The Cell Broadband Engine Programming Handbook has this to say on the subject: The first implementation of the Cell Broadband Engine Architecture (CBEA) (the CBE processor) supports instructions with a graphics rounding mode. This mode allows programs written with vector/SIMD multimedia extension instructions to produce floating-point results that are equivalent in precision to those written in the SPU instruction set. In this mode, as in the SPU environment, the default rounding mode is round to zero, denormals are treated as zero, and there are no infinities or NaNs. | The Cell Broadband Engine Programming Handbook has this to say on the subject: The first implementation of the Cell Broadband Engine Architecture (CBEA) (the CBE processor) supports instructions with a graphics rounding mode.

Notes: | |||
Valid values for bus_id and dev_id can be obtained from the repository (see [[HV_Syscall_Reference#lv1_get_repository_node_value|lv1_get_repository_node_value]]). | |||
Once open, functions such as [[HV_Syscall_Reference#lv1_map_device_mmio_region|lv1_map_device_mmio_region]] and [[HV_Syscall_Reference#lv1_allocate_device_dma_region|lv1_allocate_device_dma_region]] can be used to map the device into memory. | |||
The value of R5 does not seem to affect the outcome of the call (powers of 2 in the 64 bit range were tested). One reason for the flag could be to indicate whether to open the device in shared mode or not (and thus prevent the LV1_BUSY return code). | |||

Notes: | Notes: When the device is little endian, the mode must be set to 8 bit for 8 bit DMA to work as expected, otherwise the bytes will be read/written in the wrong order. OTOH, this mode requires that 16 and 32-bit values are byte-swapped by the CPU since they will appear as little endian in memory. | ||

== | Info taken from kboot-10\dl\linux-2.6.16\sound\powerpc\snd_ps3pf.c (kboot-20061208) where the audio front-end registers are mapped into memory. Two calls to lv1_gpu_device_map are performed, the first when dev_id = 1, to obtain the audio interrupt (Audio IRQ Outlet) and a second time when dev_id = 2 to obtain a mapping of the register block (Audio Registers). | ||
lpar_addr is a virtual address, created by the Hypervisor. Multiple calls to lv1_gpu_device_map with the same dev_id return successfully, but the lpar_address returned for each is different (if there have been no intermediary lv1_gpu_device_unmap calls). These various virtual lpar_addr values all alias the same physical location in memory. | |||

It is interesting that when dev_id = 4, LV1_ILLEGAL_PARAMETER_VALUE is returned with lpar_addr and lpar_size set to the values returned from the previous call - for the first call when dev_id = 0, values also appear to be set (though these could be garbage values) | |||
=== | ===== Devices 1 & 2 ===== | ||
dev_id 1 gives a location used to process IRQ’s from the audio and dev_id 2 gives the base address of the Audio Hardware registers. From published Sony documents (http://www.watch.impress.co.jp/game/docs/20060329/3dps303.htm), Audio is believed to be on the RSX, this call seems to confirm that. Access to the audio after this mapping call (it would appear) bypasses the Hypervisor and occurs directly on the RSX hardware. 3,5,6,7,8 are currently unknown. Presumably 0 and 4 are otherwise valid parameters blocked by the Hypervisor for OtherOS (ie, they may function for Games) otherwise I would have expected a return result of -20 for them. So rather than just being a bridge for audio into HDMI, it is for all audio. | |||
Also interesting is that the GPU version number returned by [[HV_Syscall_Reference#lv1_gpu_context_allocate|lv1_gpu_context_allocate]] appears at address 0×10 in the device 1 dump, though this of course may be complete coincidence. | |||
===== Device 7 ===== | |||
dev_id 7 appears to be a video device. It is not possible to map the entire reported memory space (0×10000), only areas 0×0000 to 0x0fff and 0×2000 to 0x2fff (discovered via laborious trial and error testing, mapping other areas causes the PS3 to hang without warning). In both mappable areas, the current screen resolution can be seen at locations 0×200 and 0×210. Changes to the ps3 video mode (e.g. using the ps3videomode utility) can be observed in the mapped areas, but modifying the values directly does not affect the screen resolution. Although both areas contain different values, there appear to be parts in common, as changing the values at 0×200 and 0×210 directly in one area also causes the same values in the other area to change. | |||
Given the screen resolution connection, it could be possible that this device is a mapping of the GPU display heads: | |||
*Out of 16Kb, only two areas are mappable (= number of accessible display heads) | |||
*Mappable areas are 2Kb apart → 8 total display heads (= size of display heads array returned by [[HV_Syscall_Reference#lv1_gpu_context_allocate|lv1_gpu_context_allocate]]) | |||
===== Device 8 ===== | |||
dev_id 8 appears to be a mapping of video RAM at offset 0x0ff10000. This region of video memory is referenced by RSX DMA objects but its purpose is unknown. | |||
---- | ---- | ||

