2012-06-24PPC: e500: dt: use target_phys_addr_t for ramsizeAlexander Graf
We're passing the ram size as uint32_t, capping it to 32 bits atm. Change to target_phys_addr_t (uint64_t) to make sure we have all the bits. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-06-24PPC: e500: dt: use 64bit cell helperAlexander Graf
We have a nice 64bit helper to ease the device tree generation and make the code more readable when creating 64bit 2-cell parameters. Use it when generating the device tree. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-06-24dt: Add -machine dumpdtb option to dump the current dtbAlexander Graf
Now that we are dynamically creating the dtb, it's really useful to be able to dump the created blob for debugging. This patch implements a -machine dumpdtb=<file> option for e500 that dumps the dtb exactly in the form the guest would get it to disk. It can then be analyzed by dtc to get information about the guest configuration. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-06-24PPC: e500: dt: start with empty device treeAlexander Graf
Now that all of the device tree bits are generated during runtime, we can get rid of the device tree blob and instead start from scratch with an empty device tree. Signed-off-by: Alexander Graf <agraf@suse.de>

2012-06-24PPC: e500: require libfdtAlexander Graf
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>
2012-06-24spapr: Add "memop" hypercallBenjamin Herrenschmidt
This adds a qemu-specific hypervisor call to the pseries machine which allows to do what amounts to memmove, memcpy and xor over regions of physical memory such as the framebuffer. This is the simplest way to get usable framebuffer speed from SLOF since the framebuffer isn't mapped in the VRMA and so would otherwise require an hcall per 8 bytes access. The performance is still not great but usable, and can be improved with a more complex implementation of the hcall itself if needed. This also adds some documentation for the qemu-specific hypercalls that we add to PAPR along with a new qemu,hypertas-functions property that mirrors ibm,hypertas-functions and provides some discoverability for the new calls. Note: I chose note to advertise H_RTAS to the guest via that mechanism. This is done on purpose, the guest uses the normal RTAS interfaces provided by qemu (including SLOF) which internally calls H_RTAS. We might in the future implement part (or even all) of RTAS inside the guest like IBM's firmware does and replace H_RTAS with some finer grained set of private hypercalls.

2012-06-24spapr_vscsi: Error handling fixesBenjamin Herrenschmidt

2012-06-24pseries: Correctly create ibm,segment-page-sizes propertyBenjamin Herrenschmidt
The core tcg/kvm code for ppc64 now has at least the outline capability to support pagesizes beyond the standard 4k and 16MB. The CPUState is initialized with information advertising the available pagesizes and their correct encodings, and under the right KVM setup this will be populated with page sizes beyond the standard. Obviously guests can't use the extra page sizes unless they know they're present. For the pseries machine, at least, there is a defined method for conveying exactly this information, the "ibm-segment-page-sizes" property in the guest device tree. This patch generates this property using the supported page size information that's already in the CPUState.

2012-06-24PPC: mpc8544ds: Span initial TLB entry over as much RAM as we needAlexander Graf
The initial TLB entry is supposed to help us run the guest -kernel payload. This means the guest needs to be able to access its own memory, the initrd memory and the device tree. So far we only statically reserved a TLB entry from [0;256M[. This patch fixes it to span from [0;dt_end[, allowing the guest payload to access everything initially.

2012-06-22vga: make vram size configurableGerd Hoffmann
Zap the global VGA_RAM_SIZE #define, make the vga ram size configurable for standard vga and vmware vga. cirrus and qxl are left with a fixed size (and private VGA_RAM_SIZE #define) for now. qxl needs some non-trivial adjustments in the mode list handling deal with a runtime-configurable size, which calls for a separate qxl patch. cirrus emulates cards which have 2 MB (isa) and 4 MB (pci), so I guess it would make sense to use these sizes. That change would break migration though, so I left it fixed at 8 MB size. Making it configurabls is pretty pointless for cirrus as we have to match real hardware.

2012-06-22vga: raise xres+yres limitsGerd Hoffmann
The vgabios will check whenever any given video mode will fit into the given video memory before adding it to the list of available modes, so there is no need to keep xmax * ymax * 32bpp lower than VGA_RAM_SIZE. Lets raise the limits a bit. Should be good for a few years, display sizes are not growing that fast. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-06-21xilinx_timer: Fixed deadlock issuePeter A. G. Crosthwaite
The timer was deadlocking when the interval was set too low. It would cause a flood of timer events and the CPU would halt indefinately. This is a known issue and theres a generic workaround in place in ptimer on ptimer_set_limit(), however the Xilinx timer uses ptimer_set_count() instead of set_limit. Changed the call to set_count() to an equivalent call of set_limit() instead, which brings the workaround into play. Signed-off-by: Peter A. G.
