Fifo overflow fix
The idea behind separating the CPU and GPU thread path is to prevent two threads executing the same function (SetCPStatusFromCPU) at the same time. The CPU thread gets to that function via GetherPipeBursted and the GPU thread gets there via SetCPStatusFromGPU. I wrote the original (factored) version as I like to keep code duplication to a minimum. This worked most of the time but not all of the time. It was a good move to separate it to a GPU version and a CPU version, but then the GPU version called the CPU version at the tail end. Removing the call (as in this PR) prevents the FIFO overflow in Starfox Adventures.
The "Updating the CPStatus before FIFO events" change is simply there to keep the DC code path and the SC code path consistent in the !GPLinked scenario. The SC code path does the same thing when !GPLinked via RunGPU. Putting the SetCPStatus call before the !GPLinked state changes the DC code path to do the same thing. The more we keep the DC and SC code paths consistent, the better.
Forcing the exception check on interrupts is the change for The Last Story. It makes the emulator process interrupts more responsively on CP interrupts.
The HiWatermark check is something that old (pre-2010) versions of Dolphin used to do. Games like Battalion Wars 2 do not expect the GPU to run so slowly and do not have the code to react to that situation, so this change makes the emulator extra careful in those situations.
* Added country flags for games from Netherlands and Spain
* Added separate category for Region Free games (Uses European flag as placeholder)
* Added missing country filter options in "show regions" menu
* Rearranged country filters for readability
* Incremented CACHE_REVISION
Also fixed various country filters not showing up as options in the "Show regions" menu.
There was a longstanding hack that defined ucontext_t manually to work
around the lack of this header on the Android NDK. However, it looks
like newer NDK versions now have it like good little POSIX boys, and my
recent header reshuffle broke the build on those versions, presumably
because the real and fake definitions of ucontext_t end up included in
the same file where they weren't under the old organization.
Rather than try to revert the conflict, this commit just removes the
hack. The buildbot's NDK will need to be upgraded.
This wasn't too much of a concern since we normally don't care about this feature set, but it is nice when testing on new devices and they don't
support the higher feature sets but want to run under software renderer.
The Mesa softpipe and PowerVR 5xx drivers don't support higher GL versions, but they shouldn't exit out just because they couldn't get a GL3 function
pointer that isn't even going to be used at that point.
The ActionBar method of doing the tabular layout is deprecated on Android 5.0.
This method alleviates those deprecations while providing the same functionality.
