2019-06-12spapr: Clean up DRC index constructionDavid Gibson1-56/+68
spapr_pci.c currently has several confusingly similarly named functions for various conversions between representations of DRCs. Make things clearer by renaming things in a more consistent XXX_from_YYY() manner and remove some called-only-once variants in favour of open coding. While we're at it, move this code together in the file to avoid some extra forward references, and split out construction and removal of DRCs for the host bridge into helper functions.

2019-06-12spapr: Clean up spapr_drc_populate_dt()David Gibson4-15/+11
This makes some minor cleanups to spapr_drc_populate_dt(), renaming it to the shorter and more idiomatic spapr_dt_drc() along the way. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Reviewed-by: Greg Kurz <groug@kaod.org> Acked-by: Michael S. Tsirkin <mst@redhat.com>
2019-06-12spapr: Clean up dt creation for PCI busesDavid Gibson3-72/+79
Device nodes for PCI bridges (both host and P2P) describe both the bridge device itself and the bus hanging off it, handling of this is a bit of a mess. spapr_dt_pci_device() has a few things it only adds for non-bridges, but always adds #address-cells and #size-cells which should only appear for bridges. But the walking down the subordinate PCI bus is done in one of its callers spapr_populate_pci_devices_dt(). The PHB dt creation in spapr_populate_pci_dt() open codes some similar logic to the bridge case. This patch consolidates things in a bunch of ways: * Bus specific dt info is now created in spapr_dt_pci_bus() used for both P2P bridges and the host bridge. This includes walking subordinate devices * spapr_dt_pci_device() now calls spapr_dt_pci_bus() when called on a P2P bridge * We do detection of bridges with the is_bridge field of the device class, rather than checking PCI config space directly, for consistency with qemu's core PCI code. * Several things are renamed for brevity and clarity Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Acked-by: Michael S.

2019-06-12spapr: Clean up device tree construction for PCI devicesDavid Gibson1-64/+55
spapr_create_pci_child_dt() is a trivial wrapper around spapr_populate_pci_child_dt(), but is the latter's only caller. So fold them together into spapr_dt_pci_device(), which closer matches our modern naming convention. While there, make a number of cleanups to the function itself. This is mostly using more temporary locals to avoid awkwardly long lines, and in some cases avoiding double reads of PCI config space variables.

2019-06-12spapr: Clean up device node name generation for PCI devicesDavid Gibson1-25/+16
spapr_populate_pci_child_dt() adds a 'name' property to the device tree node for PCI devices. This is never necessary for a flattened device tree, it is implicit in the name added when the node is constructed. In fact anything we do add to a 'name' property will be overwritten with something derived from the structural name in the guest firmware (but in fact it is exactly the same bytes). So, remove that. In addition, pci_get_node_name() is very simple, so fold it into its (also simple) sole caller spapr_create_pci_child_dt(). While we're there rename pci_find_device_name() to the shorter and more accurate dt_name_from_class().

2019-06-12spapr_pci: Improve error messageGreg Kurz1-1/+8
Every PHB must have a unique index. This is checked at realize but when a duplicate index is detected, an error message mentioning BUIDs is printed. This doesn't help much, especially since BUID is an internal concept that is no longer exposed to the user. Fix the message to mention the index property instead of BUID. As a bonus print a list of indexes already in use.

2019-06-10tcg: Create struct CPUTLBRichard Henderson12-162/+145
Move all softmmu tlb data into this structure. Arrange the members so that we are able to place mask+table together and at a smaller absolute offset from ENV.

2019-06-10tcg: Split out target/arch/cpu-param.hRichard Henderson45-333/+544
For all targets, into this new file move TARGET_LONG_BITS, TARGET_PAGE_BITS, TARGET_PHYS_ADDR_SPACE_BITS, TARGET_VIRT_ADDR_SPACE_BITS, and NB_MMU_MODES. Include this new file from exec/cpu-defs.h. This now removes the somewhat odd requirement that target/arch/cpu.h defines TARGET_LONG_BITS before including exec/cpu-defs.h, so push the bulk of the includes within target/arch/cpu.h to the top.
