render-cg: allocate VRAM in the heap; default to double buffering * Create a heap arena over the OS stack, large enough to hold two VRAMs as was previously done, unless GINT_NO_OS_STACK is set at compile time. (This replaces GINT_USER_VRAM.) * Allocate a single VRAM in the heap at startup. * Use double buffering by default as triple buffering is almost entirely useless. dudpate() waits if both VRAMs are identical to prevent corruption, but this can be bypassed with R61524 functions as usual. This adds about 180 kB of heap data to any add-in using default settings.

kmalloc: implement a custom segregated list allocator The new allocator uses a segregated best-fit algorithm with exact-size lists for all sizes between 8 bytes (the minimum) and 60 bytes, one list for blocks of size 64-252 and one for larger blocks. Arenas managed by this allocator have built-in statistics that track used and free memory (accounting for block headers), peak memory, and various allocation results. In addition, the allocator has self-checks in the form of integrity verifications, that can be enabled with -DGINT_KMALLOC_DEBUG=1 at configuration time or with the :dev configuration for GiteaPC. This is used by gintctl. The kmalloc interface is extended with a new arena covering all unused memory in user RAM, managed by gint's allocator. It spans about 4 kB on SH3 fx-9860G, 16 kB on SH4 fx-9860G, and 500 kB on fx-CG 50, in addition to the OS heap. This new arena is now the default arena for malloc(), except on SH3 where some heap problems are currently known.

# CPU driver
kernel: driver and world system overhaul Changes in the driver and world system: * Rewrite driver logic to include more advanced concepts. The notion of binding a driver to a device is introduced to formalize wait(); power management is now built-in instead of being handled by the drivers (for instance DMA). The new driver model is described in great detail in <gint/drivers.h> * Formalized the concept of "world switch" where the hardware state is saved and later restored. As a tool, the world switch turns out to be very stable, and allows a lot of hardware manipulation that would be edgy at best when running in the OS world. * Added a GINT_DRV_SHARED flag for drivers to specify that their state is shared between worlds and not saved/restored. This has a couple of uses. * Exposed a lot more of the internal driver/world system as their is no particular downside to it. This includes stuff in <gint/drivers.h> and the driver's state structures in <gint/drivers/states.h>. This is useful for debugging and for cracked concepts, but there is no API stability guarantee. * Added a more flexible driver level system that allows any 2-digit level to be used. Feature changes: * Added a CPU driver that provides the VBR change as its state save. Because the whole context switch relied on interrupts being disabled anyway, there is no longer an inversion of control when setting the VBR; this is just part of the CPU driver's configuration. The CPU driver may also support other features such as XYRAM block transfer in the future. * Moved gint_inthandler() to the INTC driver under the name intc_handler(), pairing up again with intc_priority(). * Added a reentrant atomic lock based on the test-and-set primitive. Interrupts are disabled with IMASK=15 for the duration of atomic operations. * Enabled the DMA driver on SH7305-based fx-9860G. The DMA provides little benefit on this platform because the RAM is generally faster and buffers are ultimately small. The DMA is still not available on SH3-based fx-9860G models. * Solved an extremely obnoxious bug in timer_spin_wait() where the timer is not freed, causing the callback to be called when interrupts are re-enabled. This increments a random value on the stack. As a consequence of the change, removed the long delays in the USB driver since they are not actually needed. Minor changes: * Deprecated some of the elements in <gint/hardware.h>. There really is no good way to "enumerate" devices yet. * Deprecated gint_switch() in favor of a new function gint_world_switch() which uses the GINT_CALL abstraction. * Made the fx-9860G VRAM 32-aligned so that it can be used for tests with the DMA. Some features of the driver and world systems have not been implemented yet, but may be in the future: * Some driver flags should be per-world in order to create multiple gint worlds. This would be useful in Yatis' hypervisor. * A GINT_DRV_LAZY flag would be useful for drivers that don't want to be started up automatically during a world switch. This is relevant for drivers that have a slow start/stop sequence. However, this is tricky to do correctly as it requires dynamic start/stop and also tracking which world the current hardware state belongs to.

