> radeon 0000:01:00.0: bo fffff801f3ee2c00 va 0x00000000 conflict with (bo fffff801f3ee3000 0x00800000 0x00802000)
Looks like the Mesa radeon winsys is not assigning GPU virtual memory addresses
correctly (0x00000000 is not a valid virtual address).
You might have better luck with that with current Mesa Git master, but note
that the Mesa radeonsi driver needs a lot of work before it has any chance of
working correctly on big endian hosts.

Michel Dänzer thk for your answer ,you means that the Mesa radeonsi
drivers cannot work well on big endian hosts? Now ,I am read the Mesa codes and
analysis kernel code.the bo_object can create , but it not allocate virtual
space in the userspace.I am not cleaner for GEM/TTM ,and the docs is lacking. I
must analysis the code .

The radeonsi driver currently isn't very well tested on big endian hosts. In
theory it should work, but that doesn't mean there might be a lot of bugs.

I test the newest Mesa(10.2.5), The problem is still existing.
It isn't test very well on big-endian hosts , That means it can work? I never
analysis the mesa code, The code it too more, and haven't docs, Could you give
me some docs? Or give me some ideals? how to alter this code, pls give me a
direction.
Thk.

Actually, it most definitely can't work right now. Just for one thing, every
memory access by shaders (for constants, resource descriptors, ...) currently
can't work correctly on big endian hosts.

FWIW, the failure to assign a valid virtual address is probably an endianness
bug in the virtual memory related code in
src/gallium/winsys/radeon/drm/radeon_drm_bo.c, e.g. in radeon_bomgr_find_va(),
or maybe in the corresponding kernel code.

Our system PAGE_SIZE is 8k, but the GPU PAGE_SIZE is 4k. I have changed the
mesa radeonsi driver memory 8K alignment . So, the virtual address allocate
conflict disappear . But the new problem is come out .
The log message is :

Don't we need to endian-swap the whole IB for big endian?

That depends on which engine you use. IIRC the CP, DMA and UVD till SI can do
endian swap in hardware, but the support got removed for DMA with CIK.
VCE never could do it.

SDMA on CIK can still do endian swaps for IBs.

Than that was another engine, anyway you guys should test without the DMA
initially to rule out any problems.
Basically first try to get the most simple use case working, e.g. X with just
glxgears.

The simplest app I used for the initial radeonsi driver bringup was the Mesa
demo egltri_screen.

bigend
This patch is about virtual space conflict . But this change has been fix in
the mesa-20140607(the version is 10.1.5) ; The new mesa version have a new
problem in our machine .
in founction
struct pipe_resource *r600_resource_create_common(struct pipe_screen *screen,
const struct pipe_resource
*templ)
{
if (templ->target == PIPE_BUFFER) {
return r600_buffer_create(screen, templ, 8192); // original
value is 4096 chen changed 2014-8-19
} else {
return r600_texture_create(screen, templ);
}
}
So, that the virtual address space conflict is disappear.
I am seeing your patch .
https://bugs.freedesktop.org/attachment.cgi?id=104877&action=edit
but i cannot find the "si_update_vertex_buffers" function in our mesa version.
thinks for your help . i will do many test in our machine.

He was talking about the DMA engine on the GPU, which can be disabled by
setting this environment variable prior to running any apps:
R600_DEBUG=nodma
It can also be used to disable DMA for a specific app.

Use CPU page size instead of hardcoding 4096
Does this patch instead of your changes fix the virtual address allocation?

Please use Mesa Git master. Once we have a set of fixes, we can consider
backporting them to stable branches, but they have to be on master first.

My 'Use CPU page size instead of hardcoding 4096' patch should encompass both
changes you mentioned before. What other changes do you need for that?

As discussed before, can you try running a simpler app which doesn't need X,
e.g. egltri_screen from the mesa/demos repository?

Some place in mesa code you are still useing 4096 .
I am setting environment EGL_LOG_LEVEL=debug EGL_PLATFORM=drm R600_DEBUG=nodma
, and I am running egltri_screen. There havn't a tringle display in the
screen center. the message info as follow :
libEGL debug: Native platform type: drm (environment overwrite)
libEGL debug: EGL search path is /usr/lib64/egl
libEGL debug: added egl_dri2 to module array
libEGL debug: the best driver is DRI2
EGL_VERSION = 1.4 (DRI2)
libEGL debug: attribute 0x3033 has an invalid value 0x8
libEGL debug: EGL user error 0x3004 (EGL_BAD_ATTRIBUTE) in eglChooseConfig
EGLUT: failed to choose a config

Please be more specific. Do you still need the change you described in comment
17, or something else?
> libEGL debug: attribute 0x3033 has an invalid value 0x8

Looks like maybe your Mesa build picked up a non-Mesa EGL/eglext.h which
doesn't pull in eglmesaext.h, so EGL_MESA_screen_surface isn't defined in
src/egl/main/eglconfig.c .

Sorry , I am not clean about you saying . Do you means is that the
eglmesaext.h(PATH:include/EGL/eglmesaext.h) need including EGL/eglext.h file?
I change it , but not help.
or , I add EGL_MESA_screen_surface define in src/egl/main/eglconfig.c
#define EGL_MESA_screen_surface 1 .
the problem didn't solved.

I am so sorry, i made a mistake . I am configure mesa no --enable-gallium-egl
options, I rebuild my mesa. The egltri_screen program can run in my system, But
the colourized triangle is didn't show in my machine screen. It is only a white
screen for a few minutes.
radeon: The kernel rejected CS, see dmesg for more information ,but any message
display in dmesg.
the message is follow:

My system is 64bits and big-endian. It is means that the radeinsi driver send a

That shouldn't be necessary, the kernel sets up the hardware to byte-swap the
ring/indirect buffer commands on the fly.
Basically, you need to find out why the radeon_cs_ioctl() function in the
kernel returns a non-0 value. Enabling DRM debugging output via
/sys/module/drm/parameters/debug may help, or you may have to add more
debugging printks to narrow down where it's coming from.

>>radeon: The kernel rejected CS, see dmesg for more information
This error is showed in the drm_ioctl function.The part code show as follow:
468 if (cmd & IOC_OUT) { //error place,
469 printk(KERN_EMERG "cmd & IOC_OUT\n");
470 if (copy_to_user((void __user *)arg, kdata,
471 usize) != 0){
472 printk(KERN_EMERG "cmd & IOC_OUT error\n");
473 retcode = -EFAULT;
474 }
475 }
The copy_from_user havn't error, So the error is cause by parameter.
Or, PAGE_SIZE cause it ?

No, as I said in comment 31, it comes from somewhere inside radeon_cs_ioctl()
AFAICT.
