parisc: Fix exported address of os_hpmc handler

2018-10-17T06:18:01Z

In the C-code we need to put the physical address of the hpmc handler in the interrupt vector table (IVA) in order to get HPMCs working. Since on parisc64 function pointers are indirect (in fact they are function descriptors) we instead export the address as variable and not as function.

parisc: Fix HPMC handler by increasing size to multiple of 16 bytes

2018-03-27T16:52:22Z

Make sure that the HPMC (High Priority Machine Check) handler is 16-byte aligned and that it's length in the IVT is a multiple of 16 bytes. Otherwise PDC may decide not to call the HPMC crash handler. Signed-off-by: Helge Deller Cc: stable@vger.kernel.org

parisc: Align os_hpmc_size on word boundary

2017-12-17T20:06:25Z

The os_hpmc_size variable sometimes wasn't aligned at word boundary and thus triggered the unaligned fault handler at startup. Fix it by aligning it properly. Signed-off-by: Helge Deller Cc: # v4.14+

parisc: fix partly 16/64k PAGE_SIZE boot

2013-05-06T21:08:32Z

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
