2012-12-18linux-user/syscall.c: remove wrong forward decl of setgroups()John Spencer1-1/+1
this declaration is wrong: the correct prototype on linux is: int setgroups(size_t size, const gid_t *list); since by default musl libc exposes this symbol in unistd.h additionally to grp.h, the wrong declaration causes a build error. the proper fix is to simply include the correct header.

2012-12-15target-xtensa: fix ITLB/DTLB page protection flagsMax Filippov1-1/+2
With MMU option xtensa architecture has two TLBs: ITLB and DTLB. ITLB is only used for code access, DTLB is only for data. However TLB entries in both TLBs have attribute field controlling write and exec access. These bits need to be properly masked off depending on TLB type before being used as tlb_set_page prot argument. Otherwise the following happens: (1) ITLB entry for some PFN gets invalidated (2) DTLB entry for the same PFN gets updated, attributes allow code execution (3) code at the page with that PFN is executed (possible due to step 2), entry for the TB is written into the jump cache (4) QEMU TLB entry for the PFN gets replaced with an entry for some other PFN (5) code in the TB from step 3 is executed (possible due to jump cache) and it accesses data, for which there's no DTLB entry, causing DTLB miss exception (6) re-translation of the TB from step 5 is attempted, but there's no QEMU TLB entry nor xtensa ITLB entry for that PFN, which causes ITLB miss exception at the TB start address (7) ITLB miss exception is handled by the guest, but execution is resumed from the beginning of the faulting TB (the point where ITLB miss occured), not from the point where DTLB miss occured, which is wrong. With that fix the above scenario causes ITLB miss exception (that used to be step 7) at step 3, right at the beginning of the TB.

This reverts commit 288fa40736e6eb63132d01aa6dc21ee831b796ae. The only reason old pixman versions didn't work was the missing PIXMAN_TYPE_BGRA, which is properly #ifdef'ed now.

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.

2012-12-14target-ppc: Don't use hwaddr to represent hardware stateDavid Gibson1-1/+1
The hwaddr type is somewhat vaguely defined as being able to contain bus addresses on the widest possible bus in the system. For that reason it's discouraged for representing specific pieces of persistent hardware state, which should instead use an explicit width type that matches the bits available in real hardware. In particular, because of the possibility that the size of hwaddr might change if different buses are added to the target in future, it's not suitable for use in vm state descriptions for savevm and migration. This patch purges such unwise uses of hwaddr from the ppc target code, which turns out to be just one. The ppcemb_tlb_t struct, used on a number of embedded ppc models to represent a TLB entry contains a hwaddr for the real address field. This patch changes it to be a fixed uint64_t which is suitable enough for all machine types which use this structure. Other uses of hwaddr in CPUPPCState turn out not to be problematic: htab_base and htab_mask are just used for the convenience of the TCG code; the underlying machine state is the SDR1 register, which is stored with a suitable type already. Likewise the mpic_cpu_base field is only used internally and does not represent fundamental hardware state which needs to be saved.

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>

2012-12-14MSI-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>

2012-12-14openpic: 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: 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: unify memory api subregionsAlexander Graf1-52/+56

2012-12-14openpic: Convert subregions to memory apiAlexander Graf1-45/+61

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.
