2015-02-18s390x/mmu: Add function for accessing guest memoryThomas Huth
According to the POP specification, the parameter blocks of various functions like the IO instructions are accessed with logical addresses. Thus we need a function that can read or write a buffer from/to the guest's logical address space. This patch now provides a function that can be used to access virtual guest memory by using the mmu_translate function of QEMU to convert the virtual addresses to physical.

2015-02-18s390x/mmu: Renaming related to the ASCE confusionThomas Huth
An Address Space Control Element (ASCE) is only the very first unit of an s390 address translation (normally residing in one of the control registers). The entries in the page tables are called differently. So let's call the relevant variable pt_entry instead of asce in mmu_translate_pte() to avoid future confusion (thus there is no functional change in this patch, just renaming).

2015-02-18s390x/mmu: Skip exceptions properly when translating addresses for debugThomas Huth
When a fault occurs during the MMU lookup in s390_cpu_get_phys_page_debug(), the trigger_page_fault() function writes the translation exception code into the lowcore - something you would not expect during a memory access by the debugger. Ease this problem by adding an additional parameter to mmu_translate() which can be used to specify whether a program check and the translation exception code should be injected or not.

2015-02-18s390x/mmu: Fix the handling of the table levelsThomas Huth
The current code used a wrong and very confusing way of dealing with the table levels by introducing a "fake level above current". However, the real problem was simply that the checks for the region/segment invalid bit and for the matching region/segment level was done at the wrong spot in the code - it has to be done after the first table entry has been looked up instead (e.g. there is also no "invalid" bit in the ASCE itself and the current "level" has to be the same as the level in the entry that we just looked up). Also the entries for the segment table are quite a bit different compared to the region table entries. So this patch moves the related code into the function mmu_translate_segment() to make it clear at which table level we currently are and to get rid of the ugly switch-statement in the function mmu_translate_region().

2015-02-13s390x/ipl: drop reipl parameters on resetsFan Zhang
Whenever a reboot initiated by the guest is done, the reipl parameters should remain valid. The disk configured by the guest is to be used for ipl'ing. External reboot/reset request (e.g. via virsh reset guest) should completely reset the guest to the initial state, and therefore also reset the reipl parameters, resulting in an ipl behaviour of the initially configured guest. This could be an external kernel or a disk.

2015-02-03target-s390x: fix and optimize slb* and slbg* computation of carry/borrow flagTorbjorn Granlund
This patch fixes the bug with borrow_in being set incorrectly, but it also simplifies the logic to be much more plain, improving speed. It fixes both the 32-bit SLB* and 64-bit SLBG*. The SLBG* change has been well-tested. I haven't tested the SLB* change explicitly, but the code was copy-pasted from the tested code. The error of these functions' current implementations would not likely be triggered by compiler-generated code, since the only error was in the state of the carry/borrow flag. Compilers rarely generate an instruction sequence such as carry-set -> carry-set-and-use -> carry-use. (With Paolo's fix and mine, there are still a couple of failures from GMP's testsuite, but they are almost surely due to incorrect code generation from gcc 4.9. But since this gcc is running under qemu, it might be qemu bugs. I intend to investigate this.)

2014-12-16qemu-log: add log category for MMU infoAntony Pavlov
Running barebox on qemu-system-mips* with '-d unimp' overloads stderr by very very many mips_cpu_handle_mmu_fault() messages: mips_cpu_handle_mmu_fault address=b80003fd ret 0 physical 00000000180003fd prot 3 mips_cpu_handle_mmu_fault address=a0800884 ret 0 physical 0000000000800884 prot 3 mips_cpu_handle_mmu_fault pc a080cd80 ad b80003fd rw 0 mmu_idx 0 So it's very difficult to find LOG_UNIMP message. The mips_cpu_handle_mmu_fault() messages appear on enabling ANY logging! It's not very handy. Adding separate log category for *_cpu_handle_mmu_fault() logging fixes the problem.
