Marc later I identified it and confirmed that ther was no issue with write of 0x7c. In the meantime I was going through the PCI code of XFree86 file "sparcPci.c" in function sparcPciInit (). I came across the following expression for mapping the PCI aperture memory. There seems to be some type mismatch for the fourth parameter.
domain.pci = (char *)sparcMapAperture(-1, VIDMEM_MMIO,
pci_addr + PCI_MAKE_TAG(domain.bus_min, 0, 0),
PCI_MAKE_TAG(domain.bus_max - domain.bus_min + 1, 0, 0)) -
PCI_MAKE_TAG(domain.bus_min, 0, 0);
ie there seems to be one extra bracket closed before the "-". Is this the way the final expreessions needs to be. I am not sure. Can you look into it. PCI_MAKE_TAG(domain.bus_max - domain.bus_min + 1, 0, 0)) -^
That not-so-extra parenthesis ends the arguments to be passed to sparcMapAperture().
Another Issue that I came across was that printing using xf86MsgVerb behaves abnormally. I am having this issue whne I have more than one prameter for xf86MsgVerb. Trying to do folloiwng has issue.
data1 = 0x0;
data2 = 0x2000000;
xf86MsgVerb ("Value data1 = 0x%x data2 = 0x%x \n", data1, data2)Look at the prototype for that function in common/xf86.h.