Notes: | |||
ddr_size accepts values (0..252) * 2^20 - values not divisible by 2^20 (1 MB) and above the range result in a return value of -17 (LV1_ILLEGAL_PARAMETER_VALUE). [Verified by Strontium Dog on an AU PS3 V1.5 firmware] | |||
Bits 52-63 of ddr_size seem to be ignored or correspond to flags. The lower bits correspond to the amount of allocated video RAM. A call to [[HV_Syscall_Reference#lv1_gpu_context_allocate|lv1_gpu_context_allocate]] using the returned memory_handle will create a RSX DMA object handle 0xfeed0000 corresponding to the region of allocated memory. Multiple calls to [[HV_Syscall_Reference#lv1_gpu_memory_allocate|lv1_gpu_memory_allocate]] with non-zero ddr_size will change the start of this region. The DMA object limit is set to ddr_size - 1. Before FW 2.1, a ddr_size of 0 was accepted, in which case a DMA object starting at zero and of limit 0xffffffff was created. Note that in this case, the start of this region is always zero even if previous calls to [[HV_Syscall_Reference#lv1_gpu_memory_allocate|lv1_gpu_memory_allocate]] with non-zero ddr_size were performed. As of FW 2.1 and above, a zero ddr_size is not accepted anymore. | |||
Parameters r4-r7 are unknown. Maximum values for these parameters are respectively 512kB, 3075kB, 15 and 8. They refer to shared scarce resources, as allocations are retained across multiple calls to [[HV_Syscall_Reference#lv1_gpu_memory_allocate|lv1_gpu_memory_allocate]]. When attached to a context during [[HV_Syscall_Reference#lv1_gpu_context_allocate|lv1_gpu_context_allocate]], the values of these parameters are reported in the lpar_driver_info structure of the context. | |||
Cell separates multiple OS into Logical Partitions (lpar) described at http://research.scea.com/research/html/CellGDC05/13.html. PS3 GPU memory is referred to as DDR (or GDDR) whereas system memory is XDR. 256 MB of each are installed in PS3 though only XDR is currently available for use by OtherOS. | |||
To make use of the allocated DDR ddr_lpar needs to be transformed into a usable address using: | |||
ddr_address = ioremap_flags(ddr_lpar, ddr_size, _PAGE_NO_CACHE); | |||
Be aware that the memory that holds the physical GPU frame buffer is not allocated by the Kernel, just used. So on the first call to this, some or all of the memory you request (depending on now much you request) may be actually used as the frame buffer. You will know this, because your writes to memory will mysteriously disappear up to 20ms after you perform them. Note that direct access to video ram is very slow (~10MB/s). | |||

This function creates a mapping in GPU address space so that the RSX can access system RAM. The Kernel uses it to associate the virtual framebuffer residing in system RAM to the GPU, so that so that transfers can be initiated by the RSX from the system RAM to the video RAM using the [[HV_Syscall_Reference#lv1_gpu_context_attribute|lv1_gpu_context_attribute]]:fb_blit() call. | |||
Comments: | |||
It was previously suspected that GPU_IOIF was the address of GPU MMIO registers. However GPU_IOIF is a GPU address, not a lpar address, and therefore has no meaning on the Linux side, and cannot be directly mapped from the Linux address space. Reserving the memory block (using request_mem_region) and mapping (using ioremap) results in a block of memory that is used by Linux (nothing resembling IO registers was observed whilst single frame stepping a gfx demo). [was: As you’ve previously discovered that the top of RAM is 0x0e00 0000, GPU_IOIF here is 16Mb below that. That’s typically the size of the a graphics card PCI IO region on a PC, so given the name, I’d strongly suggest it’s not GPU memory that’s being mapped but the GPU IO registers. Although why this address range would overlap with RAM is a mystery.] | |||
GPU_IOIF was successfully set to other values (0×00000000, 0×02000000, 0×04000000) with Linux booting and displaying correctly. A value of 0x0f000000 causes the PS3 to hang (need to retest 0x0e0000000) | |||
Although it looks like GPU_IOIF would overlap video RAM, the RSX differentiates between the two by associating different DMA objects to the source and destination of the blit. The source is associated with DMA object handle 0xfeed0001 which targets system memory, while the destination is associated with DMA object handle 0xfeed0000 which targets video memory. This has been observed by analysing the FIFO commands sent to the GPU by the hypervisor during the [[HV_Syscall_Reference#lv1_gpu_context_attribute|lv1_gpu_context_attribute]]:fb_setup() and [[HV_Syscall_Reference#lv1_gpu_context_attribute|lv1_gpu_context_attribute]]:fb_blit() calls. | |||
It seems a call to [[HV_Syscall_Reference#lv1_gpu_context_iomap|lv1_gpu_context_iomap]](handle, bus_addr, xdr_lpar, size, flags) is equivalent to a series of call to [[HV_Syscall_Reference#lv1_put_iopte|lv1_put_iopte]]: | |||
===== | int i; | ||
int context_number; /* derived from handle, 1st allocated context 0, 2nd allocated context 1, etc... */ | |||
for (i = 0; i < size; i += 1024 * 1024) { | |||
lv1_put_iopte(0, /* IO ASID */ | |||
((0x08ULL + context_number) << 28) | bus_addr) + i, /* IO address */ | |||
xdr_lpar + i, /* Logical Partition address */ | |||
1, /* PS3_AUDIO_IOID, actually RSX IOID */ | |||
flags); | |||

The code in the kernel does all manner of things to actually reboot, including sending vuart messages to some other process running in a different LPAR. I haven’t investigated enough to see exactly what it does, but calling lv1_panic(0) from my my code in the hypervisor causes a panic with the red light flashing until the power button is pressed whereas the kernel’s shutdown code doesn’t. | The code in the kernel does all manner of things to actually reboot, including sending vuart messages to some other process running in a different LPAR.
