All; As the below shows, the ramdisk problem has been circumvented by use of the cmdline option ramdisk_size=4660000.
Still experience terribly slow uart. Can anyone quickly point me to the appropriate interrupt components for the uartlite et al? Some other questions: 1. Are interrupts obtained via the platform_get_resource() call? 2. Are allocated interrupts issued starting at 0? 3. Is there a correlation between the xparameters_ml403.h entries below and the interrupt issued in 1, above? #define XPAR_PLB_TEMAC_0_IP2INTC_IRPT_MASK 0X000001 #define XPAR_OPB_INTC_0_PLB_TEMAC_0_IP2INTC_IRPT_INTR 0 #define XPAR_XUL_UART_INTERRUPT_MASK 0X000002 #define XPAR_OPB_INTC_0_XUL_UART_INTERRUPT_INTR 1 #define XPAR_INTC_0_TEMAC_0_VEC_ID XPAR_OPB_INTC_0_PLB_TEMAC_0_IP2INTC_IRPT_INTR #define XPAR_INTC_0_UARTLITE_0_VEC_ID XPAR_OPB_INTC_0_XUL_UART_INTERRUPT_INTR Thanks in advance for anyones help. -cy ================ [ 0.000000] Linux version 2.6.17.1 ([EMAIL PROTECTED]) (gcc version 3.4.2) #4 Mon Oct 23 19:47:51 UTC 2006 [ 0.000000] Xilinx ML403 Reference System (Virtex-4 FX) [ 0.000000] Built 1 zonelists [ 0.000000] Kernel command line: console=ttyUL0 single ip=off ramdisk_size=4660000 root=/dev/ram rw [ 0.000000] Xilinx INTC #0 at 0xD1000FC0 mapped to 0xFDFFFFC0 [ 0.000000] PID hash table entries: 512 (order: 9, 2048 bytes) [ 0.000151] Console: colour dummy device 80x25 [ 0.000560] Dentry cache hash table entries: 8192 (order: 3, 32768 bytes) [ 0.001270] Inode-cache hash table entries: 4096 (order: 2, 16384 bytes) [ 0.013923] Memory: 58572k available (1348k kernel code, 344k data, 80k init, 0k highmem) [ 0.200437] Mount-cache hash table entries: 512 [ 0.203119] checking if image is initramfs...it isn't (no cpio magic); looks like an initrd [ 2.505388] Freeing initrd memory: 4549k freed [ 2.509461] NET: Registered protocol family 16 [ 2.518975] NET: Registered protocol family 2 [ 2.583987] IP route cache hash table entries: 512 (order: -1, 2048 bytes) [ 2.584462] TCP established hash table entries: 2048 (order: 3, 32768 bytes) [ 2.584931] TCP bind hash table entries: 1024 (order: 2, 20480 bytes) [ 2.585217] TCP: Hash tables configured (established 2048 bind 1024) [ 2.585251] TCP reno registered [ 2.591638] io scheduler noop registered [ 2.591747] io scheduler anticipatory registered (default) [ 2.591902] io scheduler deadline registered [ 2.592039] io scheduler cfq registered [ 2.637280] serial irq #1 obtained from platform [ 2.637397] uartlite.0: ttyUL0 at MMIO 0xa0000000 (irq = 1) is a uartlite [ 42.667249] RAMDISK driver initialized: 16 RAM disks of 4660000K size 1024 blocksize [ 44.738763] eth%d: XTemac using sgDMA mode.