cpu: allow functions to block the sleep() function This change introduces new sleep_block() and sleep_unblock() functions that control whether the sleep() function actually sleeps. This type of behavior was already implemented in the DMA driver, since DMA access to on-chip memory is paused when sleeping (on-chip memory being paused itself), which would make waiting for a DMA transfer a freeze. Because DMA transfers are now asynchronous, and USB transfers that may involve on-chip memory are coming, this API change allows the DMA and USB drivers to block the sleep() function so that user code can sleep() for interrupts without having to worry about asynchronous tasks requiring on-chip memory to complete.

There really is no good way to "enumerate" devices yet. * Deprecated gint_switch() in favor of a new function gint_world_switch() which uses the GINT_CALL abstraction. * Made the fx-9860G VRAM 32-aligned so that it can be used for tests with the DMA. Some features of the driver and world systems have not been implemented yet, but may be in the future: * Some driver flags should be per-world in order to create multiple gint worlds. This would be useful in Yatis' hypervisor. * A GINT_DRV_LAZY flag would be useful for drivers that don't want to be started up automatically during a world switch. This is relevant for drivers that have a slow start/stop sequence. However, this is tricky to do correctly as it requires dynamic start/stop and also tracking which world the current hardware state belongs to.

keydev: add a keyboard device layer to abstract away globals The new keyboard device (keydev) interface implements the kernel's view of a keyboard providing input events. Its main role is to abstract all the globals of the KEYSC driver and getkey functions into a separate object: the "keyboard device". The device implements event transformations such as modifiers and repeats, instead of leaving them to getkey. While this can seem surprising at first, a real keyboard controller is responsible for repeats and modifier actions depend on the state of the keyboard which is only tracked in real-time. In this commit, getkey() has not changed yet apart from indirectly using the keydev interface with pollevent(). It will be changed soon to use event transforms in keydev_read(), and will be left in charge of providing repeat profiles, handling return-to-menu, backlight changes and timeouts, all of which are user convenience features.

# Memory allocator
kmalloc: implement a custom segregated list allocator The new allocator uses a segregated best-fit algorithm with exact-size lists for all sizes between 8 bytes (the minimum) and 60 bytes, one list for blocks of size 64-252 and one for larger blocks. Arenas managed by this allocator have built-in statistics that track used and free memory (accounting for block headers), peak memory, and various allocation results. In addition, the allocator has self-checks in the form of integrity verifications, that can be enabled with -DGINT_KMALLOC_DEBUG=1 at configuration time or with the :dev configuration for GiteaPC. This is used by gintctl. The kmalloc interface is extended with a new arena covering all unused memory in user RAM, managed by gint's allocator. It spans about 4 kB on SH3 fx-9860G, 16 kB on SH4 fx-9860G, and 500 kB on fx-CG 50, in addition to the OS heap. This new arena is now the default arena for malloc(), except on SH3 where some heap problems are currently known.

src/kmalloc/arena_gint.c
kmalloc: create the kmalloc interface This change introduces a centralized memory allocator in the kernel. This interface can call into multiple arenas, including the default OS heap and planned arenas managed by a gint algorithm. The main advantage of this method is that it allows the heap to be extended over previously-unused areas of RAM such as the end of the static RAM region (apart from where the stack resides). Not using the OS heap is also sometimes a matter of correctness since on some OS versions the heap is known to fragment badly and degrade over time. I hope the deep control this interfaces gives over meomry allocation will allow very particular applications like object-specific allocators in fragmented SPU memory. This change does not introduce any new algorithm or arena so programs should behave exactly as before.

Revert "meta: build with -ffreestanding" This reverts commit b0c4e6fd2fe46211002bfd0efa26612f79285f39. After investigation, this is related to builtin functions. Using -fno-builtin is a less invasive way to solve the problem. However this appears to be a bug [1]; in theory fat LTO objects should solve that. I will handle this matter at the fxSDK level by adding -fno-builtin right and experimenting with the bugfix in binutils 2.43. [1] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114337
