target/s390x: start moving TCG-only code to tcg/

2021-07-07T12:01:56+00:00

move everything related to translate, as well as HELPER code in tcg/ mmu_helper.c stays put for now, as it contains both TCG and KVM code. After the reshuffling, update MAINTAINERS accordingly.

target/s390x: rename internal.h to s390x-internal.h

2021-07-07T12:01:56+00:00

The internal.h file is renamed to s390x-internal.h, because of the risk of collision with other files with the same name.

Rename to s390_cpu_set_psw and s390_cpu_get_psw_mask at the same time. Adjust so that they compile for user-only.

target/s390x: Implement the MVPG condition-code-option bit

2021-03-15T10:03:20+00:00

If the CCO bit is set, MVPG should not generate an exception but report page translation faults via a CC code. Create a new helper, access_prepare_nf, which can use probe_access_flags in non-faulting mode, and then handle watchpoints.

s390x/tcg: Implement MONITOR CALL

2020-10-02T11:52:49+00:00

Recent upstream Linux uses the MONITOR CALL instruction for things like BUG_ON() and WARN_ON(). We currently inject an operation exception when we hit a MONITOR CALL instruction - which is wrong, as the instruction is not glued to specific CPU features. Doing a simple WARN_ON_ONCE() currently results in a panic: [ 18.162801] illegal operation: 0001 ilc:2 [#1] SMP [ 18.162889] Modules linked in: [...] [ 18.165476] Kernel panic - not syncing: Fatal exception: panic_on_oops With a proper implementation, we now get: [ 18.242754] ------------[ cut here ]------------ [ 18.242855] WARNING: CPU: 7 PID: 1 at init/main.c:1534 [...] [ 18.242919] Modules linked in: [...] [ 18.246262] ---[ end trace a420477d71dc97b4 ]--- [ 18.259014] Freeing unused kernel memory: 4220K Reported-by: Christian Borntraeger Signed-off-by: David Hildenbrand Reviewed-by: Richard Henderson Message-Id: <20200918085122.26132-1-david@redhat.com> Signed-off-by: Cornelia Huck

target/s390x: Remove duplicated ifdef macro

2020-01-27T11:13:09+00:00

Commit ae71ed8610 replaced the use of global max_cpus variable with a machine property, but introduced a unnecessary ifdef, as this block is already in the 'not CONFIG_USER_ONLY' branch part: 86 #if defined(CONFIG_USER_ONLY) 87 ... 106 #else /* !CONFIG_USER_ONLY */ 107 ... 292 static void do_ext_interrupt(CPUS390XState *env) 293 { ... 313 #ifndef CONFIG_USER_ONLY 314 MachineState *ms = MACHINE(qdev_get_machine()); 315 unsigned int max_cpus = ms->smp.max_cpus; 316 #endif To ease code review, remove the duplicated preprocessor macro, and move the declarations at the beginning of the statement.
