2013-12-20drm/radeon: program DCE2 audio dto just like DCE3Alex Deucher
commit 55d4e020fb8ddd3896a8cd3351028f5c3a2c4bd3 upstream. Seems to work like the DCE3 version despite what the register spec says. bug: https://bugs.freedesktop.org/show_bug.cgi?id=71975 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-12-08drm/radeon/audio: correct ACR tablePierre Ossman
commit 3e71985f2439d8c4090dc2820e497e6f3d72dcff upstream. The values were taken from the HDMI spec, but they assumed exact x/1.001 clocks. Since we round the clocks, we also need to calculate different N and CTS values. Note that the N for 25.2/1.001 MHz at 44.1 kHz audio is out of spec. Hopefully this mode is rarely used and/or HDMI sinks tolerate overly large values of N. bug: https://bugs.freedesktop.org/show_bug.cgi?id=69675 Signed-off-by: Pierre Ossman <pierre@ossman.eu> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: Josh Boyer <jwboyer@fedoraproject.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-12-08drm/radeon/audio: improve ACR calculationPierre Ossman
commit a2098250fbda149cfad9e626afe80abe3b21e574 upstream. In order to have any realistic chance of calculating proper ACR values, we need to be able to calculate both N and CTS, not just CTS. We still aim for the ideal N as specified in the HDMI spec though. bug: https://bugs.freedesktop.org/show_bug.cgi?id=69675 Signed-off-by: Pierre Ossman <pierre@ossman.eu> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: Josh Boyer <jwboyer@fedoraproject.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-12-04drm/radeon: use hw generated CTS/N values for audioAlex Deucher
commit ee0fec312a1c4e26f255955da942562cd8908a4b upstream. Use the hw generated values rather than calculating them in the driver. There may be some older r6xx asics where this doesn't work correctly.

commit e7d12c2f98ae1e68c7298e5028048d150fa553a1 upstream. The drm code that calculates the 1001 clocks rounds up rather than truncating. This allows the table to match properly on those modes.

2013-08-14drm/radeon: select audio dto based on encoder id for DCE3Alex Deucher
commit e1accbf0543eecfdb161131208c3dfefee22d61f upstream. There are two audio dtos on radeon asics that you can select between. Normally, dto0 is used for hdmi and dto1 for DP, but it seems that the dto is somehow tied to the encoders on DCE3 asics. fixes: https://bugs.freedesktop.org/show_bug.cgi?id=67435 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-07-25drm/radeon: fix AVI infoframe generationAlex Deucher
commit f100380ecd8287b0909d3c5694784adc46e78a4a upstream. - remove adding 2 to checksum, this is incorrect. This was incorrectly introduced in: 92db7f6c860b8190571a9dc1fcbc16d003422fe8 http://lists.freedesktop.org/archives/dri-devel/2011-December/017717.html However, the off by 2 was due to adding the version twice. From the examples in the URL above: [Rafał Miłecki][RV620] fglrx: 0x7454: 00 A8 5E 79 R600_HDMI_VIDEOINFOFRAME_0 0x7458: 00 28 00 10 R600_HDMI_VIDEOINFOFRAME_1 0x745C: 00 48 00 28 R600_HDMI_VIDEOINFOFRAME_2 0x7460: 02 00 00 48 R600_HDMI_VIDEOINFOFRAME_3 =================== (0x82 + 0x2 + 0xD) + 0x1F8 = 0x289 -0x289 = 0x77 However, the payload sum is not 0x1f8, it's 0x1f6. 00 + A8 + 5E + 00 + 00 + 28 + 00 + 10 + 00 + 48 + 00 + 28 + 00 + 48 = 0x1f6 Bits 25:24 of HDMI_VIDEOINFOFRAME_3 are the packet version, not part of the payload. So the total would be: (0x82 + 0x2 + 0xD) + 0x1f6 = 0x287 -0x287 = 0x79 - properly emit the AVI infoframe version. This was not being emitted previous which is probably what caused the issue above. This should fix blank screen when HDMI audio is enabled on certain monitors.

Pull drm merge (part 1) from Dave Airlie: "So first of all my tree and uapi stuff has a conflict mess, its my fault as the nouveau stuff didn't hit -next as were trying to rebase regressions out of it before we merged. Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked."

2012-06-21drm/radeon: apply Murphy's law to the kms irq code v3Christian Koenig
1. It is really dangerous to have more than one spinlock protecting the same information. 2. radeon_irq_set sometimes wasn't called with lock protection, so it can happen that more than one CPU would tamper with the irq regs at the same time. 3. 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.
