* cpus: pass CPUState to run_on_cpu helpersAlex Bennée2016-09-271-21/+10Star
| | | | | | | | | | | | | | | | | | | | | | | | | | CPUState is a fairly common pointer to pass to these helpers. This means if you need other arguments for the async_run_on_cpu case you end up having to do a g_malloc to stuff additional data into the routine. For the current users this isn't a massive deal but for MTTCG this gets cumbersome when the only other parameter is often an address. This adds the typedef run_on_cpu_func for helper functions which has an explicit CPUState * passed as the first parameter. All the users of run_on_cpu and async_run_on_cpu have had their helpers updated to use CPUState where available.

* target-ppc: Eliminate redundant and incorrect function booke206_page_size_to_tlbAaron Larson2016-07-011-6/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eliminate redundant and incorrect booke206_page_size_to_tlb function from ppce500_spin.c in preference to previously existing but newly exported definition from e500.c Defect analysis: The booke206_page_size_to_tlb function in e500.c was updated in commit 2bd9543 "ppc: booke206: use MAV=2.0 TSIZE definition, fix 4G pages" to reflect a change in the definition of MAS1_TSIZE_SHIFT from 8 (corresponding to a min TLB page size of 4kb) to a value of 7 (TLB page size 2k). The booke206_page_size_to_tlb() function defined in ppce500_spin.c was never updated to reflect the change in MAS1_TSIZE_SHIFT. In http://lists.nongnu.org/archive/html/qemu-ppc/2016-06/msg00533.html, Scott Wood suggested this "root cause" explanation: SW> The patch that changed MAS1_TSIZE_SHIFT from 8 to 7 was around the SW> same time as the patch that added this code, which is probably why SW> adjusting it got missed. Commit 2bd9543cd3 did update the SW> equivalent code in ppce500_mpc8544ds.c, which now resides in SW> hw/ppc/e500.c and has been changed to not assume a power-of-2 SW> size. The ppce500_spin version should be eliminated. Signed-off-by: Aaron Larson <alarson@ddci.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

* Convert (ffs(val) - 1) to ctz32(val)Stefan Hajnoczi2015-04-281-1/+1
| | | | | | | | | | | | | | | | | | | This commit was generated mechanically by coccinelle from the following semantic patch: @@ expression val; @@ - (ffs(val) - 1) + ctz32(val) The call sites have been audited to ensure the ffs(0) - 1 == -1 case never occurs (due to input validation, asserts, etc). Therefore we don't need to worry about the fact that ctz32(0) == 32.
