Sebastian Valle 0315253319 GPU/MMEInterpreter: Ignore the 'exit' flag when it's executed inside a delay slot. 
It seems instructions marked with the 'exit' flag will not cause an exit when executed within a delay slot.

This was hwtested by fincs.

Sebastian Valle 8b4f7a9c5e Merge pull request #1956 from lioncash/process-thread 
kernel/process: Start the main thread using the specified ideal core
 2018-12-30 20:32:41 -05:00
Subv 7d6721e3ae Removed unused file. 
This is a leftover from #1792
 2018-12-03 23:52:38 -05:00
Subv a052151664 GPU: Don't try to route PFIFO methods (0-0x40) to the other engines. 2018-12-03 23:52:18 -05:00
Sebastian Valle a442958916 Merge pull request #1843 from lioncash/table 
hle/service: Update function tables for erpt:c and usb's IClientEpSession
 2018-12-03 12:21:28 -05:00
Subv b0ec648f85 Services/VI: Dereferencing an uninitialized std::optional is undefined behavior. 
Assert that it is not empty before using it in the DequeueBuffer wait callback.
 2018-11-30 16:06:49 -05:00
Subv 747e579d97 Logging: Change the TimeStretch::Process log from debug to trace level. 
This function is called too many times and makes the debug logging basically unusable due to the spam.
 2018-09-20 22:33:54 -05:00
Subv c865df9ca7 RasterizerGL: Use the correct framebuffer when clearing via the CLEAR_BUFFERS register. 
Previously we were clearing the default backbuffer framebuffer.

Found thanks to a Piglit test :)
 2018-09-20 22:31:53 -05:00
Subv 415fd53a49 Shaders: Implemented multiple-word loads and stores to and from attribute memory. 
This seems to be an optimization performed by nouveau.
 2018-09-15 11:21:21 -05:00
Subv 46b33657b6 GPU: Basic implementation of the Kepler Inline Memory engine (p2mf). 
This engine writes data from a FIFO register into the configured address.
 2018-09-12 13:57:08 -05:00
Subv 6e6071b6f9 GPU/DMA: Partially implemented the 'enable_2d' bit in the DMA engine. 
When not set, this tells the GPU to only use the X size when performing a DMA copy.
This is only implemented for linear->linear and tiled->tiled copies. Conversion copies still retain the assert.

This bit is unset by some games for various purposes, and by nouveau when copying the vertex buffers.
 2018-09-08 16:02:16 -05:00
Sebastian Valle b151ff8867 Merge pull request #1166 from lioncash/typo 
filesystem: Fix typo in log message
 2018-08-25 07:19:46 -05:00
Subv ca79c467bb Shaders: Implement depth writing in fragment shaders. 
We'll write <last color output reg + 2> to gl_FragDepth.
 2018-08-20 21:57:56 -05:00
Subv 7b21918d83 Shaders: Fixed the coords in TEX with Texture2D. 
The X and Y coordinates should be in gpr8 and gpr8+1, respectively.

This fixes the cutscene rendering in Sonic Mania.
 2018-08-20 20:45:46 -05:00
Subv c65f043274 Shaders: Log and crash when using an unimplemented texture type in a texture sampling instruction. 2018-08-20 20:44:56 -05:00
Subv 9e19247ca3 GPU: Implemented the logic op functionality of the GPU. 
This will ASSERT if blending is enabled at the same time as logic ops.
 2018-08-20 18:44:47 -05:00
Subv 181efe72a6 GLState: Allow enabling/disabling GL_COLOR_LOGIC_OP independently from blending. 2018-08-20 18:43:11 -05:00
Subv b55ca15b4b GPU: Added registers for the logicop functionality. 2018-08-20 18:42:36 -05:00
Subv 1318ecc2f1 Shaders: Write all the enabled color outputs when a fragment shader exits. 
We were only writing to the first render target before.
Note that this is only the GLSL side of the implementation, supporting multiple render targets requires more changes in the OpenGL renderer.

