- request or release window resources
#include <sys/pccard.h> int32_t csx_RequestWindow(client_handle_t ch, window_handle_t *wh, win_req_t *wr);
int32_t csx_ReleaseWindow(window_handle_t wh);
Solaris DDI Specific (Solaris DDI)
Client handle returned from csx_RegisterClient(9F).
Pointer to a window_handle_t structure.
Pointer to a win_req_t structure.
The function csx_RequestWindow() requests a block of system address space be assigned to a PC Card in a socket.
The function csx_ReleaseWindow() releases window resources which were obtained by a call to csx_RequestWindow(). No adapter or socket hardware is modified by this function.
The csx_MapMemPage(9F) and csx_ModifyWindow(9F) functions use the window handle returned by csx_RequestWindow(). This window handle must be freed by calling csx_ReleaseWindow() when the client is done using this window.
The PC Card Attribute or Common Memory offset for this window is set by csx_MapMemPage(9F).
The structure members of win_req_t are:
uint32_t Socket; /* socket number */ uint32_t Attributes; /* window flags */ uint32_t Base.base; /* requested window */ /* base address */ acc_handle_t Base.handle; /* returned handle for /* base of window */ uint32_t Size; /* window size requested */ /* or granted */ uint32_t win_params.AccessSpeed; /* window access speed */ uint32_t win_params.IOAddrLines; /* IO address lines decoded */ uint32_t ReqOffset; /* required window offest */
The fields are defined as follows:
Not used in Solaris, but for portability with other Card Services implementations, it should be set to the logical socket number.
This field is bit-mapped. It is defined as follows:
WIN_MEMORY_TYPE_IO Window points to I/O space WIN_MEMORY_TYPE_CM Window points to Common Memory space WIN_MEMORY_TYPE_AM Window points to Attribute Memory space WIN_ENABLE Enable window WIN_DATA_WIDTH_8 Set window to 8-bit data path WIN_DATA_WIDTH_16 Set window to 16-bit data path WIN_ACC_NEVER_SWAP Host endian byte ordering WIN_ACC_BIG_ENDIAN Big endian byte ordering WIN_ACC_LITTLE_ENDIAN Little endian byte ordering WIN_ACC_STRICT_ORDER Program ordering references WIN_ACC_UNORDERED_OK May re-order references WIN_ACC_MERGING_OK Merge stores to consecutive locations WIN_ACC_LOADCACHING_OK May cache load operations WIN_ACC_STORECACHING_OK May cache store operations
Points to I/O space.
Points to common memory space.
These bits select which type of window is being requested. One of these bits must be set.
The client must set this bit to enable the window.
Describes device as big-endian.
These bits describe the endian characteristics of the device as big endian or little endian, respectively. Even though most of the devices will have the same endian characteristics as their busses, there are examples of devices with an I/O processor that has opposite endian characteristics of the busses. When either of these bits are set, byte swapping will automatically be performed by the system if the host machine and the device data formats have opposite endian characteristics. The implementation may take advantage of hardware platform byte swapping capabilities.
When this is specified, byte swapping will not be invoked in the data access functions.
The ability to specify the order in which the CPU will reference data is provided by the following Attributes bits, only one of which may be specified:
The data references must be issued by a CPU in program order. Strict ordering is the default behavior.
The CPU may re-order the data references. This includes all kinds of re-ordering (that is, a load followed by a store may be replaced by a store followed by a load).
The CPU may merge individual stores to consecutive locations. For example, the CPU may turn two consecutive byte stores into one halfword store. It may also batch individual loads. For example, the CPU may turn two consecutive byte loads into one halfword load. This bit also implies re-ordering.
The CPU may cache the data it fetches and reuse it until another store occurs. The default behavior is to fetch new data on every load. This bit also implies merging and re-ordering.
The CPU may keep the data in the cache and push it to the device (perhaps with other data) at a later time. The default behavior is to push the data right away. This bit also implies load caching, merging, and re-ordering.
These values are advisory, not mandatory. For example, data can be ordered without being merged or cached, even though a driver requests unordered, merged and cached together.
All other bits in the Attributes field must be set to 0.
On successful return from csx_RequestWindow(), WIN_OFFSET_SIZE is set in the Attributes field when the client must specify card offsets to csx_MapMemPage(9F) that are a multiple of the window size.
This field must be set to 0 on calling csx_RequestWindow().
On successful return from csx_RequestWindow(), the Base.handle field contains an access handle corresponding to the first byte of the allocated memory window which the client must use when accessing the PC Card's memory space via the common access functions. A client must not make any assumptions as to the format of the returned Base.handle field value.
On calling csx_RequestWindow(), the Size field is the size in bytes of the memory window requested. Size may be zero to indicate that Card Services should provide the smallest sized window available. On successful return from csx_RequestWindow(), the Size field contains the actual size of the window allocated.
This field specifies the access speed of the window if the client is requesting a memory window. The AccessSpeed field bit definitions use the format of the extended speed byte of the Device ID tuple. If the mantissa is 0 (noted as reserved in the PC Card 95 Standard), the lower bits are a binary code representing a speed from the following table:
|
To request a window that supports the WAIT signal, OR-in the WIN_USE_WAIT bit to the AccessSpeed value before calling this function.
It is recommended that clients use the csx_ConvertSpeed(9F) function to generate the appropriate AccessSpeed values rather than manually perturbing the AccessSpeed field.
If the client is requesting an I/O window, the IOAddrLines field is the number of I/O address lines decoded by the PC Card in the specified socket. Access to the I/O window is not enabled until csx_RequestConfiguration(9F) has been invoked successfully.
This field is a Solaris-specific extension that can be used by clients to generate optimum window offsets passed to csx_MapMemPage(9F).
