Helge Deller 6a45716abb parisc: fix partly 16/64k PAGE_SIZE boot This patch fixes partly PAGE_SIZEs of 16K or 64K by adjusting the assembler PTE lookup code and the assembler TEMPALIAS code. Furthermore some data alignments for PAGE_SIZE have been limited to 4K (or less) to not waste too much memory with greater page sizes. As a side note, the palo loader can (currently) only handle up to 10 ELF segments which is fixed with tighter aligning as well. My testings indicated that the ldci command in the sba iommu coding needed adjustment by the PAGE_SHIFT value and that the I/O PDIR Page size was only set to 4K for my machine (C3000). All this fixes partly the boot, but there are still quite some caching problems left. Examples are e.g. the symbios logic driver which is failing: sym0: <896> rev 0x7 at pci 0000:00:0f.0 irq 69 sym0: PA-RISC Firmware, ID 7, Fast-40, SE, parity checking CACHE TEST FAILED: DMA error (dstat=0x81).sym0: CACHE INCORRECTLY CONFIGURED. and the tulip network driver which doesn't seem to work correctly either: Sending BOOTP requests .net eth0: Setting full-duplex based on MII#1 link partner capability of 05e1 ..... timed out! Beside those kernel fixes glibc will need fixes too to be able to handle >4K page sizes. Signed-off-by: Helge Deller <deller@gmx.de>		2013-05-06 23:08:32 +02:00

/*
** HP VISUALIZE Workstation PCI Bus Defect
**
** "HP has discovered a potential system defect that can affect
** the behavior of five models of HP VISUALIZE workstations when
** equipped with third-party or customer-installed PCI I/O expansion
** cards. The defect is limited to the HP C180, C160, C160L, B160L,
** and B132L VISUALIZE workstations, and will only be encountered
** when data is transmitted through PCI I/O expansion cards on the
** PCI bus. HP-supplied graphics cards that utilize the PCI bus are
** not affected."
