In radeon_device_init, set the need_dma32 flag for Cedar chips (e.g. FirePro 2270). This fixes, or at least works around, a bug on PowerPC exposed by last year's commits 8e3f1b1d8255105f31556aacf8aeb6071b00d469 (Russell Currey) and 253fd51e2f533552ae35a0c661705da6c4842c1b (Alistair Popple) which enabled the 64-bit DMA iommu bypass.

The output poll worker meanwhile calls pm_runtime_get_sync() in radeon's ->detect hooks, which waits for the ongoing suspend to finish, causing a deadlock. Fix by not acquiring a runtime PM ref if the ->detect hooks are called in the output poll worker's context. This is safe because the poll worker is only enabled while runtime active and we know that ->runtime_suspend waits for it to finish.

Nouveau only exposes support for XBGR2101010. Prior to the atomic conversion, drm would pass in the wrong format in the framebuffer, but it was always ignored -- both userspace (xf86-video-nouveau) and the kernel driver agreed on the layout, so the fact that the format was wrong didn't matter. With the atomic conversion, nouveau all of a sudden started caring about the exact format, and so the previously-working code in xf86-video-nouveau no longer functioned since the (internally-assigned) format from the addfb ioctl was wrong. This change adds infrastructure to allow a drm driver to specify that it prefers the XBGR format variant for the addfb ioctl, and makes nouveau's nv50 display driver set it. (Prior gens had no support for 30bpp at all.)

The output poll worker meanwhile calls pm_runtime_get_sync() in nouveau_connector_detect() which waits for the ongoing suspend to finish, causing a deadlock. Fix by not acquiring a runtime PM ref if nouveau_connector_detect() is called in the output poll worker's context. This is safe because the poll worker is only enabled while runtime active and we know that ->runtime_suspend waits for it to finish. Other contexts calling nouveau_connector_detect() do require a runtime PM ref, these comprise: status_store() drm sysfs interface ->fill_modes drm callback drm_fb_helper_probe_connector_modes() drm_mode_getconnector() nouveau_connector_hotplug() nouveau_display_hpd_work() nv17_tv_set_property() Stack trace for posterity: INFO: task kworker/0:1:58 blocked for more than 120 seconds.

The ACK/NACK implementation as found in e.g. the G965 has the falling clock edge and the release of the data line after the ACK for the received byte happen at the same time. This is conformant with the I2C specification, which allows a zero hold time, see footnote [3]: "A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the V IH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL." Some HDMI-to-VGA converters apparently fail to adhere to this requirement and latch SDA at the falling clock edge, so instead of an ACK sometimes a NACK is read and the slave (i.e. the EDID ROM) ends the transfer. The bitbanging releases the data line for the ACK only 1/4 bit time after the falling clock edge, so a slave will see the correct value no matter if it samples at the rising or the falling clock edge or in the center. Fallback to bitbanging is already done for the CRT connector.

The issue is that we're not holding the drm lock from when we edit the context images down to when we set the exclusive_stream variable.

The output poll worker meanwhile calls pm_runtime_get_sync() in amdgpu's ->detect hooks, which waits for the ongoing suspend to finish, causing a deadlock. Fix by not acquiring a runtime PM ref if the ->detect hooks are called in the output poll worker's context. This is safe because the poll worker is only enabled while runtime active and we know that ->runtime_suspend waits for it to finish.

Log VBIOS table error. From: Harry Wentland <harry.wentland(a)amd.com> commit caf0a9030d75509f3cacefe466d6d69d26e3dee6 upstream. There have been many reports of Ellesmere and Baffin systems not being able to drive HDMI 4k60 due to the fact that we check the HDMI_6GB_EN bit from VBIOS table. Windows seems to not have this issue. On some systems we fail to the encoder cap info from VBIOS. In that case we should default to enabling HDMI6G support.
