The function sba_alloc_range is called with size 0x11000, thus the pages_needed variable is 0x11. The function sba_search_bitmap is called with bits_wanted 0x11 and boundary size is 0x10 (because dma_get_seg_boundary(dev) returns 0xffff). The function sba_search_bitmap attempts to allocate 17 pages that must not cross 16-page boundary - it can't satisfy this requirement (iommu_is_span_boundary always returns true) and fails even if there are many free entries in the IOMMU space. How did it happen that we try to allocate 17 pages that don't cross 16-page boundary? The cause is in the function iommu_coalesce_chunks. This function tries to coalesce adjacent entries in the scatterlist. The function does several checks if it may coalesce one entry with the next, one of those checks is this: if (startsg->length + dma_len > max_seg_size) break; When it finishes coalescing adjacent entries, it allocates the mapping: sg_dma_len(contig_sg) = dma_len; dma_len = ALIGN(dma_len + dma_offset, IOVP_SIZE); sg_dma_address(contig_sg) = PIDE_FLAG | (iommu_alloc_range(ioc, dev, dma_len) << IOVP_SHIFT) | dma_offset; It is possible that (startsg->length + dma_len > max_seg_size) is false (we are just near the 0x10000 max_seg_size boundary), so the funcion decides to coalesce this entry with the next entry. When the coalescing succeeds, the function performs dma_len = ALIGN(dma_len + dma_offset, IOVP_SIZE); And now, because of non-zero dma_offset, dma_len is greater than 0x10000. iommu_alloc_range (a pointer to sba_alloc_range) is called and it attempts to allocate 17 pages for a device that must not cross 16-page boundary. To fix the bug, we must make sure that dma_len after addition of dma_offset and alignment doesn't cross the segment boundary. I.e. change if (startsg->length + dma_len > max_seg_size) break; to if (ALIGN(dma_len + dma_offset + startsg->length, IOVP_SIZE) > max_seg_size) break; This patch makes this change (it precalculates max_seg_boundary at the beginning of the function iommu_coalesce_chunks). I also added a check that the mapping length doesn't exceed dma_get_seg_boundary(dev) (it is not needed for Promise TX2+ SATA, but it may be needed for other devices that have dma_get_seg_boundary lower than dma_get_max_seg_size).

* PCI: Revert "PCI: Call pci_read_bridge_bases() from core instead of arch code"Bjorn Helgaas2015-09-152-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert dff22d2054b5 ("PCI: Call pci_read_bridge_bases() from core instead of arch code"). Reading PCI bridge windows is not arch-specific in itself, but there is PCI core code that doesn't work correctly if we read them too early. For example, Hannes found this case on an ARM Freescale i.mx6 board: pci_bus 0000:00: root bus resource [mem 0x01000000-0x01efffff] pci 0000:00:00.0: PCI bridge to [bus 01-ff] pci 0000:00:00.0: BAR 8: no space for [mem size 0x01000000] (mem window) pci 0000:01:00.0: BAR 2: failed to assign [mem size 0x00200000] pci 0000:01:00.0: BAR 1: failed to assign [mem size 0x00004000] pci 0000:01:00.0: BAR 0: failed to assign [mem size 0x00000100] The 00:00.0 mem window needs to be at least 3MB: the 01:00.0 device needs 0x204100 of space, and mem windows are megabyte-aligned. Bus sizing can increase a bridge window size, but never *decrease* it (see d65245c3297a ("PCI: don't shrink bridge resources")). Prior to dff22d2054b5, ARM didn't read bridge windows at all, so the "original size" was zero, and we assigned a 3MB window. After dff22d2054b5, we read the bridge windows before sizing the bus. The firmware programmed a 16MB window (size 0x01000000) in 00:00.0, and since we never decrease the size, we kept 16MB even though we only needed 3MB. But 16MB doesn't fit in the host bridge aperture, so we failed to assign space for the window and the downstream devices. I think this is a defect in the PCI core: we shouldn't rely on the firmware to assign sensible windows. Ray reported a similar problem, also on ARM, with Broadcom iProc. Issues like this are too hard to fix right now, so revert dff22d2054b5.

* PCI,parisc: Enable 64-bit bus addresses on PA-RISCHelge Deller2015-09-081-2/+5
| | | | | | | | | | | | | | | | | | | Commit 3a9ad0b ("PCI: Add pci_bus_addr_t") unconditionally introduced usage of 64-bit PCI bus addresses on all 64-bit platforms which broke PA-RISC. It turned out that due to enabling the 64-bit addresses, the PCI logic decided to use the GMMIO instead of the LMMIO region. This commit simply disables registering the GMMIO and thus we fall back to use the LMMIO region as before.

* | PCI: Call pci_read_bridge_bases() from core instead of arch codeLorenzo Pieralisi2015-07-232-4/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we scan a PCI bus, we read PCI-PCI bridge window registers with pci_read_bridge_bases() so we can validate the resource hierarchy. Most architectures call pci_read_bridge_bases() from pcibios_fixup_bus(), but PCI-PCI bridges are not arch-specific, so this doesn't need to be in arch-specific code. Call pci_read_bridge_bases() directly from the PCI core instead of from arch code. For alpha and mips, we now call pci_read_bridge_bases() always; previously we only called it if PCI_PROBE_ONLY was set.

| * PCI: Delay enabling bridges until they're neededYinghai Lu2013-07-251-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | We currently enable PCI bridges after scanning a bus and assigning resources. This is often done in arch code. This patch changes this so we don't enable a bridge until necessary, i.e., until we enable a PCI device behind the bridge. We do this in the generic pci_enable_device() path, so this also removes the arch-specific code to enable bridges.

* | parisc: Fix interrupt routing for C8000 serial portsThomas Bogendoerfer2013-07-311-11/+27
|/ | | | | | | | | | | | | | We can't use dev->mod_index for selecting the interrupt routing entry, because it's not an index into interrupt routing table. It will be even wrong on a machine with 2 CPUs (4 cores). But all needed information is contained in the PAT entries for the serial ports. mod[0] contains the iosapic address and mod_info has some indications for the interrupt input (at least it looks like it). This patch implements the searching for the right iosapic and uses this interrupt input information.

This fixes the problem of "early" and "header" quirks seeing incorrect root bus resources. added tests for elmmio_space.start while it should use elmmio_space.flags.

* parisc: fix partly 16/64k PAGE_SIZE bootHelge Deller2013-05-061-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

Therefore, simply mandate that _ALL_ IRQ handlers are run with IRQs disabled. [ This _should_ not break anything, since we've mandated that IRQ handlers _must_ be able to deal with this for a _long_ time ] IRQ handlers should be fast, no if buts and any other exceptions.
