2010-03-18Replace assert(0) with abort() or cpu_abort()Blue Swirl3-5/+5
When building with -DNDEBUG, assert(0) will not stop execution so it must not be used for abnormal termination. Use cpu_abort() when in CPU context, abort() otherwise. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-03-17Large page TLB flushPaul Brook1-1/+2
QEMU uses a fixed page size for the CPU TLB. If the guest uses large pages then we effectively split these into multiple smaller pages, and populate the corresponding TLB entries on demand. When the guest invalidates the TLB by virtual address we must invalidate all entries covered by the large page. However the address used to invalidate the entry may not be present in the QEMU TLB, so we do not know which regions to clear. Implementing a full vaiable size TLB is hard and slow, so just keep a simple address/mask pair to record which addresses may have been mapped by large pages. If the guest invalidates this region then flush the whole TLB. Signed-off-by: Paul Brook <paul@codesourcery.com>

2010-02-09target-sh4: MMU: separate execute and read/write permissionsAurelien Jarno1-21/+6
On SH4, the ITLB and UTLB configurations are memory mapped, so loading ITLB entries from UTLB has to be simulated correctly. For that the QEMU TLB has to be handle the execute (ITLB) and read/write permissions (UTLB) seperately. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-02-09target-sh4: MMU: optimize UTLB accessesAurelien Jarno1-24/+14
With the current code, the QEMU TLB is setup to match the read/write mode of the MMU fault. This means when read access is done, the page is setup in read-only mode. When the page is later accessed in write mode, an MMU fault happened, and the page is switch in write-only mode. This flip-flop causes a lot of calls to the MMU code and slow down the emulation. This patch changes the MMU emulation, so that the QEMU TLB is setup to match the UTLB protection key. This impressively increase the speed of the emulation.

2010-02-09target-sh4: MMU: fix mem_idx computationAurelien Jarno1-1/+1
The mem_idx is wrongly computed. As written in target-sh4/cpu.h, mode 0 corresponds to kernel mode (SR_MD = 1), while mode 1 corresponds to user mode (SR_MD = 0). Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori2-4/+4
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl1-2/+2
Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-08-24cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signalNathan Froyd1-0/+1
handle_cpu_signal is very nearly copy-paste code for each target, with a few minor variations. This patch sets up appropriate defaults for a generic handle_cpu_signal and provides overrides for particular targets that did things differently. Fixing things like the persistent (XXX: use sigsetjmp) should now become somewhat easier. Previous comments on this patch suggest that the "activate soft MMU for this block" comments refer to defunct functionality. I have removed such blocks for the appropriate targets in this patch.
