2012-12-19janitor: add guards to headersPaolo Bonzini27-0/+127
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-12-19ui: move files to ui/ and include/ui/Paolo Bonzini53-127/+70
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-12-19net: reorganize headersPaolo Bonzini72-98/+71
Move public headers to include/net, and leave private headers in net/. Put the virtio headers in include/net/tap.h, removing the multiple copies that existed. Leave include/net/tap.h as the interface for NICs, and net/tap_int.h as the interface for OS-specific parts of the tap backend. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-12-19janitor: do not include qemu-char everywherePaolo Bonzini9-7/+3
Touching char/char.h basically causes the whole of QEMU to be rebuilt. Avoid this, it is usually unnecessary. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-12-19janitor: do not rely on indirect inclusions of or from qemu-char.hPaolo Bonzini13-0/+14
Various header files rely on qemu-char.h including qemu-config.h or main-loop.h, but they really do not need qemu-char.h at all (particularly interesting is the case of the block layer!). Clean this up, and also add missing inclusions of qemu-char.h itself. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-12-17pci_bus.h: tweak include guardsMichael S. Tsirkin1-3/+3
Now that header has been renamed, tweak include guards to match. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2012-12-17pci_bus: update commentMichael S. Tsirkin1-7/+3
Don't ask everyone to desist from including this header, simply recommend using accessors. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2012-12-17pci: rename pci_internals.h pci_bus.hMichael S. Tsirkin13-12/+12
There are lots of external users of pci_internals.h, apparently making it an internal interface only didn't work out. Let's stop pretending it's an internal header. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2012-12-17Revert "pci: prepare makefiles for pci code reorganization"Michael S. Tsirkin1-1/+0
This reverts commit 475d67c3bcd6ba9fef917b6e59d96ae69eb1a9b4. Now that all users have been updated, we don't need the makefile hack or the softlink anymore. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2012-12-17pci: fix path for local includesMichael S. Tsirkin22-62/+62
Include dependencies from pci core using the correct path. This is required now that it's in the separate directory. Need to check whether they can be minimized, for now, keep the code as is. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2012-12-17pci: update all users to look in pci/Michael S. Tsirkin96-153/+153

2012-12-14pixman: fix vnc tight png/jpeg supportGerd Hoffmann1-1/+1
This patch adds an x argument to qemu_pixman_linebuf_fill so it can also be used to convert a partial scanline. Then fix tight + png/jpeg encoding by passing in the x+y offset, so the data is read from the correct screen location instead of the upper left corner.

2012-12-14pseries: Increase default NVRAM sizeDavid Gibson1-1/+1
If no image file for NVRAM is specified, the pseries machine currently creates a 16K non-persistent NVRAM by default. This basically works, but is not large enough for current firmware and guest kernels to create all the NVRAM partitions they would like to. Increasing the default size to 64K addresses this and stops the guest generating error messages.