Dual Source blending is not implemented and stuff that uses it might not work at all.
 2018-08-20 17:31:25 -05:00
Subv cab352e38c Rasterizer: Reinterpret the raw texture bytes instead of blitting (and thus doing format conversion) to a new texture when a game requests an old texture address with a different format. 2018-08-20 15:20:35 -05:00
Subv f2c2f8c196 Rasterizer: Don't attempt to copy over the old texture's data when doing a format reinterpretation if we're only going to clear the framebuffer. 2018-08-20 15:20:35 -05:00
Subv 076cedb836 Shaders/TEXS: Fixed the component mask in the TEXS instruction. 
Previously we could end up with a TEXS that didn't write any outputs, this was wrong.
 2018-08-19 17:09:40 -05:00
Subv 67da7c7ab8 Shaders/TEXS: Fixed the component mask in the TEXS instruction. 
Previously we could end up with a TEXS that didn't write any outputs, this was wrong.
 2018-08-19 14:00:12 -05:00
Subv 1f92a7cb88 Shader: Implemented the TLD4 and TLD4S opcodes using GLSL's textureGather. 
It is unknown how TLD4S determines the sampler type, more research is needed.
 2018-08-19 12:57:58 -05:00
Subv 18b91924b1 Shader: Use the right sampler type in the TEX, TEXS and TLDS instructions. 
Different sampler types have their parameters in different registers.
 2018-08-19 12:57:54 -05:00
Subv 8b1711cdd5 Shader: Added bitfields for the texture type of the various sampling instructions. 2018-08-19 12:57:51 -05:00
Subv 906f9fb7bf Shaders: Added decodings for TLD4 and TLD4S 2018-08-19 12:57:08 -05:00
Subv d580b54809 Shaders: Added decodings for the LDG and STG instructions. 2018-08-19 00:46:34 -05:00
Subv 67e993fdd3 Shaders: Implemented the gl_FrontFacing input attribute (attr 63). 2018-08-19 00:14:34 -05:00
Subv cdd03fbb45 Shader: Remove an unneeded assert, the negate bit is implemented for conversion instructions. 2018-08-18 14:48:05 -05:00
Subv 175096eff7 GLRasterizer: Implemented instanced vertex arrays. 
Before each draw call, for every enabled vertex array configured as instanced, we take the current instance id and divide it by its configured divisor, then we multiply that by the corresponding stride and increment the start address by the resulting amount. This way we can simulate the vertex array being incremented once per instance without actually using OpenGL's instancing functions.
 2018-08-18 14:42:26 -05:00
Subv 70e99baabe Shader: Implemented the predicate and mode arguments of LOP. 
The mode can be used to set the predicate to true depending on the result of the logic operation. In some cases, this means discarding the result (writing it to register 0xFF (Zero)).

This is used by Super Mario Odyssey.
 2018-08-18 14:36:37 -05:00
Subv c42b8cbdd0 Shaders: Implemented a stack for the SSY/SYNC instructions. 
The SSY instruction pushes an address into the stack, and the SYNC instruction pops it. The current stack depth is 20, we should figure out if this is enough or not.
 2018-08-18 10:48:12 -05:00
Subv a175f7ba29 Shaders: Corrected the 'abs' and 'neg' bit usage in the float arithmetic instructions. 
We should definitely audit our shader generator for more errors like this.
 2018-08-18 10:22:42 -05:00
Subv 64cb9fc8b0 Shader/Conversion: Implemented the negate bit in F2F and I2I instructions. 2018-08-15 09:27:43 -05:00
Subv 237848d417 Shader/I2F: Implemented the negate I2F_C instruction variant. 2018-08-15 09:25:02 -05:00
Subv 61be8e0be3 Shader/F2I: Implemented the negate bit in the I2F instruction 2018-08-15 09:18:55 -05:00
Subv cb60077c0c Shader/F2I: Implemented the F2I_C instruction variant. 2018-08-15 09:16:35 -05:00
Subv e0c412ae9b Shader/F2I: Implemented the negate bit in the F2I instruction. 2018-08-15 09:15:55 -05:00
Subv 1162a49920 Rasterizer: Implemented instanced rendering. 
We keep track of the current instance and update an uniform in the shaders to let them know which instance they are.

Instanced vertex arrays are not yet implemented.
 2018-08-14 22:25:07 -05:00
Subv 21fa6cb72c CPU/Timing: Use an approximated amortized amount of ticks when advancing timing. 
We divide the number of ticks to add by the number of cores (4) to obtain a more or less rough estimate of the actual number of ticks added. This assumes that all 4 cores are doing similar work. Previously we were adding ~4 times the number of ticks, thus making the games think that time was going way too fast.

This lets us bypass certain hangs in some games like Breath of the Wild.

We should modify our CoreTiming to support multiple cores (both running in a single thread, and in multiple host threads).
 2018-08-12 20:41:28 -05:00
Subv a063b51094 Kernel/SVC: Don't reschedule the current core when creating a new thread. 
The current core may have nothing to do with the core where the new thread was scheduled to run. In case it's the same core, then the following PrepareReshedule call will take care of that.
 2018-08-12 20:38:37 -05:00
Subv 42d6bbcb7c Core/HLE: Make the 'reschedule_pending' flag atomic. 
Another thread may write to this variable while the core in question is in the middle of checking for a reschedule request.
 2018-08-12 18:41:12 -05:00
Subv c51eb8b679 CPU/HLE: Lock the HLE mutex before performing a reschedule. 
Another thread might be in the middle of an SVC, thus altering the state of the schedulers.
 2018-08-12 18:41:11 -05:00
Subv 5fe52770ea Kernel/Threads: Lock the HLE mutex when executing the wakeup callback. 
Another thread might be in the middle of a reschedule, thus altering the state of the schedulers.
 2018-08-12 18:41:11 -05:00
Subv cbf854666d Kernel/Thread: Always use the threadsafe option when scheduling wakeups. 
WakeAfterDelay might be called from any host thread, so err on the side of caution and use the thread-safe CoreTiming::ScheduleEventThreadsafe.

