2019-03-05hw/arm/virt: Implement kvm_type function for 4.0 machineEric Auger
This patch implements the machine class kvm_type() callback. It returns the number of bits requested to implement the whole GPA range including the RAM and IO regions located beyond. The returned value is passed though the KVM_CREATE_VM ioctl and this allows KVM to set the stage2 tables dynamically. To compute the highest GPA used in the memory map, kvm_type() must freeze the memory map by calling virt_set_memmap().

2019-03-05hw/arm/virt: Dynamic memory map depending on RAM requirementsEric Auger
Up to now the memory map has been static and the high IO region base has always been 256GiB. This patch modifies the virt_set_memmap() function, which freezes the memory map, so that the high IO range base becomes floating, located after the initial RAM and the device memory. The function computes - the base of the device memory, - the size of the device memory, - the high IO region base - the highest GPA used in the memory map. Entries of the high IO region are assigned a base address. The device memory is initialized. The highest GPA used in the memory map will be used at VM creation to choose the requested IPA size. Setting all the existing highmem IO regions beyond the RAM allows to have a single contiguous RAM region (initial RAM and possible hotpluggable device memory). That way we do not need to do invasive changes in the EDK2 FW to support a dynamic RAM base. Still the user cannot request an initial RAM size greater than 255GB.

2019-03-05vl: Set machine ram_size, maxram_size and ram_slots earlierEric Auger
The machine RAM attributes will need to be analyzed during the configure_accelerator() process. especially kvm_type() arm64 machine callback will use them to know how many IPA/GPA bits are needed to model the whole RAM range. So let's assign those machine state fields before calling configure_accelerator.

2019-03-05hw/arm/virt: Split the memory map descriptionEric Auger
In the prospect to introduce an extended memory map supporting more RAM, let's split the memory map array into two parts: - the former a15memmap, renamed base_memmap, contains regions below and including the RAM. MemMapEntries initialized in this array have a static size and base address. - extended_memmap, only initialized with entries located after the RAM. MemMapEntries initialized in this array only get their size initialized. Their base address is dynamically computed depending on the the top of the RAM, with same alignment as their size. Eventually base_memmap entries are copied into the extended_memmap array. Using two separate arrays however clarifies which entries are statically allocated and those which are dynamically allocated. This new split will allow to grow the RAM size without changing the description of the high IO entries. We introduce a new virt_set_memmap() helper function which "freezes" the memory map. We call it in machvirt_init as memory attributes of the machine are not yet set when virt_instance_init() gets called. The memory map is unchanged (the top of the initial RAM still is 256GiB). Then come the high IO regions with same layout as before.

2019-03-04ui/cocoa: Perform UI operations only on the main threadPeter Maydell
The OSX Mojave release is more picky about enforcing the Cocoa API restriction that only the main thread may perform UI calls. To accommodate this we need to restructure the Cocoa code: * the special OSX main() creates a second thread and uses that to call the vl.c qemu_main(); the original main thread goes into the OSX event loop * the refresh, switch and update callbacks asynchronously tell the main thread to do the necessary work * the refresh callback no longer does the "get events from the UI event queue and handle them" loop, since we now use the stock OSX event loop. Instead our NSApplication sendEvent method will either deal with them or pass them on to OSX All these things have to be changed in one commit, to avoid breaking bisection. Note that since we use dispatch_get_main_queue(), this bumps our minimum version requirement to OSX 10.10 Yosemite (released in 2014, unsupported by Apple since 2017).

Currently the switchSurface method takes a DisplaySurface. We want to change our DisplayChangeListener's dpy_gfx_switch callback to do this work asynchronously on a different thread. The caller of the switch callback will free the old DisplaySurface immediately the callback returns, so to ensure that the other thread doesn't access freed data we need to switch to using the underlying pixman image instead. The pixman image is reference counted, so we will be able to take a reference to it to avoid it vanishing too early.

2019-03-04ui/cocoa: Ensure we have the iothread lock when calling into QEMUPeter Maydell
The Cocoa UI should run on the main thread; this is enforced in OSX Mojave. In order to be able to run on the main thread, we need to make sure we hold the iothread lock whenever we call into various QEMU UI midlayer functions.

2019-03-04s390x: Add floating-point extension facility to "qemu" cpu modelDavid Hildenbrand
The floating-point extension facility implemented certain changes to BFP, HFP and DFP instructions. As we don't implement HFP/DFP, we can ignore those completely. Related to BFP, the changes include - SET BFP ROUNDING MODE (SRNMB) instruction - BFP-rounding-mode field in the FPC register is changed to 3 bits - CONVERT FROM LOGICAL instructions - CONVERT TO LOGICAL instructions - Changes (rounding mode + XxC) added to -- CONVERT TO FIXED -- CONVERT FROM FIXED -- LOAD FP INTEGER -- LOAD ROUNDED -- DIVIDE TO INTEGER For TCG, we don't implement DIVIDE TO INTEGER, and it is harder to implement, so skip that. Also, as we don't implement PFPO, we can skip changes to that as well. The other parts are now implemented, we can indicate the facility. z14 PoP mentions that "The floating-point extension facility is installed in the z/Architecture architectural mode. When bit 37 is one, bit 42 is also one.", meaning that the DFP (decimal-floating-point) facility also has to be indicated. We can ignore that for now.

2019-03-04s390x/tcg: Handle all rounding modes overwritten by BFP instructionsDavid Hildenbrand
"round to nearest with ties away from 0" maps to float_round_ties_away. "round to prepare for shorter precision" maps to float_round_to_odd. As all instructions properly check for valid rounding modes in translate.c we can add an assert. Fix one missing empty line.

2019-03-04s390x/tcg: Implement rounding mode and XxC for LOAD ROUNDEDDavid Hildenbrand
With the floating-point extension facility, LOAD ROUNDED has a rounding mode specification and the inexact-exception control (XxC). Handle them just like e.g. LOAD FP INTEGER.

2019-03-04s390x/tcg: Implement XxC and checks for most FP instructionsDavid Hildenbrand
With the floating-point extension facility - CONVERT FROM LOGICAL - CONVERT TO LOGICAL - CONVERT TO FIXED - CONVERT FROM FIXED - LOAD FP INTEGER have both, a rounding mode specification and the inexact-exception control (XxC). Other instructions will be handled separatly. Check for valid rounding modes and forward also the XxC (via m4). To avoid a lot of boilerplate code and changes to the helpers, combine both, the m3 and m4 field in a combined 32 bit TCG variable. Perform checks at a central place, taking in account if the m3 or m4 field was ignore before the floating-point extension facility was introduced.

2019-03-04s390x/tcg: Prepare for IEEE-inexact-exception control (XxC)David Hildenbrand
Some instructions allow to suppress IEEE inexact exceptions. z14 PoP, 9-23, "Suppression of Certain IEEE Exceptions" IEEE-inexact-exception control (XxC): Bit 1 of the M4 field is the XxC bit. If XxC is zero, recogni- tion of IEEE-inexact exception is not suppressed; if XxC is one, recognition of IEEE-inexact excep- tion is suppressed. Especially, handling for overflow/unerflow remains as is, inexact is reported along z14 PoP, 9-23, "Suppression of Certain IEEE Exceptions" For example, the IEEE-inexact-exception control (XxC) has no effect on the DXC; that is, the DXC for IEEE- overflow or IEEE-underflow exceptions along with the detail for exact, inexact and truncated, or inexact and incremented, is reported according to the actual con- dition. Follow up patches will wire it correctly up for the applicable instructions.
