I added some debug code to the agp_generic_create_gatt_table() function. This is the debug output of it (function renamed to articias_create_gatt_table()): agpgart: [ARTICIAS] articias_fetch_size() agpgart: [ARTICIAS] * non masked temp = 0x1 agpgart: [ARTICIAS] * aperature size loop index #0 agpgart: [ARTICIAS] * values[0].size_value = 1 agpgart: [ARTICIAS] * masked temp = 0x1 agpgart: [ARTICIAS] * values[0].size = 4 agpgart: [ARTICIAS] * current_size->size = 4 agpgart: [ARTICIAS] * current_size->page_order = 1 agpgart: [ARTICIAS] * current_size->num_entries = 1024 agpgart: [ARTICIAS] * current_size->size_value = 1 agpgart: [ARTICIAS] articias_create_gatt_table() agpgart: [ARTICIAS] * table address = 0xdfad2000 agpgart: [ARTICIAS] * table end address = 0xdfad3fff agpgart: [ARTICIAS] * page = 0xc08f9a80 agpgart: [ARTICIAS] * gatt_table_real = 0xdfad2000 agpgart: [ARTICIAS] * agp_gatt_table = 0xdfad2000 agpgart: [ARTICIAS] * virt_to_gart(table) = 0x1fad2000 __ioremap(): phys addr 1fad2000 is RAM lr c000ec3c agpgart: [ARTICIAS] * gatt_table_real = 0x0 agpgart: unable to get memory for graphics translation table. agpgart: agp_backend_initialize() failed. agpgart-articias: probe of 0000:00:00.0 failed with error -12 As far as I can see, the physical address of the table is in the PCI memory range, right? Any ideas? Thanks! Regards, Gerhard -- Lust, ein paar Euro nebenbei zu verdienen? Ohne Kosten, ohne Risiko!
