2013-07-11PPC: dbdma: Move static bh variable to device structAlexander Graf
The DBDMA controller has a bottom half to asynchronously process DMA request queues. This bh was stored as a gross static variable. Move it into the device struct instead. While at it, move all users of it to the new generic kick function. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-11PPC: dbdma: Introduce kick functionAlexander Graf
The DBDMA engine really is running all the time, waiting for input. However we don't want to waste cycles constantly polling. So introduce a kick function that data providers can call to notify the DBDMA controller of new input. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-11PPC: dbdma: Move defines into header fileAlexander Graf
We usually keep struct and constant definitions in header files. Move them there to stay consistent and to make access to fields easier. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-11PPC: dbdma: Allow new commands in RUN stateAlexander Graf
The DBDMA controller can not change its command stream while it's actively streaming data, true. But the fact that it's in RUN state doesn't actually indicate anything. It could just as well be in WAIT while in RUN. And then it's legal to change commands. This fixes a real world issue I've encountered with Mac OS X. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-11PPC: dbdma: Fix debug printAlexander Graf
There was a debug print that didn't compile for me because the format and the arguments weren't in sync. Fix it up. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-11PPC: Mac: Add debug prints in macio and dbdma codeAlexander Graf
The macio code is basically undebuggable as it stands today, with no debug prints anywhere whatsoever. DBDMA was better, but I needed a few more to create reasonable logs that tell me where breakage is. Add a DPRINTF macro in the macio source file and add a bunch of debug prints that are all disabled by default of course. Signed-off-by: Alexander Graf <agraf@suse.de>

2013-07-11PPC: g3beige: Move secondary IDE bus to mac-ioAlexander Graf
On a real G3 Beige the secondary IDE bus lives on the mac-io chip, not on some random PCI device. Move it there to become more compatible. While at it, also clean up the IDE channel connection logic. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-11PPC: Mac: Fix guest exported tbfreq valuesAlexander Graf
We can tell the guest the frequency of its time base through fwcfg. However, we tell it a different value from the speed tb actually runs at. Let's fix it and make the tbfreq initialization and the fwcfg exposure use the same values. Signed-off-by: Alexander Graf <agraf@suse.de>

2013-07-11spapr: Use named enum for function remove_hpteStefan Weil
The function returned a target_ulong which was made from unnamed enum values. The target_ulong was then assigned to an int variable which was used in a switch statement. Using a named enum in both cases makes reviews easier. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-11spapr: Fix compiler warnings for some versions of gccStefan Weil
i686-w64-mingw32-gcc (GCC) 4.6.3 from Debian wheezy reports these warnings: hw/ppc/spapr_hcall.c:188:1: warning: control reaches end of non-void function [-Wreturn-type] hw/ppc/spapr_pci.c:454:1: warning: control reaches end of non-void function [-Wreturn-type] Both warnings are fixed by using g_assert_not_reached instead of assert. A second line with assert(0) in spapr_pci.c which did not raise a compiler warning was modified, too, because g_assert_not_reached documents the purpose of that statement and is not removed in release builds.

2013-07-11e600 core for MPC86xx processorsJulio Guerra
MPC86xx processors are based on the e600 core, which is not the case in qemu where it is based on the 7400 processor. This patch creates the e600 core and instantiates the MPC86xx processors based on it. Therefore, adding the high BATs, the SPRG 4..7 registers, which are e600-specific [1], and a HW MMU model (as 7400). This allows to define the MPC8610 processor too. Tested with a kernel using the HW TLB misses.

2013-07-10add timestamp to error_report()Seiji Aguchi
[Issue] When we offer a customer support service and a problem happens in a customer's system, we try to understand the problem by comparing what the customer reports with message logs of the customer's system. In this case, we often need to know when the problem happens. But, currently, there is no timestamp in qemu's error messages. Therefore, we may not be able to understand the problem based on error messages. [Solution] Add a timestamp to qemu's error message logged by error_report() with g_time_val_to_iso8601().

2013-07-10qapi.py: Allow top-level type reference for command definitionsKevin Wolf
If 'data' for a command definition isn't a dict, but a string, it is taken as a (struct) type name and the fields of this struct are directly used as parameters. This is useful for transactionable commands that can use the same type definition for both the transaction action and the arguments of the standalone command.

Add documentation and make the functions available through qemu/log.h outside NEED_CPU_H to allow use in qom/cpu.c.
