR(9F). .sp .LP \fBIRQ \fRpriority can only be changed by first releasing the current configuration and \fBIRQ \fRresources with \fBcsx_ReleaseConfiguration\fR(9F) and \fBcsx_ReleaseIRQ\fR(9F), requesting new \fBIRQ \fRresources and a new configuration with \fBcsx_RequestIRQ\fR(9F), followed by \fBcsx_RequestConfiguration\fR(9F). .sp .LP \fBVcc\fR can not be changed using \fBcsx_ModifyConfiguration()\fR. \fBVcc\fR may be changed by first invoking \fBcsx_ReleaseConfiguration\fR(9F), followed by \fBcsx_RequestConfiguration\fR(9F) with a new \fBVcc\fR value.
