| | | | | | | | | | | | | KMS support is out and stable for a couple of years now and the userspace code has deprecated or abandoned the old UMS interface.

| | | | | | | | | | | | Just refactoring to make the next patche simpler. Now all indirect register access in the new modesetting driver should go through the r100_mm_(w|r)reg fucntions.

These GPUs are typically wired to the laptop panel and VGA ports via a multiplexer unit which is controlled via ACPI methods. 4 combinations of systems typically exist - with 2 ACPI methods. Intel/ATI - Lenovo W500/T500 - use ATPX ACPI method ATI/ATI - some ASUS - use ATPX ACPI Method Intel/Nvidia - - use _DSM ACPI method Nvidia/Nvidia - - use _DSM ACPI method. TODO: This patch adds support for the ATPX method and initial bits for the _DSM methods that need to written by someone with access to the hardware. Add a proper non-debugfs interface - need to get some proper testing first. v2: add power up/down support for both devices on W500 puts i915/radeon into D3 and cuts power to radeon. v3: redo probing methods, no DMI list, drm devices call to register with switcheroo, it tries to find an ATPX method on any device and once there is two devices + ATPX it inits the switcher. v4: ATPX msg handling using buffers - should work on more machines v5: rearchitect after more mjg59 discussion - move ATPX handling to radeon driver. v6: add file headers + initial nouveau bits (to be filled out). v7: merge delayed switcher code. v8: avoid suspend/resume of gpu that is off v9: rearchitect - mjg59 is always right. - move all ATPX code to radeon, should allow simpler DSM also proper ATRM handling v10: add ATRM support for radeon BIOS, add mutex to lock vgasr_priv v11: fix bug in resuming Intel for 2nd time. v12: start fixing up nvidia code blindly. v13: blindly guess at finishing nvidia code v14: remove radeon audio hacks - fix up intel resume more like upstream v15: clean up printks + remove unnecessary igd/dis pointers mount debugfs /sys/kernel/debug/vgaswitcheroo/switch - should exist if ATPX detected + 2 cards. DIS - immediate change to discrete IGD - immediate change to IGD DDIS - delayed change to discrete DIGD - delayed change to IGD ON - turn on not in use OFF - turn off not in use Tested on W500 (Intel/ATI) and T500 (Intel/ATI) Signed-off-by: Dave Airlie <airlied@redhat.com>

Now mesa used to always emit clears after emitting state, since the radeon mesa driver was refactored a year or more ago, it was found it could generate a clear request without ever sending any setup state to the card. So the clear would attempt to clear the depth buffer at 0x0, which would overwrite main memory at this point. fs corruption ensues. Also once one app did this correctly, it would never get set back to 0 making this messy to reproduce. The kernel should block this from happening as mesa runs without privs, though it does require the user be connected to the current running X session. This patch implements a check to make sure the depth offset has been set before a depth clear occurs and if it finds one it prints a warning and ignores the depth clear request. There is also a mesa fix to avoid sending the badness going into mesa. This only affects r100/r200 GPUs in user modesetting mode. Signed-off-by: Dave Airlie <airlied@redhat.com>

Allocation of single large block of memory may fail under memory presure. drm_buffer object can hold one large block of data in multiple independ pages which preents alloation failures. This patch converts all access to command stream to use drm_buffer interface. All direct access to array has to go tough drm_buffer functions to get correct pointer. Outputting the command stream to ring buffer needs to be awear of the split nature of drm_buffer. The output operation requires the new OUT_RING_DRM_BUFFER.

| * drm/radeon/kms: r600/r700 command stream checkerJerome Glisse2010-02-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add cs checker to r600/r700 hw. Command stream checking will rewrite some of the cs value in order to restrict GPU access to BO size. This doesn't break old userspace but just enforce safe value. It should break any things that was using the r600/r700 cs ioctl to do forbidden things (malicious software), though we are not aware of such things. Here is the list of thing we check : - enforcing resource size - enforcing color buffer slice tile max, will restrict cb access - enforcing db buffer slice tile max, will restrict db access We don't check for shader bigger than the BO in which they are supposed to be, such use would lead to GPU lockup and is harmless from security POV, as far as we can tell (note that even checking for this wouldn't prevent someone to write bogus shader that lead to lockup). This patch has received as much testing as humanly possible with old userspace to check that it didn't break such configuration. However not all the applications out there were tested, thus it might broke some odd, rare applications.

* drm/radeon/kms: Add support for interrupts on r6xx/r7xx chips (v3)Alex Deucher2009-12-021-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | This enables the use of interrupts on r6xx/r7xx hardware. Interrupts are implemented via a ring buffer. The GPU adds interrupts vectors to the ring and the host reads them off in the interrupt handler. The interrupt controller requires firmware like the CP. This firmware must be installed and accessble to the firmware loader for interrupts to function. MSIs don't seem to work on my RS780. They work fine on all my discrete cards. I'm not sure about other RS780s or RS880s. I've disabled MSIs on RS780 and RS880, but it would probably be worth checking on some other systems. v2 - fix some checkpatch.pl problems; re-read the disp int status reg if we restart the ih; v3 - remove the irq handler if r600_irq_init() fails; remove spinlock in r600_ih_ring_fini(); move ih rb overflow check to r600_get_ih_wptr(); move irq ack to separate function; Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

The r600 TTM support is quite basic and still needs more work esp around using interrupts, but the polled fencing should work okay for now. Also currently TTM is using memcpy to do VRAM moves, the code is here to use a 3D blit to do this, but isn't fully debugged yet.

However, the code unconditionally uses DRM_{READ,WRITE}32() (and thus readl() and writel()) to access it. Basically, if RADEON_IS_AGP then it's ioremap()'d memory else it's vmalloc'd memory. Adjust all of the ring_rptr access code as needed. While we're here, kill the 'scratch' pointer in drm_radeon_private. It's only used in the one place where it is initialized. Signed-off-by: David S.

* drm: move to kref per-master structures.Dave Airlie2008-12-291-3/+11
| | | | | | | | | | | | | | | | This is step one towards having multiple masters sharing a drm device in order to get fast-user-switching to work. It splits out the information associated with the drm master into a separate kref counted structure, and allocates this when a master opens the device node. It also allows the current master to abdicate (say while VT switched), and a new master to take over the hardware. It moves the Intel and radeon drivers to using the sarea from within the new master structures. Signed-off-by: Dave Airlie <airlied@redhat.com>

* drm: Rework vblank-wait handling to allow interrupt reduction.Jesse Barnes2008-10-181-10/+17
| | | | | | | | | | | | | | | Previously, drivers supporting vblank interrupt waits would run the interrupt all the time, or all the time that any 3d client was running, preventing the CPU from sleeping for long when the system was otherwise idle. Now, interrupts are disabled any time that no client is waiting on a vblank event. The new method uses vblank counters on the chipsets when the interrupts are turned off, rather than counting interrupts, so that we can continue to present accurate vblank numbers.

* radeon: fix some hard lockups on r3/4/500sJerome Glisse2008-08-251-7/+12
| | | | | | | | This patch should fix hard lockup and convert them in softlockup (ie you can ssh the box but the gpu is busted and we are waiting in loop for it to come back to reason). Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: reorganise drm tree to be more future proof.Dave Airlie2008-07-141-0/+1406
With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: Dave Airlie <airlied@redhat.com>
