target/s390x: Fix some helper_ex problems (1) The OR of the low bits or R1 into INSN were not being done consistently; it was forgotten along all but the SVC path. (2) The setting of ILEN was wrong on SVC path for EXRL. (3) The data load for ICM read too much. Fix these by consolidating data load at the beginning, using get_ilen to control the number of bytes loaded, and ORing in the byte from R1. Use extract64 from the full aligned insn to extract arguments. Pass in ILEN rather than RET as the more natural way to give the required data along the SVC path.

softfloat: Implement run-time-configurable meaning of signaling NaN bit This patch modifies SoftFloat library so that it can be configured in run-time in relation to the meaning of signaling NaN bit, while, at the same time, strictly preserving its behavior on all existing platforms. Background: In floating-point calculations, there is a need for denoting undefined or unrepresentable values. This is achieved by defining certain floating-point numerical values to be NaNs (which stands for "not a number"). For additional reasons, virtually all modern floating-point unit implementations use two kinds of NaNs: quiet and signaling. The binary representations of these two kinds of NaNs, as a rule, differ only in one bit (that bit is, traditionally, the first bit of mantissa). Up to 2008, standards for floating-point did not specify all details about binary representation of NaNs. More specifically, the meaning of the bit that is used for distinguishing between signaling and quiet NaNs was not strictly prescribed. (IEEE 754-2008 was the first floating-point standard that defined that meaning clearly, see [1], p. 35) As a result, different platforms took different approaches, and that presented considerable challenge for multi-platform emulators like QEMU. Mips platform represents the most complex case among QEMU-supported platforms regarding signaling NaN bit. Up to the Release 6 of Mips architecture, "1" in signaling NaN bit denoted signaling NaN, which is opposite to IEEE 754-2008 standard. From Release 6 on, Mips architecture adopted IEEE standard prescription, and "0" denotes signaling NaN. On top of that, Mips architecture for SIMD (also known as MSA, or vector instructions) also specifies signaling bit in accordance to IEEE standard. MSA unit can be implemented with both pre-Release 6 and Release 6 main processor units. QEMU uses SoftFloat library to implement various floating-point-related instructions on all platforms. The current QEMU implementation allows for defining meaning of signaling NaN bit during build time, and is implemented via preprocessor macro called SNAN_BIT_IS_ONE. On the other hand, the change in this patch enables SoftFloat library to be configured in run-time. This configuration is meant to occur during CPU initialization, at the moment when it is definitely known what desired behavior for particular CPU (or any additional FPUs) is. The change is implemented so that it is consistent with existing implementation of similar cases. This means that structure float_status is used for passing the information about desired signaling NaN bit on each invocation of SoftFloat functions. The additional field in float_status is called snan_bit_is_one, which supersedes macro SNAN_BIT_IS_ONE. IMPORTANT: This change is not meant to create any change in emulator behavior or functionality on any platform. It just provides the means for SoftFloat library to be used in a more flexible way - in other words, it will just prepare SoftFloat library for usage related to Mips platform and its specifics regarding signaling bit meaning, which is done in some of subsequent patches from this series. Further break down of changes: 1) Added field snan_bit_is_one to the structure float_status, and correspondent setter function set_snan_bit_is_one(). 2) Constants <float16|float32|float64|floatx80|float128>_default_nan (used both internally and externally) converted to functions <float16|float32|float64|floatx80|float128>_default_nan(float_status*). This is necessary since they are dependent on signaling bit meaning. At the same time, for the sake of code cleanup and simplicity, constants <floatx80|float128>_default_nan_<low|high> (used only internally within SoftFloat library) are removed, as not needed. 3) Added a float_status* argument to SoftFloat library functions XXX_is_quiet_nan(XXX a_), XXX_is_signaling_nan(XXX a_), XXX_maybe_silence_nan(XXX a_). This argument must be present in order to enable correct invocation of new version of functions XXX_default_nan(). (XXX is <float16|float32|float64|floatx80|float128> here) 4) Updated code for all platforms to reflect changes in SoftFloat library. This change is twofolds: it includes modifications of SoftFloat library functions invocations, and an addition of invocation of function set_snan_bit_is_one() during CPU initialization, with arguments that are appropriate for each particular platform. It was established that all platforms zero their main CPU data structures, so snan_bit_is_one(0) in appropriate places is not added, as it is not needed.

We are missing (as for most other part) low address protection checks, PSW key / storage key checks and support for AR-mode. We fake an ADDRESSING exception when called from problem state (which seems to rely on PSW key checks to be in place) and if AR-mode is used. user mode will always see a PRIVILEDGED exception.

s390x/tcg: add basic MSA features The STFLE bits for the MSA (extension) facilities simply indicate that the respective instructions can be executed. The QUERY subfunction can then be used to identify which features exactly are available. Availability of subfunctions can also vary on real hardware. For now, we simply implement a CPU model without any available subfunctions except QUERY (which is always around). As all MSA functions behave quite similarly, we can use one translation handler for now. Prepare the code for implementation of actual subfunctions. At least MSA is helpful for now, as older Linux kernels require this facility when compiled for a z9 model. Allow to enable the facilities for the qemu cpu model.

So all PGM_ADDRESSING exceptions have to be forwarded to the guest. Since the initial definition of TEST PROTECTION, we now read globals (e.g. PSW mask), so we have to correctly mark the instruction (otherwise, e.g. booting fedora 27 fails). Also, the architecture explicitly specifies which exceptions are forwarded to the guest, this makes the code a little nicer.

target-s390x: basic PER event handling This patch add basic support to generate PER exceptions. It adds two fields to the cpu structure to record for the PER address and PER code & ATMID values. When an exception is triggered and a PER event is pending, the two PER values are copied to the lowcore area. At the end of an instruction, an helper is checking for a possible pending PER event and triggers an exception in that case. For that to work with branches, we need to disable TB chaining when PER is activated. Fortunately it's already in the TB flags. Finally in case of a SERVICE CALL exception, we need to trigger the PER exception immediately after. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Alexander Graf <agraf@suse.de>

target-s390x: PER successful-branching event support For the PER successful-branching event support, we can't rely on any QEMU infrastucture. We therefore call an helper in all places where a branch can be taken. We have to pay attention to the branch to next case, as it's still a taken branch. We don't need to care about the cases using goto_tb, as we have disabled them in the previous patch. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Alexander Graf <agraf@suse.de>

target-s390x: PER instruction-fetch event support For the PER instruction-fetch, we can't use the QEMU breakpoint infrastructure as it triggers for a single address and not a full address range, and as it actually stop before the instruction and not before. We therefore call an helper with the just fetched instruction address, which check if the address is within the PER address range. If it is the case, an event is recorded and will be signaled through an exception. Note that we implement here the PER-3 behaviour, that is an invalid opcode is not considered as an instruction fetch. Without PER-3 this behavious is undefined.

s390x/tcg: make STFL store into the lowcore Using virtual memory access is wrong and will soon include low-address protection checks, which is to be bypassed for STFL. STFL is a privileged instruction and using LowCore requires !CONFIG_USER_ONLY, so add the ifdef and move the declaration to the right place. This was originally part of a bigger STFL(E) refactoring.
