I don't understand why this error occurs since the types all seem to
match.
Relevant lines from src/sys/dev/advansys/adv_pci.c:
/* Allocate a dmatag for our transfer DMA maps */
/* XXX Should be a child of the PCI bus dma tag */
error = bus_dma_tag_create(/*parent*/NULL, /*alignment*/1,
/*boundary*/0,
/*lowaddr*/ADV_PCI_MAX_DMA_ADDR,
/*highaddr*/BUS_SPACE_MAXADDR,
/*filter*/NULL, /*filterarg*/NULL,
/*maxsize*/BUS_SPACE_MAXSIZE_32BIT,
/*nsegments*/BUS_SPACE_UNRESTRICTED,
/*maxsegsz*/ADV_PCI_MAX_DMA_COUNT,
/*flags*/0,
197 -----> &adv->parent_dmat);
Yet in src/sys/alpha/include/bus.h:
typedef struct bus_dma_tag *bus_dma_tag_t;
...
int bus_dma_tag_create(bus_dma_tag_t parent, bus_size_t alignemnt,
bus_size_t boundary, bus_addr_t lowaddr,
bus_addr_t highaddr, bus_dma_filter_t *filtfunc,
void *filtfuncarg, bus_size_t maxsize, int
nsegments,
bus_size_t maxsegsz, int flags, bus_dma_tag_t
*dmat);
And advlib.h:
struct adv_softc {
...
bus_dma_tag_t parent_dmat;
}
Everything seems to line up, why the warning?
