normally BIOSes assign io/mmio range to different HT links without overlapping, even same node same link should get non overlapping entries. but Rafael L. Wysocki's buggy BIOS creates a link with overlapping entries for mmio and io: node 0 link 0: io port [1000, ffffff] node 0 link 0: mmio [e0000000, efffffff] node 0 link 0: mmio [a0000, bffff] node 0 link 0: mmio [80000000, ffffffff] try to merge them and we will get: bus: [00, ff] on node 0 link 0 bus: 00 index 0 io port: [0, ffff] bus: 00 index 1 mmio: [80000000, fcffffffff] bus: 00 index 2 mmio: [a0000, bffff] so later we will reduce the chance to assign used resource to unassigned device.

some bioses give same range to mmconf for fam10h msr, and mmio for node/link. fam10h msr will overide mmio for node/link. so we can not assign range to devices under node/link for unassigned resources. this patch will take range out from the mmio for node/link Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

scan AMD opteron io/mmio routing to make sure every pci root bus get correct resource range. Thus later pci scan could assign correct resource to device with unassigned resource. this can fix a system without _CRS for multi pci root bus.

Currently, on an amd k8 system with multi ht chains, the numa_node of pci devices under /sys/devices/pci0000:80/* is always 0, even if that chain is on node 1 or 2 or 3. Workaround: pcibus_to_node(bus) is used when we want to get the node that pci_device is on. In struct device, we already have numa_node member, and we could use dev_to_node()/set_dev_node() to get and set numa_node in the device. set_dev_node is called in pci_device_add() with pcibus_to_node(bus), and pcibus_to_node uses bus->sysdata for nodeid. The problem is when pci_add_device is called, bus->sysdata is not assigned correct nodeid yet. The result is that numa_node will always be 0. pcibios_scan_root and pci_scan_root could take sysdata. So we need to get mp_bus_to_node mapping before these two are called, and thus get_mp_bus_to_node could get correct node for sysdata in root bus. In scanning of the root bus, all child busses will take parent bus sysdata. So all pci_device->dev.numa_node will be assigned correctly and automatically. Later we could use dev_to_node(&pci_dev->dev) to get numa_node, and we could also could make other bus specific device get the correct numa_node too. This is an updated version of pci_sysdata and Jeff's pci_domain patch.

some BIOS only let AMD fam 10h handle bus0, and nvidia mcp55/ck804 to handle other buses. at that case MCFG will cover all over them. but with acpi=off, we can not use MCFG. this patch will double check the busnbits, and if it is less handling 256 bues, and acpi=off will forcely reset the mmconf in msr, so we still use mmconf in above case.

Patch "x86: validate against ACPI motherboard resources" changed the mmconf init sequence, and init MMCONF late in acpi_init. here change it back to old sequence: 1. check hostbridge in early 2. check MCFG with e820 in early 3. if all fail, will check MCFg with acpi _CRS in acpi_init So we can make MCONF working again when acpi=off is set if hostbridge support that.

This path adds validation of the MMCONFIG table against the ACPI reserved motherboard resources. If the MMCONFIG table is found to be reserved in ACPI, we don't bother checking the E820 table. The PCI Express firmware spec apparently tells BIOS developers that reservation in ACPI is required and E820 reservation is optional, so checking against ACPI first makes sense. Many BIOSes don't reserve the MMCONFIG region in E820 even though it is perfectly functional, the existing check needlessly disables MMCONFIG in these cases. In order to do this, MMCONFIG setup has been split into two phases. If PCI configuration type 1 is not available then MMCONFIG is enabled early as before. Otherwise, it is enabled later after the ACPI interpreter is enabled, since we need to be able to execute control methods in order to check the ACPI reserved resources. Presently this is just triggered off the end of ACPI interpreter initialization. There are a few other behavioral changes here: - Validate all MMCONFIG configurations provided, not just the first one. - Validate the entire required length of each configuration according to the provided ending bus number is reserved, not just the minimum required allocation. - Validate that the area is reserved even if we read it from the chipset directly and not from the MCFG table. This catches the case where the BIOS didn't set the location properly in the chipset and has mapped it over other things it shouldn't have. This also cleans up the MMCONFIG initialization functions so that they simply do nothing if MMCONFIG is not compiled in. Based on an original patch by Rajesh Shah from Intel.

typical case: four sockets system, every node has 4g ram, and we are using: memmap=10g$4g to mask out memory on node1 and node2 when numa is enabled, early_node_mem is used to get node_data and node_bootmap. if it can not get memory from the same node with find_e820_area(), it will use alloc_bootmem to get buff from previous nodes. so check it and print out some info about it. need to move early_res_to_bootmem into every setup_node_bootmem. and it takes range that node has. otherwise alloc_bootmem could return addr that reserved early. depends on "mm: make reserve_bootmem can crossed the nodes".

vmemmap allocation currently has this layout: [ffffe20000000000-ffffe200001fffff] PMD ->ffff810001400000 on node 0 [ffffe20000200000-ffffe200003fffff] PMD ->ffff810001800000 on node 0 [ffffe20000400000-ffffe200005fffff] PMD ->ffff810001c00000 on node 0 [ffffe20000600000-ffffe200007fffff] PMD ->ffff810002000000 on node 0 [ffffe20000800000-ffffe200009fffff] PMD ->ffff810002400000 on node 0 ... note that there is a 2M hole between them - not optimal. the root cause is that usemap (24 bytes) will be allocated after every 2M mem_map, and it will push next vmemmap (2M) to the next (2M) alignment. solution: try to allocate the mem_map continously. after the patch, we get: [ffffe20000000000-ffffe200001fffff] PMD ->ffff810001400000 on node 0 [ffffe20000200000-ffffe200003fffff] PMD ->ffff810001600000 on node 0 [ffffe20000400000-ffffe200005fffff] PMD ->ffff810001800000 on node 0 [ffffe20000600000-ffffe200007fffff] PMD ->ffff810001a00000 on node 0 [ffffe20000800000-ffffe200009fffff] PMD ->ffff810001c00000 on node 0 ... which is the ideal layout. and usemap will share a page because of they are allocated continuously too: sparse_early_usemap_alloc: usemap = ffff810024e00000 size = 24 sparse_early_usemap_alloc: usemap = ffff810024e00080 size = 24 sparse_early_usemap_alloc: usemap = ffff810024e00100 size = 24 sparse_early_usemap_alloc: usemap = ffff810024e00180 size = 24 ... so we make the bootmem allocation more compact and use less memory for usemap => mission accomplished ;-) Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
