LDSO Question

[Sam Kerr]

I enabled debugging output for LDSO. The relevant output for my scenario is:

	thread 'ldso' has id 0x01020002 (task = 0x2, thread = 0x8)
	thread 'ldso' has id 0x04804002 (task = 0x9, thread = 0x1)
	[init -> ldso] Starting ldso ...
	[init -> ldso] /libexec/ld-elf.so.1 is initialized, base address = 30000
	[init -> ldso] RTLD dynamic = 57974
	[init -> ldso] RTLD pltgot  = 0
	[init -> ldso] loading main program
	[init -> ldso] void* mmap(void*, size_t, int, int, int, off_t): addr: 30000 length: 3c000 flags: 20002
	[init -> ldso] void* mmap(void*, size_t, int, int, int, off_t): fd: 0, prot: 5 offs: 1000
	[init -> ldso] realloc - not yet implemented
	04804002 pf @ fffffffc, ip=000432ad
	--- "KD# user touches kernel area" ---
	--------------------------------- (eip=f010c342, esp=f01163c7) ---
	> go
	no RM attachment (READ pf_addr=fffffffc pf_ip=432ad from 1201 (raw 04804002))
	invalid signal-context capability
 
I wasn't really sure what to do as far as config files went. I found the following through  a google search:

    <config>
        <parent-provides>
            <service name="ROM"/>
            <service name="RAM"/>
            <service name="IRQ"/>
            <service name="IO_MEM"/>
            <service name="IO_PORT"/>
            <service name="CAP"/>
            <service name="PD"/>
            <service name="RM"/>
            <service name="CPU"/>
            <service name="LOG"/>
        </parent-provides>
    
        <default-route>
            <any-service> <parent/> <any-child/> </any-service>
        </default-route>
        <start name="ps2_drv">
            <resource name="RAM" quantum="1M"/>
            <provides><service name="Input"/></provides>
        </start>
        <start name="pci_drv">
                <resource name="RAM" quantum="1M"/>
                <provides><service name="PCI"/></provides>
        </start>
        <start name="timer">
            <resource name="RAM" quantum="1M"/>
            <provides><service name="Timer"/></provides>
        </start>
        <start name="nitpicker">

            <provides><service name="Nitpicker"/></provides>
        </start>
        <start name="vesa_drv">

            <provides><service name="Framebuffer"/></provides>
        </start>
        <start name="launchpad">
            <resource name="RAM" quantum="32M"/>
        </start>
        <start name="ldso">
            <resource name="RAM" quantum="32M"/>
        </start>
        <start name="sharedlib">
            <resource name="RAM" quantum="10M"/>
        </start>
        <memsection name="ldso" file="ldso" direct="true" />
    </config>

Thanks for any help!
