2012-10-05PPC: e500: Only expose even TLB sizes in initial TLBAlexander Graf1-0/+4
When booting our e500 machine, we automatically generate a big TLB entry in TLB1 that covers all of the code we need to run in there until the guest can handle its TLB on its own. However, e500v2 can only handle MAS1.0 sizes. However, we keep our TLB information in MAS2.0 layout, which means we have twice as many TLB sizes to choose from. That also means we can run into a situation where we try to add a TLB size that could not fit into the MAS1.0 size bits. Fix it by making sure we always have the lower bit set to 0. That way we are always guaranteed to have MAS1.0 compatible TLB size information. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-10-05PPC: e500: calculate initrd_base like dt_baseScott Wood1-1/+2
While investigating dtb pad issues, I noticed that initrd_base wasn't taking loadaddr into account the way dt_base was. This seems wrong. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-10-05PPC: e500: increase DTC_LOAD_PADScott Wood1-1/+1
An allowance of 5 MiB for BSS is not enough for Linux kernels with certain debug options enabled (not sure exactly which one caused it, but I'd guess lockdep). The kernel I ran into this with had a BSS of around 6.4 MB. Unfortunately, uImage does not give us enough information to determine the actual BSS size. Increase the allowance to 18 MiB to give us plenty of room. Eventually this should be more intelligent, possibly packing initrd+dtb at the end of guest RAM.

2012-10-05fdt: move dumpdtb interpretation code to device_tree.cAlexander Graf1-14/+1
The dumpdtb code can be useful in more places than just for e500. Move it to a generic place. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-08-15Revert "PPC: e500: Use new MPIC dt format"Alexander Graf1-17/+14
This reverts commit 518c7fb44f2182cde943dc64f88cb2fd4e4ff6b5. It breaks new Linux guests with SMP, because IPIs get mapped to large vectors which our MPIC emulation does not implement. Conflicts: hw/ppc/e500.c
2012-08-15PPC: e500: add generic e500 platformScott Wood2-1/+61
This gives the kernel a paravirtualized machine to target, without requiring both sides to pretend to be targeting a specific board that likely has little to do with the host in KVM scenarios. This avoids the need to add new boards to QEMU, just to be able to run KVM on new CPUs.

2012-08-15PPC: e500: split mpc8544ds machine from generic e500 codeScott Wood4-51/+114
Currently the only mpc8544ds-ism that is factored out is toplevel compatible and model. In the future the generic e500 code is expected to become more generic. Signed-off-by: Scott Wood <scottwood@freescale.com> [agraf: conditionalize on CONFIG_FDT] Signed-off-by: Alexander Graf <agraf@suse.de>
2012-08-15PPC: e500: change internal references away from mpc8544dsScott Wood1-13/+14
No functional changes -- machine is still outwardly mpc8544ds. The references that are not changed contain mpc8544 hardware details that need to be parameterized if/when a different e500 platform wants to change them.

2012-08-15PPC: e500: rename mpc8544ds into generic fileScott Wood2-1/+613
Rename the file (with no changes other than fixing up the header paths) in preparation for refactoring into a generic e500 platform. Also move it into the newly created ppc/ directory.

2012-06-27pseries: Convert sPAPR TCEs to use generic IOMMU infrastructureDavid Gibson1-1/+1
The pseries platform already contains an IOMMU implementation, since it is essential for the platform's paravirtualized VIO devices. This IOMMU support is currently built into the implementation of the VIO "bus" and the various VIO devices. This patch converts this code to make use of the new common IOMMU infrastructure. We don't yet handle synchronization of map/unmap callbacks vs. invalidations, this will require some complex interaction with the kernel and is not a major concern at this stage.

2012-06-24PPC: e500: require libfdtAlexander Graf1-1/+1
Now that we're moving all of the device tree generation from an external pre-execution generated blob to runtime generation using libfdt, we absolutely must have libfdt around. This requirement was there before already, as the only way to not require libfdt with e500 was to not use -kernel, which was the only way to boot the mpc8544ds machine. This patch only manifests said requirement in the build system. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-06-15hw/xilinx_*: Share Xilinx devices between ppc and microblazeAndreas Färber1-3/+0
Speeds up the build. xilinx_ethlite uses tswap32() and is thus target-dependent. Signed-off-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
