Kernel/Threads: Dynamically allocate the TLS region for threads.
2016-05-12 21:51:35 -04:00
Subv d192fb066d Kernel/Threads: Dynamically allocate the TLS region for threads in the BASE region of the linear heap.
Each thread gets a 0x200-byte area from the 0x1000-sized page, when all 8 thread slots in a single page are used up, the kernel allocates a new page to hold another 8 entries.

This is consistent with what the real kernel does.

Lioncash 6b7ebb3f82 hle: Get rid of global access to g_reschedule
This shouldn't be directly exposed if there's already a partial API that operates on it.
We can just provide the rest of that API.

Yuri Kunde Schlesner dc39d06950 Ensure all kernel objects are released during shutdown
This commit fixes several kernel object leaks. The most severe of them
was threads not being removed from the private handle table used for
CoreTiming events. This resulted in Threads never being released, which
in turn held references to Process, causing CodeSets to never be freed
when loading other applications.

Yuri Kunde Schlesner 7ada357b2d Memmap: Re-organize memory function in two files
memory.cpp/h contains definitions related to acessing memory and
configuring the address space
mem_map.cpp/h contains higher-level definitions related to configuring
the address space accoording to the kernel and allocating memory.

The TLS area for thread T with id Ti is located at TLS_AREA_VADDR + (Ti - 1) * 0x200.
This allows some games like Mario Kart 7 to continue further.

archshift 4fb75d220a Misc cleanup of common and related functions 2015-02-19 22:26:25 -08:00
archshift ef24e72b26 Asserts: break/crash program, fit to style guide; log.h->assert.h
Involves making asserts use printf instead of the log functions (log functions are asynchronous and, as such, the log won't be printed in time)
As such, the log type argument was removed (printf obviously can't use it, and it's made obsolete by the file and line printing)

Also removed some GEKKO cruft.

Kevin Hartman 5fcbfc06eb Scheduler refactor Pt. 1
* Simplifies scheduling logic, specifically regarding thread status. It should be much clearer which statuses are valid
for a thread at any given point in the system.
* Removes dead code from thread.cpp.
* Moves the implementation of resetting a ThreadContext to the corresponding core's implementation.

Other changes:
* Fixed comments in arm interfaces.
* Updated comments in thread.cpp
* Removed confusing, useless, functions like MakeReady() and ChangeStatus() from thread.cpp.
* Removed stack_size from Thread. In the CTR kernel, the thread's stack would be allocated before thread creation.

Yuri Kunde Schlesner 88a4a808c6 Kernel: Stop creating useless Handles during object creation
They're finally unnecessary, and will stop cluttering the application's
handle table.

Yuri Kunde Schlesner 52f58e64ef Kernel: Make WaitObjects share ownership of Threads waiting on them
During normal operation, a thread waiting on an WaitObject and the
object hold mutual references to each other for the duration of the
wait.

If a process is forcefully terminated (The CTR kernel has a SVC to do
this, TerminateProcess, though no equivalent exists for threads.) its
threads would also be stopped and destroyed, leaving dangling pointers
in the WaitObjects.

The solution is to simply have the Thread remove itself from WaitObjects
when it is stopped. The vector of Threads in WaitObject has also been
changed to hold SharedPtrs, just in case. (Better to have a reference
cycle than a crash.)

Yuri Kunde Schlesner 7725256f64 Explicitly instantiate constructors/destructors for Kernel objects
This should speed up compile times a bit, as well as enable more liberal
use of forward declarations. (Due to SharedPtr not trying to emit the
destructor anymore.)
