2013-08-30radeon kms: fix uninitialised hotplug work usage in r100_irq_process()Sergey Senozhatsky
Commit a01c34f72e7cd2624570818f579b5ab464f93de2 (radeon kms: do not flush uninitialized hotplug work) moved work initialisation phase to the last step of radeon_irq_kms_init(). Meelis Roos reported that this causes problems on his machine because drm_irq_install() uses hotplug work on r100. hotplug work flushed in radeon_irq_kms_fini(), with two possible cases: -- radeon_irq_kms_fini() call after successful radeon_irq_kms_init() -- radeon_irq_kms_fini() call after unsuccessful (or not called at all) radeon_irq_kms_init() The latter one causes flush work on uninitialised hotplug work. Move work initialisation before drm_irq_install(), but keep existing agreement to flush hotplug work in radeon_irq_kms_fini() only for `irq.installed' (successful radeon_irq_kms_init()) case.

2013-07-15radeon kms: do not flush uninitialized hotplug workSergey Senozhatsky
Fix a warning from lockdep caused by calling flush_work() for uninitialized hotplug work. Initialize hotplug_work, audio_work and reset_work upon successful radeon_irq_kms_init() completion and thus perform hotplug flush_work only when rdev->irq.installed is true.

2013-06-25drm/radeon: add a reset work handlerAlex Deucher
New asics support non-privileged IBs. This allows us to skip IB checking in the driver since the hardware will check the command buffers for us. When using non-privileged IBs, if the CP encounters an illegal register in the command stream, it will halt and generate an interrupt. The CP needs to be reset to continue. For now just do a full GPU reset when this happens. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant and the regular flushes guarantee that the work item is not pending or running on any CPU on return, so there's no reason to use the sync flushes at all and they're going away.

1.

The pm.gui_idle variable was assuming that the 3D engine wasn't becoming idle between testing the register and setting the variable. So just remove it and test the register directly. v2: Also handle the hpd irq code the same way. v3: Rename hpd parameter for clarification.

2012-05-07Merge tag 'v3.4-rc6' into drm-intel-nextDaniel Vetter
Conflicts: drivers/gpu/drm/i915/intel_display.c Ok, this is a fun story of git totally messing things up. There /shouldn't/ be any conflict in here, because the fixes in -rc6 do only touch functions that have not been changed in -next. The offending commits in drm-next are 14415745b2..1fa611065 which simply move a few functions from intel_display.c to intel_pm.c. The problem seems to be that git diff gets completely confused: $ git diff 14415745b2..1fa611065 is a nice mess in intel_display.c, and the diff leaks into totally unrelated functions, whereas $git diff --minimal 14415745b2..1fa611065 is exactly what we want. Unfortunately there seems to be no way to teach similar smarts to the merge diff and conflict generation code, because with the minimal diff there really shouldn't be any conflicts. For added hilarity, every time something in that area changes the + and - lines in the diff move around like crazy, again resulting in new conflicts. So I fear this mess will stay with us for a little longer (and might result in another backmerge down the road). Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2011-11-03drm/radeon/kms: add MSI module parameterAlex Deucher
Allow the user to override whether MSIs are enabled or not on supported ASICs. MSIs are disabled by default on IGP chips as they tend not to work. However certain IGP chips only seem to work with MSIs enabled. I suspect this is a chipset or bios issue, but I'm not sure what the proper fix is. This will at least make diagnosing and working around the problem much easier.

hard-coded value 6 radeon_driver_irq_preinstall_kms and radeon_driver_irq_uninstall_kms hard code the loop to 6 which happens to be the current maximum number of crtcs and hpd pins; if one day an ASIC with more crtcs (or hpd pins) comes out, this is a trouble waiting to happen. introduce constants for maximum CRTC count, maximum HPD pins count and maximum HDMI blocks count (per FIXME in radeon_irq structure) and correct the loops in radeon_driver_irq_preinstall_kms and radeon_driver_irq_uninstall_kms v2: take care of goofs pointed out by Alex Deucher Signed-off-by: Ilija Hadzic <ihadzic@research.bell-labs.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2011-01-06drm/radeon: use system_wq instead of dev_priv->wqTejun Heo
With cmwq, there's no reason for radeon to use a dedicated workqueue. Drop dev_priv->wq and use system_wq instead. Because radeon_driver_irq_uninstall_kms() may be called from unsleepable context, the work items can't be flushed from there. Instead, init and flush from radeon_irq_kms_init/fini(). While at it, simplify canceling/flushing of rdev->pm.dynpm_idle_work. Always initialize and sync cancel instead of being unnecessarily smart about it.

2010-04-07drm/kms/fb: add polling support for when nothing is connected.Dave Airlie
When we are running in a headless environment we have no idea what output the user might plug in later, we only have hotplug detect from the digital outputs. So if we detect no connected outputs at initialisation, start a slow work operation to poll every 5 seconds for an output. this is only hooked up for radeon so far, on hw where we have full hotplug detection there is no need for this.

2010-04-07drm/fb: fix fbdev object model + cleanup properly.Dave Airlie
The fbdev layer in the kms code should act like a consumer of the kms services and avoid having relying on information being store in the kms core structures in order for it to work. This patch a) removes the info pointer/psuedo palette from the core drm_framebuffer structure and moves it to the fbdev helper layer, it also removes the core drm keeping a list of kernel kms fbdevs. b) migrated all the fb helper functions out of the crtc helper file into the fb helper file. c) pushed the fb probing/hotplug control into the driver d) makes the surface sizes into a structure for ease of passing This changes the intel/radeon/nouveau drivers to use the new helper.

2009-12-02drm/radeon/kms: Add support for interrupts on r6xx/r7xx chips (v3)Alex Deucher
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>

2009-06-15drm/radeon: introduce kernel modesetting for radeon hardwareJerome Glisse
Add kernel modesetting support to radeon driver, use the ttm memory manager to manage memory and DRM/GEM to provide userspace API. In order to avoid backward compatibility issue and to allow clean design and code the radeon kernel modesetting use different code path than old radeon/drm driver. When kernel modesetting is enabled the IOCTL of radeon/drm driver are considered as invalid and an error message is printed in the log and they return failure. KMS enabled userspace will use new API to talk with the radeon/drm driver. The new API provide functions to create/destroy/share/mmap buffer object which are then managed by the kernel memory manager (here TTM). In order to submit command to the GPU the userspace provide a buffer holding the command stream, along this buffer userspace have to provide a list of buffer object used by the command stream. The kernel radeon driver will then place buffer in GPU accessible memory and will update command stream to reflect the position of the different buffers. The kernel will also perform security check on command stream provided by the user, we want to catch and forbid any illegal use of the GPU such as DMA into random system memory or into memory not owned by the process supplying the command stream. This part of the code is still incomplete and this why we propose that patch as a staging driver addition, future security might forbid current experimental userspace to run. This code support the following hardware : R1XX,R2XX,R3XX,R4XX,R5XX (radeon up to X1950). Works is underway to provide support for R6XX, R7XX and newer hardware (radeon from HD2XXX to HD4XXX).
