2020-09-07target/microblaze: Diagnose invalid insns in delay slotsRichard Henderson
These cases result in undefined and undocumented behaviour but the behaviour is deterministic, i.e cores will not lock-up or expose security issues. However, RTL will not raise exceptions either. Therefore, log a GUEST_ERROR and treat these cases as nops, to avoid corner cases which could put qemu into an invalid state. Tested-by: Edgar E.

2020-09-07target/microblaze: Collected fixes for env->iflagsRichard Henderson
There are several problems here that can result in soft lockup, depending on exactly where an interrupt or exception is delivered: Include BIMM_FLAG in IFLAGS_TB_MASK, since it needs to follow D_FLAG. Ensure that iflags is 0 when entering an interrupt/exception handler. Add mb_cpu_synchronize_from_tb to restore iflags from tb->flags. The change to t_sync_flags is cosmetic, but makes the code clearer. This fixes the reported regression in acceptance/replay_kernel.py.

2020-09-07gitlab: expand test coverage for crypto buildsDaniel P. Berrangé
Most jobs test the latest nettle library. This adds explicit coverage for latest gcrypt using Fedora, and old gcrypt and nettle using CentOS-7. The latter does a minimal tools-only build, as we only need to validate that the crypto code builds and unit tests pass. Finally a job disabling both nettle and gcrypt is provided to validate that gnutls still works. Signed-off-by: Daniel P.

2020-09-07crypto: fix build with gcrypt enabledDaniel P. Berrangé
If nettle is disabled and gcrypt enabled, the compiler and linker flags needed for gcrypt are not passed. Gnutls was also not added as a dependancy when gcrypt is enabled. Attempting to add the library dependencies at the same time as the source dependencies is error prone, as there are alot of different rules for picking which sources to use, and some of the source files use code level conditionals intead. It is thus clearer to add the library dependencies separately. Signed-off-by: Daniel P.

Now that we can use all our QEMU test containers in the gitlab-CI, we can easily add some jobs that test cross-compilation for various architectures. There is just only small ugliness: Since the shared runners on gitlab.com are single-threaded, we have to split each compilation job into two parts (--disable-user and --disable-system), and exclude some additional targets, to avoid that the jobs are running too long and hitting the timeout of 1 h.

2020-09-04ui/gtk: Update refresh interval after widget is realizedPhilippe Mathieu-Daudé
Nikola reported on Windows when gd_vc_gfx_init() is called, the window is not yet realized, so we run gd_refresh_rate_millihz(NULL) which returns 0 milli-Hertz. When a Widget is realized, it fires a 'realized' event. We already have the gd_draw_event() handler registered for this even, so simply move the gd_refresh_rate_millihz() there. When the event fires, the window is known to exist. This completes commit c4c00922cc original intention.

2020-09-04ui: Add more mouse buttons to SPICEFrediano Ziglio
Add support for SIDE and EXTRA buttons. The constants for buttons in both SPICE and QEMU are defined as LEFT MIDDLE RIGHT UP DOWN SIDE EXTRA (same order). "button_mask" contains for each bit the state of a button. Qemu currently uses bits 0, 1, 2 respectively as LEFT, RIGHT, MIDDLE; also add bits 4 and 5 as UP and DOWN (using wheel movements). SPICE protocol uses a bitmask based on the order above where LEFT is bit 0, MIDDLE is bit 1 and so on till EXTRA being bit 6. To avoid clash with Qemu usage SPICE bitmask from SIDE are move a bit more resulting respectively in 0x40 and 0x80 values.

2020-09-03tcg: Fix tcg gen for vectorized absolute valueStephen Long
The fallback inline expansion for vectorized absolute value, when the host doesn't support such an insn was flawed. E.g. when a vector of bytes has all elements negative, mask will be 0xffff_ffff_ffff_ffff. Subtracting mask only adds 1 to the low element instead of all elements becase -mask is 1 and not 0x0101_0101_0101_0101.
