videoprt.nostrip.sys
by Ge van Geldorp 27 Jan '05

27 Jan '05

It seems videoprt.nostrip.sys is somewhat messed up. I've attached the output of "objdump -p videoprt.nostrip.sys". Data Directory Entry 1 says there's an import directory at 0x0000b000. Then down under "PE File Base Relocations (interpreted .reloc section contents)" we find: Virtual Address: 0000b000 Chunk size 12 (0xc) Number of fixups 2 reloc 0 offset 14 [b014] HIGHLOW reloc 1 offset 20 [b020] HIGHLOW When the module is loaded, the relocations are applied. This messes up the import table, with the result that the module fails to load (copy videoprt.nostrip.sys to \reactos\system32\drivers\videoprt.sys and boot ReactOS). The 2 relocations given above are not present in the "normal" videoprt.sys module. I'm inclined to blame gcc (I'm using 3.4.1) or more likely binutils (2.15.90 20040222) for this, but before I make Filip unhappy, does anyone know if we're doing something wrong during the build process?

We've got the plan set-up in our minds and it should be committed in less then a week, unless unexpected things happen. Speaking of which, is anyone against not making ACPI a compile-time instruction? It just makes debugging harder, one more thing to worry about, and I don't see the point either...I think it makes much more sense to have some kind of ACPISupported global variable that we either set at boot-up with proper table queries, and/or that the user can specify with an /ACPI command-line flag. Best regards, Alex Ionescu

new binutils snapshot

http://sourceforge.net/project/showfiles.php?group_id=2435 Does this make those issues (dlltool I think) with using the previous snapshot go away?

Slab cache
by Hartmut Birr 25 Jan '05

25 Jan '05

Hi, do we need the slab cache in ntoskrnl\mm\slab.c? I've replaced the kmap functions (ntoskrnl\mm\kmap.c) by a process local mapping (hyperspace). The slab cache needs the mapping for a longer time and cannot use the hyperspace mapping. I would remove the slab cache, because it is not used by any of the kernel functions. - Hartmut

user mode exceptions
by Hartmut Birr 25 Jan '05

25 Jan '05

Hi, on a user mode exception, I get hundreds of lines like this: (i386/exception.c:96) RtlpDispatchException() Dumping exception registrations: (0x0065FFE0) HANDLER (0x7C82CEAF) (0x7FFDF000) HANDLER (0x00000000) (i386/exception.c:96) RtlpDispatchException() Dumping exception registrations: (0x0065FFE0) HANDLER (0x7C82CEAF) (0x7FFDF000) HANDLER (0x00000000) (i386/exception.c:96) RtlpDispatchException() Dumping exception registrations: It needs a very large time, if ros does response again. It occurs on real hardware. Debugprints are going over a serial line. - Hartmut

But we use them on each directory except the root. The index from fcb is also used to update the entry of a file in its parent directory. For looking for a directory, '.' has index 0, '..' has index 1 and 'foo' has index 2 and so on. The real index of 'foo' is 0. We must make a difference between the real and the search index. I've modified some parts of freeldr and usetup. I can create and install ros on a fatx partition on a normal pc. I've also load vfatfs on W2K. At the beginning, the wrong index has scrambled the fatx partition. - Hartmut