Note that CoreTiming is still far from thread-safe, there may be more things we have to work on for it to be up to par with what we want.
 2018-08-12 18:40:56 -05:00
Subv 8f493f43e7 Kernel/Mutex: Don't duplicate threads in the mutex waiter list. 
Exit from AddMutexWaiter early if the thread is already waiting for a mutex owned by the owner thread.

This accounts for the possibility of a thread that is waiting on a condition variable being awakened twice in a row.

Also added more validation asserts.

This should fix one of the random crashes in Breath Of The Wild.
 2018-08-12 16:35:27 -05:00
Subv 45ee826309 GPU/Maxwell3D: Implemented an alternative set of blend factors. 
These are used by nouveau and some games like SMO.
 2018-08-11 20:57:16 -05:00
Subv 8582c5bb3e RasterizerGL: Ignore invalid/unset vertex attributes. 
This should make the es2gears example not crash anymore.
 2018-08-11 20:36:40 -05:00
Subv 5d543d88b9 GPU/Shader: Don't predicate instructions that don't have a predicate field (SSY). 2018-08-11 16:00:14 -05:00
Subv 995c819038 GPU/Shaders: Implemented SSY and SYNC as a way to modify control flow during shader execution. 
SSY sets the target label to jump to when the SYNC instruction is executed.
 2018-08-11 15:55:11 -05:00
Subv 3aebf087c1 MacroInterpreter: Avoid left shifting negative values. 
The branch target is signed, so multiply by 4 instead of left shifting by 2
 2018-07-30 20:38:24 -05:00
Subv 253cd9b5b9 nvhost_gpu: Added checks to ensure we don't read past the end of the entries when handling a GPU command list. 2018-07-30 20:09:13 -05:00
Subv 48df583947 nvhost_ctrl_gpu: Only read the input parameters if they are actually there. 
Passing nullptr to memcpy is undefined behavior.
 2018-07-30 20:08:36 -05:00

Subv a99c559c69 GPU: Use the right texture format for sRGBA framebuffers. 2018-07-25 09:52:39 -05:00
Subv 6c114256ca GPU: Allow the use of Z24S8 as a texture format. 2018-07-25 09:41:24 -05:00
Subv b4ae8432b4 GPU: Implemented the Z32_S8_X24 depth buffer format. 2018-07-24 20:41:40 -05:00
Subv 72cb7ab18b GPU: Allow using Z32 as a texture format. 2018-07-24 19:54:23 -05:00
Subv 1930980a26 GPU: Allow the usage of R8 as a render target format. 2018-07-24 19:49:36 -05:00
Subv 3b77420f15 GPU: Remove the assert that required the CODE_ADDRESS to be 0. 
Games usually just leave it at 0 but nouveau sets it to something else. This already works fine, the assert is useless.
 2018-07-24 13:54:12 -05:00
Subv d10cc9c548 GPU: Implemented the R16 and R16F texture formats. 2018-07-24 13:39:16 -05:00

externals: Update dynarmic to fc6b73bd
 2018-07-22 11:45:47 -05:00
Subv c4bfd25a6a GPU: Implement the NVGPU_IOCTL_CHANNEL_KICKOFF_PB ioctl2 command. 
This behaves quite similarly to the SubmitGPFIFO command. Referenced from Ryujinx.
Many thanks to @gdkchan for investigating this!
 2018-07-21 15:50:02 -05:00
Subv c1cc141fb0 Loader: Only print the module names and addresses if they actually exist. 2018-07-20 19:59:15 -05:00
Subv 196a689d20 CPU: Save and restore the TPIDR_EL0 system register on every context switch. 
Note that there's currently a dynarmic bug preventing this register from being written.
 2018-07-20 19:57:45 -05:00
Subv 34d18dac20 HLE/ACC: Stub IManagerForApplication::GetAccountId to return an error. 
And make IManagerForApplication::CheckAvailability always return false.
Returning a bogus id from GetAccountId causes games to crash on boot.
We should investigate this with a hwtest and either stub it properly or implement it.
 2018-07-20 11:02:25 -05:00
Subv 5bad464f7b HLE/ACC: Return an IProfile that is consistent with what was requested. 
The default username for now is "yuzu".
We should eventually allow the creation of users in the emulator and have the ability to modify their parameters.
 2018-07-19 16:53:42 -05:00
Subv 791d6b8b3a HLE/ACC: Change the default user id to be consistent with what we tell games on startup. 
In IApplicationFunctions::PopLaunchParameter we tell the games that they were launched as user id 1.
 2018-07-19 16:51:55 -05:00
Subv 3c8e295c50 HLE/ACC: Write a single whole user id in ListAllUsers and ListOpenUsers. 
We only emulate a single user id for now.