2012-12-14PPC: e500: pci: Export slot2irq calculationAlexander Graf3-2/+15
We need the calculation method to get from a PCI slot ID to its respective interrupt line twice. Once in the internal map function and once when assembling the device tree. So let's extract the calculation to a separate function that can be called by both users. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14PPC: E500plat: Make a lot of PCI slots availableAlexander Graf1-2/+3
The ppce500 machine doesn't have to stick to hardware limitations, as it's defined as being fully device tree based. Thus we can change the initial PCI slot ID to 0x1 which gives us a whopping 31 PCI devices we can support with this machine now! Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14PPC: E500: Move PCI slot information into paramsAlexander Graf4-1/+9
We have a params struct that allows us to expose differences between e500 machine models. Include PCI slot information there, so we can have different machines with different PCI slot topology. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14PPC: E500: Generate dt pci irq map dynamicallyAlexander Graf1-20/+31
Today we're hardcoding the PCI interrupt map in the e500 machine file. Instead, let's write it dynamically so that different machine types can have different slot properties. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14PPC: E500: PCI: Make IRQ calculation more genericAlexander Graf1-10/+3
The IRQ line calculation is more or less hardcoded today. Instead, let's write it as an algorithmic function that theoretically allows an arbitrary number of PCI slots. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14PPC: E500: PCI: Make first slot qdev settableAlexander Graf1-1/+8
Today the first slot id in our e500 pci implementation is hardcoded to 0x11. Keep it there as default, but allow users to change the default to a different id. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: Accelerate pending irq searchAlexander Graf1-0/+11
When we're done with one interrupt, we need to search for the next pending interrupt in the queue. This search has grown quite big now that we have more than 256 possible irq lines. So let's memorize how many interrupts we have pending in our bitmaps, so that we can always bail out in the usual case - the one where we're all done. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: fix minor coding style issuesAlexander Graf1-6/+6
This patch removes all remaining occurences of spaces before function parameter indicating parenthesis. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14MSI-X: Fix endiannessAlexander Graf1-4/+2
The MSI-X vector tables are usually stored in little endian in memory, so let's mark the accessors as such. This fixes MSI-X on e500 for me. Signed-off-by: Alexander Graf <agraf@suse.de> Acked-by: Michael S. Tsirkin <mst@redhat.com>
2012-12-14PPC: e500: Declare pci bridge as bridgeAlexander Graf1-0/+6
The new PCI host bridge device needs to identify itself as PCI host bridge. Declare it as such. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14PPC: e500: Add MSI supportAlexander Graf1-0/+23
Now that our interrupt controller supports MSIs, let's expose that feature to the guest through the device tree! Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: add Shared MSI supportAlexander Graf1-20/+130
The OpenPIC allows MSI access through shared MSI registers. Implement them for the MPC8544 MPIC, so we can support MSIs. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: make brr1 model specificAlexander Graf1-1/+4
Now that we can properly distinguish between openpic model differences, let's move brr1 out of the raven code path. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: convert to qdevAlexander Graf4-155/+180
This patch converts the OpenPIC device to qdev. Along the way it renames the "openpic" target to "raven" and the "mpic" target to "fsl_mpic_20", to better reflect the actual models they implement. This way we have a generic OpenPIC device now that can handle different flavors of the OpenPIC specification. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: remove irq_outAlexander Graf4-10/+6
The current openpic emulation contains half-ready code for bypass mode. Remove it, so that when someone wants to finish it they can start from a clean state. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: rename openpic_t to OpenPICStateAlexander Graf1-34/+34
Rename the openpic_t struct to OpenPICState, so it adheres better to the current coding style rules. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: convert simple reg operations to builtin bitopsAlexander Graf1-31/+36
The openpic code has its own bitmap code to access bits inside of a bitmap. However, that is overkill when we simply want to check for a bit inside of a uint32_t. So instead, let's use normal bit masks and C builtin shifts and ands. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: remove unused type variableAlexander Graf1-25/+2
The openpic source irqs are carrying around a type indicator that is never accessed by anything. Remove it. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: unify memory api subregionsAlexander Graf1-52/+56
The only difference between the "openpic" and "mpic" memory api subregion descriptors is the endianness. Unify them as openpic accessors with explicit endianness markers in their names. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: combine openpic and mpic reset functionsAlexander Graf1-61/+42
The openpic and mpic reset handlers are almost identical. Combine them and extract the differences into state variables. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: merge mpic and openpic timer handlingAlexander Graf1-100/+31
The openpic and mpic timer handling code is basically the same. Merge them. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: combine mpic and openpic irq raise functionsAlexander Graf2-18/+19
The IRQ raise mechanisms of the OpenPIC and MPIC controllers is identical, just that the MPIC one can also raise critical interrupts. Combine those two and check for critical raise capability during runtime. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: Convert subregions to memory apiAlexander Graf1-45/+61
The "openpic" controller is currently using one big region and does subregion dispatching manually. Move this to the memory api. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: combine mpic and openpic src handlersAlexander Graf1-47/+5
The MPIC source irq handler suddenly became identical to the standard OpenPIC source irq handler. Combine them into the same function. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: update to proper memory apiAlexander Graf1-90/+48
The openpic code was still using the old mmio memory api. Convert it to be a generic memory api user and clean up some code that becomes redundant that way. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14mpic: Unify numbering schemeAlexander Graf2-249/+45
MPIC interrupt numbers in Linux (device tree) and in QEMU are different, because QEMU takes the sparseness of the IRQ number space into account. Remove that cleverness and instead assume a flat number space. This makes the code easier to understand, because we are actually aligned with Linux on the view of our worlds. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14openpic: Remove unused codeAlexander Graf1-163/+0
The openpic code had a few WIP bits left that nobody reanimated within the last few years. Remove that code. Signed-off-by: Alexander Graf <agraf@suse.de> Acked-by: Hervé Poussineau <hpoussin@reactos.org>
2012-12-14pseries: Don't allow TCE (iommu) tables to be registered with duplicate LIOBNsDavid Gibson1-0/+6
The PAPR specification requires that every bus or device mediated by the IOMMU have a unique Logical IO Bus Number (LIOBN). This patch adds a check to enforce this, which will help catch errors in configuration earlier. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-12-14Adding BAR0 for e500 PCI controllerBharat Bhushan3-10/+91
PCI Root complex have TYPE-1 configuration header while PCI endpoint have type-0 configuration header. The type-1 configuration header have a BAR (BAR0). In Freescale PCI controller BAR0 is used for mapping pci address space to CCSR address space. This can used for 2 purposes: 1) for MSI interrupt generation 2) Allow CCSR registers access when configured as PCI endpoint, which I am not sure is a use case with QEMU-KVM guest. What I observed is that when guest read the size of BAR0 of host controller configuration header (TYPE1 header) then it always reads it as 0. When looking into the QEMU hw/ppce500_pci.c, I do not find the PCI controller device registering BAR0. I do not find any other controller also doing so may they do not use BAR0. There are two issues when BAR0 is not there (which I can think of): 1) There should be BAR0 emulated for PCI Root complex (TYPE1 header) and when reading the size of BAR0, it should give size as per real h/w. 2) Do we need this BAR0 inbound address translation? When BAR0 is of non-zero size then it will be configured for PCI address space to local address(CCSR) space translation on inbound access. The primary use case is for MSI interrupt generation. The device is configured with an address offsets in PCI address space, which will be translated to MSI interrupt generation MPIC registers. Currently I do not understand the MSI interrupt generation mechanism in QEMU and also IIRC we do not use QEMU MSI interrupt mechanism on e500 guest machines. But this BAR0 will be used when using MSI on e500. I can see one more issue, There are ATMUs emulated in hw/ppce500_pci.c, but i do not see these being used for address translation. So far that works because pci address space and local address space are 1:1 mapped. BAR0 inbound translation + ATMU translation will complete the address translation of inbound traffic.
