List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hello, I have been investigating the prep breakage of the sym53c8xx driver on my powerstack II in recent kernels, and traced it to the residual data patch, or more exactly to the whole prep_pci.c/prep_setup.c patches that where introduced between 2.6.9-rc1 and 2.6.9-rc1-bk1. I didn't have time to find more details as the patch is not so small, and seems to do many things, and linux.bkbits.net seems done right now. Mmm, after a bit more of investigation, the changeset breaking it is : # This is a BitKeeper generated diff -Nru style patch. # # ChangeSet # 2004/08/16 10:35:18-07:00 trini@kernel.crashing.org # ppc32: On PReP, use residual data for PCI dev -> IRQ, and use it. # # Signed-off-by: Leigh Brown # Signed-off-by: Tom Rini # # include/asm-ppc/residual.h # 2004/08/16 10:35:09-07:00 trini@kernel.crashing.org +7 -0 # This adds a function to use the residual data to determine the IRQ # for a given PCI device, and changes prep_pcibios_fixup() to use it. # # arch/ppc/platforms/residual.c # 2004/08/16 10:35:09-07:00 trini@kernel.crashing.org +60 -0 # This adds a function to use the residual data to determine the IRQ # for a given PCI device, and changes prep_pcibios_fixup() to use it. # # arch/ppc/platforms/prep_pci.c # 2004/08/16 10:35:09-07:00 trini@kernel.crashing.org +37 -23 # This adds a function to use the residual data to determine the IRQ # for a given PCI device, and changes prep_pcibios_fixup() to use it. Mmm, i guess this makes sense, since it seems the sym53c8xx doesn'y find its irq anymore or something. Tom Rini, or Leigh Brown, do you have any comments on this one ? Friendly, Sven Luther