hle_ipc: Amend usage of buffer_index within one of HLERequestContext's WriteBuffer() overloads
 2018-07-19 14:36:34 -05:00
Subv c1b5369f60 Filesystem: Return EntryType::Directory for the root directory. 
It is unknown if this is correct behavior, but it makes sense and fixes a regression with Stardew Valley.
 2018-07-19 13:11:09 -05:00
Subv 8335e656bb GPU: Added register definitions for the stencil parameters. 2018-07-17 15:00:21 -05:00
Subv a4f321da14 Services/BSD: Corrected the return for StartMonitoring according to SwIPC. 2018-07-14 12:34:07 -05:00
Subv d4a639a08e FileSys: Append the requested path to the filesystem base path in DeleteFile. 
We were trying to delete things in the current directory instead of the actual filesystem directory. This may fix some savedata issues in some games.
 2018-07-14 10:57:22 -05:00
Subv 021731e42a GPU: Always enable the depth write when clearing the depth buffer. 
The GPU ignores that register when clearing, but OpenGL obeys the glDepthMask parameter, so we set the depth mask to GL_TRUE when clearing the depth buffer. It will be restored to the correct value automatically on the next draw call.
 2018-07-14 00:52:23 -05:00
Sebastian Valle d1bd94351c Merge pull request #652 from Subv/fadd32i

Subv 3c86a705ba GPU: Implemented the BC7U texture format. 
Note: Our version of glad exports GL_COMPRESSED_RGBA_BPTC_UNORM as GL_COMPRESSED_RGBA_BPTC_UNORM_ARB, maybe it's time we update it.
 2018-07-07 09:17:48 -05:00
Subv c44c0078cc GPU: Allow using the old NV04 values for the depth test function. 
These seem to be just a valid as the GL token values. Thanks @ReinUsesLisp

This restores graphical output to Disgaea 5
 2018-07-05 13:01:31 -05:00
Subv cc56ecc097 GPU: Implemented the IMNMX shader instruction. 
It's similar to the FMNMX instruction but it works on integers.
 2018-07-04 15:44:37 -05:00
Subv c4268c13c6 GPU: Implemented the F2F 'round' rounding mode. 
It's implemented via the GLSL 'roundEven()' function.
 2018-07-04 15:43:21 -05:00
Subv 56a5e7ba50 GPU: Stub the shader SYNC and DEPBAR instructions. 
It is unknown at this moment if we actually need to do something with these instructions or if the GLSL compiler takes care of that for us.
 2018-07-04 15:29:51 -05:00
Subv 25e08cf116 GPU: Implement the Size_16_16 and Size_10_10_10_2 vertex attribute types. 
Both signed and unsigned variants.
 2018-07-04 15:22:34 -05:00
Subv 36822431cc GPU: Ignore textures that the GLSL compiler deemed unused when binding textures to the shaders. 2018-07-04 15:20:12 -05:00
Subv 673600656c GPU: Corrected the decoding for the TEX shader instruction. 2018-07-04 15:19:20 -05:00
Subv 9ba997d4f0 GPU: Implemented the PSETP shader instruction. 
It's similar to the isetp and fsetp instructions but it works on predicates instead.
 2018-07-04 15:15:03 -05:00
Subv 910af4676c GPU: Implemented the 32 bit float depth buffer format. 2018-07-04 10:42:33 -05:00
Subv 70f55cf738 GPU: Flip the triangle front face winding if the GPU is configured to not flip the triangles. 
OpenGL's default behavior is already correct when the GPU is configured to flip the triangles.

This fixes 1-2 Switch's splash screen.
 2018-07-04 10:26:46 -05:00
Subv 53e622f91d GPU: Only configure the used framebuffers during clear. 
Don't try to configure the color buffer if it is not being cleared, it may not be completely valid at this point.
 2018-07-03 22:32:59 -05:00
Subv bb62c6dde3 GPU: Factor out the framebuffer configuration code for both Clear and Draw commands. 2018-07-03 16:56:47 -05:00
Subv 20afd1187d GPU: Support clears that don't clear the color buffer. 2018-07-03 16:56:47 -05:00
