The Neon half-precision conversion operations (VCVT.F16.F32 and VCVT.F32.F16) use ARM standard floating-point arithmetic, unlike the VFP versions (VCVTB and VCVTT). Signed-off-by:

Correctly handle NaNs in float16_to_float32(), by defining and using a float16ToCommonNaN() function, as we do with the other formats. Signed-off-by:

Peter Maydell authored
Fix various bugs in the single-to-half-precision conversion code: * input NaNs not correctly converted in IEEE mode (fixed by defining and using a commonNaNToFloat16()) * wrong values returned when converting NaN/Inf into non-IEEE half precision value * wrong values returned for conversion of values which are on the boundary between denormal and zero for the half precision format * zeroes not correctly identified * excessively large results in non-IEEE mode should generate InvalidOp, not Overflow Signed-off-by:

Honour the default_nan_mode flag when doing conversions between different floating point formats, as well as when returning a NaN from a two-operand floating point function. This corrects the behaviour of float<->double conversions on both ARM and SH4. Signed-off-by:

Add a float16 type to softfloat, rather than using bits16 directly. Also add the missing functions float16_is_quiet_nan(), float16_is_signaling_nan() and float16_maybe_silence_nan(), which are needed for the float16 conversion routines. Signed-off-by:

The returned value when doing saturating signed 64->32 bit conversion of a negative number was incorrect due to a missing cast. Signed-off-by:

VQMOVUN does a signed-to-unsigned saturating conversion. This is different from both the signed-to-signed and unsigned-to-unsigned conversions already implemented, so we need a new set of helper functions (neon_unarrow_sat*). Signed-off-by:

In case a chrooted build uses XEN or KVM, a looped mount needs to be done to setup the chroot. The ioctl for loop mount works correctly for arm, mips, ppc32 and sh4, so its now activated. Signed-off-by:Riku Voipio <riku.voipio@nokia.com>

The current print_mmap func is only enabled when the target supports the mmap syscall, but both mmap and mmap2 syscalls use it. This leads to a build failure when the target supports mmap2 but not mmap. Signed-off-by:

The current init_paths code will attempt to opendir() every single file it finds. This can obviously generated a huge number of syscalls with even a moderately small sysroot that will fail. Since the readdir() call provides the file type in the struct itself, use it. On my system, this prevents over 1000 syscalls from being made at every invocation of a target binary, and I only have a C library installed. Signed-off-by:

This brings flatload.c more in line with the current Linux FLAT loader which allows targets to handle various FLAT aspects in their own way. For the common behavior, the new functions get stubbed out. Signed-off-by:

The current auto-stack sizing works like it does on a NOMMU system; the problem is that this only works if the envp/argv arrays are fairly slim. On a desktop system, this is rarely the case, and can easily blow past the stack and into data/text regions as the default stack for FLAT progs is a mere 4KiB. So rather than rely on the NOMMU calculation (which is only there because NOMMU can't easily allocate gobs of contiguous mem), calc the full space actually needed and let the MMU host make space.

Different AHCI controllers have a different number of ports, so the core shouldn't care about the amount of ports available. This patch makes the number of ports available to the AHCI core runtime configurable, allowing us to have multiple different AHCI implementations with different amounts of ports. Signed-off-by:

The ahci code was missing its soft reset functionality. This wasn't really an issue for Linux guests, but Windows gets confused when the controller doesn't reset when it tells it so. Using this patch I can now successfully boot Windows 7 from AHCI using AHCI enabled SeaBIOS. Signed-off-by:

The drive sends a d2h init fis on initialization. Usually, the guest doesn't receive fises yet at that point though, so the delivery is deferred. Let's reflect that by sending the init fis on fis receive enablement. Signed-off-by:

Sebastian's patch already did a pretty good job at splitting up ICH-9 AHCI code and the AHCI core. We need some more though. Copyright was missing, the lspci dump belongs to ICH-9, we don't need the AHCI core to have its own qdev device duplicate. So let's split them a bit more in this patch, making things easier to read an understand. Signed-off-by:
