That'll teach me to muck around in this complicated driver. :-) IIUC, the issue is that ifbdev is briefly non-NULL and the if clause happens to be executed when it's non-NULL and it becomes NULL upon or during execution of intel_fbdev_output_poll_changed(), is that correct? Wouldn't the proper solution be to set ifbdev only after configuration was successful, i.e. somewhere at the end of intelfb_create()? With a memory barrier in case intel_fbdev_output_poll_changed is running on a different CPU? > In order to keep the dev_priv->ifbdev alive after failure, we have to > avoid the free and leave it empty until we unload the module. Well, that seems to defeat the goal stated in the commit message of 366e39b4d2c5 to free up the memory if fbdev initialization failed. Not that it's a big deal for me personally, just noting. :-) Thanks, Lukas ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx

[Intel-gfx] [PATCH v7 6/7] efifb: Set info->fbcon_rotate_hint based on drm_get_panel_orientation_quirk
On some hardware the LCD panel is not mounted upright in the casing, but rotated by 90 degrees. In this case we want the console to automatically be rotated to compensate. The drm subsys has a quirk table for this, use the drm_get_panel_orientation_quirk function to get the panel orientation and set info->fbcon_rotate_hint based on this, so that the fbcon console on top of efifb gets automatically rotated to compensate for the panel orientation.

[Intel-gfx] [PATCH v7 0/7] drm/fbdev: Panel orientation connector property support
Here is v7 of my series to add a "panel orientation" property to the drm-connector for the LCD panel to let userspace know about LCD panels which are not mounted upright, as well as detecting upside-down panels without needing quirks (like we do for 90 degree rotated screens). Bartlomiej, can we please have your Acked-by for merging patches 1, 6 and 7 through the drm tree? New in v7: -Fix embarrassing build error in efifb due to me only rebuilding modules after cleanups from v6 New in v6: -Fix / reference kernel-doc comments -Don't export the DRM_MODE_PANEL_ORIENTATION_* defines in the UAPI -Move i915 dsi hardware rotation state read-out to intel_dsi_init() New in v5: -Add kernel-doc comment documenting drm_get_panel_orientation_quirk() -drm_fb_helper: Only use hardware (crtc primary plane) rotation for 180 degrees for now as 9-/270 degrees rotation requires special handling New in v4: -Fix drm_fb_helper code setting an invalid rotation value on the primary plane of disabled/unused crtcs (caught by Fi.CI) New in v3: -As requested by Daniel v3 moves the quirks over from the fbdev subsys to the drm subsys. I've done this by simpy starting with a copy of the quirk table and eventually removing the fbdev version. The 1st patch in this series is a small fbdev/fbcon patch, patches 2-5 are all drm patches and patches 6-7 are fbdev/fbcon patches again. As discussed previously the plan is to merge all 7 patches through the drm tree.

[Intel-gfx] [PATCH v7 1/7] fbcon: Add fbcon_rotate_hint to struct fb_info
On some hardware the LCD panel is not mounted upright in the casing, but upside-down or rotated 90 degrees. In this case we want the console to automatically be rotated to compensate. The fbdev-driver may know about the need to rotate. Add a new fbcon_rotate_hint field to struct fb_info, which gets initialized to -1. If the fbdev-driver knows that some sort of rotation is necessary then it can set this field to a FB_ROTATE_* value to tell the fbcon console driver to rotate the console.

[Intel-gfx] [PATCH v7 5/7] drm/i915: Add "panel orientation" property to the panel connector, v6.
Ideally we could use the VBT for this, that would be simple, in intel_dsi_init() check dev_priv->vbt.dsi.config->rotation, set connector->display_info.panel_orientation accordingly and call drm_connector_init_panel_orientation_property(), done. Unfortunately vbt.dsi.config->rotation is always 0 even on tablets with an upside down LCD and where the GOP is properly rotating the EFI fb in hardware. So instead we end up reading the rotation from the primary plane. This commit only implements the panel orientation property for DSI panels on BYT / CHT hardware, as all known non normal oriented panels sofar are only found on this hardware. Changes in v2: -Read back the rotation applied by the GOP from the primary plane instead of relying on dev_priv->vbt.dsi.config->rotation, because it seems that the VBT rotation filed is always 0 even on devices where the GOP does apply a rotation Changes in v3: -Rewrite the code to read back the orientation from the primary plane to contain all of this in intel_dsi.c instead of poking a bunch of holes between all the different layers Changes in v6: -Move hardware readout to intel_dsi_init() Signed-off-by: Hans de Goede--- drivers/gpu/drm/i915/intel_dsi.c | 28 1 file changed, 28 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_dsi.c b/drivers/gpu/drm/i915/intel_dsi.c index f09474b0c4d3..f67d321376e4 100644 --- a/drivers/gpu/drm/i915/intel_dsi.c +++ b/drivers/gpu/drm/i915/intel_dsi.c @@ -1666,6 +1666,27 @@ static const struct drm_connector_funcs intel_dsi_connector_funcs = { .atomic_duplicate_state = intel_digital_connector_duplicate_state, }; +static int intel_dsi_get_panel_orientation(struct intel_connector *connector) +{ + struct drm_i915_private *dev_priv = to_i915(connector->base.dev); + int orientation = DRM_MODE_PANEL_ORIENTATION_NORMAL; + enum i9xx_plane_id plane; + u32 val; + + if (IS_VALLEYVIEW(dev_priv) || IS_CHERRYVIEW(dev_priv)) { + if (connector->encoder->crtc_mask == BIT(PIPE_B)) + plane = PLANE_B; + else + plane = PLANE_A; + + val = I915_READ(DSPCNTR(plane)); + if (val & DISPPLANE_ROTATE_180) + orientation = DRM_MODE_PANEL_ORIENTATION_BOTTOM_UP; + } + + return orientation; +} + static void intel_dsi_add_properties(struct intel_connector *connector) { struct drm_i915_private *dev_priv = to_i915(connector->base.dev); @@ -1681,6 +1702,13 @@ static void intel_dsi_add_properties(struct intel_connector *connector) allowed_scalers); connector->base.state->scaling_mode = DRM_MODE_SCALE_ASPECT; + + connector->base.display_info.panel_orientation = + intel_dsi_get_panel_orientation(connector); + drm_connector_init_panel_orientation_property( + >base, + connector->panel.fixed_mode->hdisplay, + connector->panel.fixed_mode->vdisplay); } } -- 2.14.3 ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
[Intel-gfx] [PATCH v7 3/7] drm: Add support for a panel-orientation connector property, v6
On some devices the LCD panel is mounted in the casing in such a way that the up/top side of the panel does not match with the top side of the device (e.g. it is mounted upside-down). This commit adds the necessary infra for lcd-panel drm_connector-s to have a "panel orientation" property to communicate how the panel is orientated vs the casing. Userspace can use this property to check for non-normal orientation and then adjust the displayed image accordingly by rotating it to compensate. Changes in v2: -Store panel_orientation in drm_display_info, so that drm_fb_helper.c can access it easily -Have a single drm_connector_init_panel_orientation_property rather then create and attach functions. The caller is expected to set drm_display_info.panel_orientation before calling this, then this will check for platform specific quirks overriding the panel_orientation and if the panel_orientation is set after this then it will attach the property.

[Intel-gfx] [PATCH v7 2/7] drm: Add panel orientation quirks, v6.
Some x86 clamshell design devices use portrait tablet screens and a display engine which cannot rotate in hardware, so the firmware just leaves things as is and we cannot figure out that the display is oriented non upright from the hardware. So at least on x86, we need a quirk table for this. This commit adds a DMI based quirk table which is initially populated with 5 such devices: Asus T100HA, GPD Pocket, GPD win, I.T.Works TW891 and the VIOS LTH17. This quirk table will be used by the drm code to let userspace know that the display is not mounted upright inside the devices case through a new panel orientation drm-connector property, as well as to tell fbcon to rotate the console so that it shows the right way up. Changes in v5: -Add a kernel-doc comment documenting drm_get_panel_orientation_quirk() -Remove board_* matches from the dmi-matches for the VIOS LTH17 laptop, keeping only the (identical) sys_vendor and product_name matches. This is necessary because an older version of the bios has board_vendor set to VOIS instead of VIOS Changes in v6: -Add reference to added kernel-docs in Documentation/gpu/drm-kms-helpers.rst Reviewed-by: Daniel VetterSigned-off-by: Hans de Goede --- Documentation/gpu/drm-kms-helpers.rst | 3 + drivers/gpu/drm/Kconfig| 3 + drivers/gpu/drm/Makefile | 1 + drivers/gpu/drm/drm_panel_orientation_quirks.c | 174 + include/drm/drm_utils.h| 18 +++ 5 files changed, 199 insertions(+) create mode 100644 drivers/gpu/drm/drm_panel_orientation_quirks.c create mode 100644 include/drm/drm_utils.h diff --git a/Documentation/gpu/drm-kms-helpers.rst b/Documentation/gpu/drm-kms-helpers.rst index 13dd237418cc..3ea622876b67 100644 --- a/Documentation/gpu/drm-kms-helpers.rst +++ b/Documentation/gpu/drm-kms-helpers.rst @@ -163,6 +163,9 @@ Panel Helper Reference .. kernel-doc:: drivers/gpu/drm/drm_panel.c :export: +.. kernel-doc:: drivers/gpu/drm/drm_panel_orientation_quirks.c + :export: + Display Port Helper Functions Reference === diff --git a/drivers/gpu/drm/Kconfig b/drivers/gpu/drm/Kconfig index 4d9f21831741..9d005ac98c2b 100644 --- a/drivers/gpu/drm/Kconfig +++ b/drivers/gpu/drm/Kconfig @@ -26,6 +26,9 @@ config DRM_MIPI_DSI bool depends on DRM +config DRM_PANEL_ORIENTATION_QUIRKS + tristate + config DRM_DP_AUX_CHARDEV bool "DRM DP AUX Interface" depends on DRM diff --git a/drivers/gpu/drm/Makefile b/drivers/gpu/drm/Makefile index e9500844333e..e5bf68b9c171 100644 --- a/drivers/gpu/drm/Makefile +++ b/drivers/gpu/drm/Makefile @@ -47,6 +47,7 @@ obj-$(CONFIG_DRM_DEBUG_MM_SELFTEST) += selftests/ obj-$(CONFIG_DRM) += drm.o obj-$(CONFIG_DRM_MIPI_DSI) += drm_mipi_dsi.o +obj-$(CONFIG_DRM_PANEL_ORIENTATION_QUIRKS) += drm_panel_orientation_quirks.o obj-$(CONFIG_DRM_ARM) += arm/ obj-$(CONFIG_DRM_TTM) += ttm/ obj-$(CONFIG_DRM_TDFX) += tdfx/ diff --git a/drivers/gpu/drm/drm_panel_orientation_quirks.c b/drivers/gpu/drm/drm_panel_orientation_quirks.c new file mode 100644 index ..b8765e2ed1d6 --- /dev/null +++ b/drivers/gpu/drm/drm_panel_orientation_quirks.c @@ -0,0 +1,174 @@ +/* + * drm_panel_orientation_quirks.c -- Quirks for non-normal panel orientation + * + * Copyright (C) 2017 Hans de Goede + * + * This file is subject to the terms and conditions of the GNU General Public + * License.

[Intel-gfx] [PATCH v7 4/7] drm/fb-helper: Apply panel orientation connector prop to the primary plane, v6.
Apply the "panel orientation" drm connector prop to the primary plane so that fbcon and fbdev using userspace programs display the right way up.

[Intel-gfx] [PATCH v6 3/7] drm: Add support for a panel-orientation connector property, v6
On some devices the LCD panel is mounted in the casing in such a way that the up/top side of the panel does not match with the top side of the device (e.g. it is mounted upside-down). This commit adds the necessary infra for lcd-panel drm_connector-s to have a "panel orientation" property to communicate how the panel is orientated vs the casing. Userspace can use this property to check for non-normal orientation and then adjust the displayed image accordingly by rotating it to compensate. Changes in v2: -Store panel_orientation in drm_display_info, so that drm_fb_helper.c can access it easily -Have a single drm_connector_init_panel_orientation_property rather then create and attach functions. The caller is expected to set drm_display_info.panel_orientation before calling this, then this will check for platform specific quirks overriding the panel_orientation and if the panel_orientation is set after this then it will attach the property.

[Intel-gfx] [PATCH v6 6/7] efifb: Set info->fbcon_rotate_hint based on drm_get_panel_orientation_quirk
On some hardware the LCD panel is not mounted upright in the casing, but rotated by 90 degrees. In this case we want the console to automatically be rotated to compensate. The drm subsys has a quirk table for this, use the drm_get_panel_orientation_quirk function to get the panel orientation and set info->fbcon_rotate_hint based on this, so that the fbcon console on top of efifb gets automatically rotated to compensate for the panel orientation.

[Intel-gfx] [PATCH v6 1/7] fbcon: Add fbcon_rotate_hint to struct fb_info
On some hardware the LCD panel is not mounted upright in the casing, but upside-down or rotated 90 degrees. In this case we want the console to automatically be rotated to compensate. The fbdev-driver may know about the need to rotate. Add a new fbcon_rotate_hint field to struct fb_info, which gets initialized to -1. If the fbdev-driver knows that some sort of rotation is necessary then it can set this field to a FB_ROTATE_* value to tell the fbcon console driver to rotate the console.

[Intel-gfx] [PATCH v6 5/7] drm/i915: Add "panel orientation" property to the panel connector, v6.
Ideally we could use the VBT for this, that would be simple, in intel_dsi_init() check dev_priv->vbt.dsi.config->rotation, set connector->display_info.panel_orientation accordingly and call drm_connector_init_panel_orientation_property(), done. Unfortunately vbt.dsi.config->rotation is always 0 even on tablets with an upside down LCD and where the GOP is properly rotating the EFI fb in hardware. So instead we end up reading the rotation from the primary plane. This commit only implements the panel orientation property for DSI panels on BYT / CHT hardware, as all known non normal oriented panels sofar are only found on this hardware. Changes in v2: -Read back the rotation applied by the GOP from the primary plane instead of relying on dev_priv->vbt.dsi.config->rotation, because it seems that the VBT rotation filed is always 0 even on devices where the GOP does apply a rotation Changes in v3: -Rewrite the code to read back the orientation from the primary plane to contain all of this in intel_dsi.c instead of poking a bunch of holes between all the different layers Changes in v6: -Move hardware readout to intel_dsi_init() Signed-off-by: Hans de Goede--- drivers/gpu/drm/i915/intel_dsi.c | 28 1 file changed, 28 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_dsi.c b/drivers/gpu/drm/i915/intel_dsi.c index f09474b0c4d3..f67d321376e4 100644 --- a/drivers/gpu/drm/i915/intel_dsi.c +++ b/drivers/gpu/drm/i915/intel_dsi.c @@ -1666,6 +1666,27 @@ static const struct drm_connector_funcs intel_dsi_connector_funcs = { .atomic_duplicate_state = intel_digital_connector_duplicate_state, }; +static int intel_dsi_get_panel_orientation(struct intel_connector *connector) +{ + struct drm_i915_private *dev_priv = to_i915(connector->base.dev); + int orientation = DRM_MODE_PANEL_ORIENTATION_NORMAL; + enum i9xx_plane_id plane; + u32 val; + + if (IS_VALLEYVIEW(dev_priv) || IS_CHERRYVIEW(dev_priv)) { + if (connector->encoder->crtc_mask == BIT(PIPE_B)) + plane = PLANE_B; + else + plane = PLANE_A; + + val = I915_READ(DSPCNTR(plane)); + if (val & DISPPLANE_ROTATE_180) + orientation = DRM_MODE_PANEL_ORIENTATION_BOTTOM_UP; + } + + return orientation; +} + static void intel_dsi_add_properties(struct intel_connector *connector) { struct drm_i915_private *dev_priv = to_i915(connector->base.dev); @@ -1681,6 +1702,13 @@ static void intel_dsi_add_properties(struct intel_connector *connector) allowed_scalers); connector->base.state->scaling_mode = DRM_MODE_SCALE_ASPECT; + + connector->base.display_info.panel_orientation = + intel_dsi_get_panel_orientation(connector); + drm_connector_init_panel_orientation_property( + >base, + connector->panel.fixed_mode->hdisplay, + connector->panel.fixed_mode->vdisplay); } } -- 2.14.3 ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx

[Intel-gfx] [PATCH v6 2/7] drm: Add panel orientation quirks, v6.
Some x86 clamshell design devices use portrait tablet screens and a display engine which cannot rotate in hardware, so the firmware just leaves things as is and we cannot figure out that the display is oriented non upright from the hardware. So at least on x86, we need a quirk table for this. This commit adds a DMI based quirk table which is initially populated with 5 such devices: Asus T100HA, GPD Pocket, GPD win, I.T.Works TW891 and the VIOS LTH17. This quirk table will be used by the drm code to let userspace know that the display is not mounted upright inside the devices case through a new panel orientation drm-connector property, as well as to tell fbcon to rotate the console so that it shows the right way up. Changes in v5: -Add a kernel-doc comment documenting drm_get_panel_orientation_quirk() -Remove board_* matches from the dmi-matches for the VIOS LTH17 laptop, keeping only the (identical) sys_vendor and product_name matches. This is necessary because an older version of the bios has board_vendor set to VOIS instead of VIOS Changes in v6: -Add reference to added kernel-docs in Documentation/gpu/drm-kms-helpers.rst Reviewed-by: Daniel VetterSigned-off-by: Hans de Goede --- Documentation/gpu/drm-kms-helpers.rst | 3 + drivers/gpu/drm/Kconfig| 3 + drivers/gpu/drm/Makefile | 1 + drivers/gpu/drm/drm_panel_orientation_quirks.c | 174 + include/drm/drm_utils.h| 18 +++ 5 files changed, 199 insertions(+) create mode 100644 drivers/gpu/drm/drm_panel_orientation_quirks.c create mode 100644 include/drm/drm_utils.h diff --git a/Documentation/gpu/drm-kms-helpers.rst b/Documentation/gpu/drm-kms-helpers.rst index 13dd237418cc..3ea622876b67 100644 --- a/Documentation/gpu/drm-kms-helpers.rst +++ b/Documentation/gpu/drm-kms-helpers.rst @@ -163,6 +163,9 @@ Panel Helper Reference .. kernel-doc:: drivers/gpu/drm/drm_panel.c :export: +.. kernel-doc:: drivers/gpu/drm/drm_panel_orientation_quirks.c + :export: + Display Port Helper Functions Reference === diff --git a/drivers/gpu/drm/Kconfig b/drivers/gpu/drm/Kconfig index 4d9f21831741..9d005ac98c2b 100644 --- a/drivers/gpu/drm/Kconfig +++ b/drivers/gpu/drm/Kconfig @@ -26,6 +26,9 @@ config DRM_MIPI_DSI bool depends on DRM +config DRM_PANEL_ORIENTATION_QUIRKS + tristate + config DRM_DP_AUX_CHARDEV bool "DRM DP AUX Interface" depends on DRM diff --git a/drivers/gpu/drm/Makefile b/drivers/gpu/drm/Makefile index e9500844333e..e5bf68b9c171 100644 --- a/drivers/gpu/drm/Makefile +++ b/drivers/gpu/drm/Makefile @@ -47,6 +47,7 @@ obj-$(CONFIG_DRM_DEBUG_MM_SELFTEST) += selftests/ obj-$(CONFIG_DRM) += drm.o obj-$(CONFIG_DRM_MIPI_DSI) += drm_mipi_dsi.o +obj-$(CONFIG_DRM_PANEL_ORIENTATION_QUIRKS) += drm_panel_orientation_quirks.o obj-$(CONFIG_DRM_ARM) += arm/ obj-$(CONFIG_DRM_TTM) += ttm/ obj-$(CONFIG_DRM_TDFX) += tdfx/ diff --git a/drivers/gpu/drm/drm_panel_orientation_quirks.c b/drivers/gpu/drm/drm_panel_orientation_quirks.c new file mode 100644 index ..b8765e2ed1d6 --- /dev/null +++ b/drivers/gpu/drm/drm_panel_orientation_quirks.c @@ -0,0 +1,174 @@ +/* + * drm_panel_orientation_quirks.c -- Quirks for non-normal panel orientation + * + * Copyright (C) 2017 Hans de Goede + * + * This file is subject to the terms and conditions of the GNU General Public + * License.

[Intel-gfx] [PATCH v6 0/7] drm/fbdev: Panel orientation connector property support
Hi All, Here is v6 of my series to add a "panel orientation" property to the drm-connector for the LCD panel to let userspace know about LCD panels which are not mounted upright, as well as detecting upside-down panels without needing quirks (like we do for 90 degree rotated screens). Bartlomiej, can we please have your Acked-by for merging patches 1, 6 and 7 through the drm tree? New in v6: -Fix / reference kernel-doc comments -Don't export the DRM_MODE_PANEL_ORIENTATION_* defines in the UAPI -Move i915 dsi hardware rotation state read-out to intel_dsi_init() New in v5: -Add kernel-doc comment documenting drm_get_panel_orientation_quirk() -drm_fb_helper: Only use hardware (crtc primary plane) rotation for 180 degrees for now as 9-/270 degrees rotation requires special handling New in v4: -Fix drm_fb_helper code setting an invalid rotation value on the primary plane of disabled/unused crtcs (caught by Fi.CI) New in v3: -As requested by Daniel v3 moves the quirks over from the fbdev subsys to the drm subsys. I've done this by simpy starting with a copy of the quirk table and eventually removing the fbdev version. The 1st patch in this series is a small fbdev/fbcon patch, patches 2-5 are all drm patches and patches 6-7 are fbdev/fbcon patches again. As discussed previously the plan is to merge all 7 patches through the drm tree.

[Intel-gfx] [PATCH v6 3/7] drm: Add support for a panel-orientation connector property, v6
On some devices the LCD panel is mounted in the casing in such a way that the up/top side of the panel does not match with the top side of the device (e.g. it is mounted upside-down). This commit adds the necessary infra for lcd-panel drm_connector-s to have a "panel orientation" property to communicate how the panel is orientated vs the casing. Userspace can use this property to check for non-normal orientation and then adjust the displayed image accordingly by rotating it to compensate. Changes in v2: -Store panel_orientation in drm_display_info, so that drm_fb_helper.c can access it easily -Have a single drm_connector_init_panel_orientation_property rather then create and attach functions. The caller is expected to set drm_display_info.panel_orientation before calling this, then this will check for platform specific quirks overriding the panel_orientation and if the panel_orientation is set after this then it will attach the property.

[Intel-gfx] [PATCH v6 2/7] drm: Add panel orientation quirks, v6.
Some x86 clamshell design devices use portrait tablet screens and a display engine which cannot rotate in hardware, so the firmware just leaves things as is and we cannot figure out that the display is oriented non upright from the hardware. So at least on x86, we need a quirk table for this. This commit adds a DMI based quirk table which is initially populated with 5 such devices: Asus T100HA, GPD Pocket, GPD win, I.T.Works TW891 and the VIOS LTH17. This quirk table will be used by the drm code to let userspace know that the display is not mounted upright inside the devices case through a new panel orientation drm-connector property, as well as to tell fbcon to rotate the console so that it shows the right way up. Changes in v5: -Add a kernel-doc comment documenting drm_get_panel_orientation_quirk() -Remove board_* matches from the dmi-matches for the VIOS LTH17 laptop, keeping only the (identical) sys_vendor and product_name matches. This is necessary because an older version of the bios has board_vendor set to VOIS instead of VIOS Changes in v6: -Add reference to added kernel-docs in Documentation/gpu/drm-kms-helpers.rst Reviewed-by: Daniel VetterSigned-off-by: Hans de Goede --- Documentation/gpu/drm-kms-helpers.rst | 3 + drivers/gpu/drm/Kconfig| 3 + drivers/gpu/drm/Makefile | 1 + drivers/gpu/drm/drm_panel_orientation_quirks.c | 174 + include/drm/drm_utils.h| 18 +++ 5 files changed, 199 insertions(+) create mode 100644 drivers/gpu/drm/drm_panel_orientation_quirks.c create mode 100644 include/drm/drm_utils.h diff --git a/Documentation/gpu/drm-kms-helpers.rst b/Documentation/gpu/drm-kms-helpers.rst index 13dd237418cc..3ea622876b67 100644 --- a/Documentation/gpu/drm-kms-helpers.rst +++ b/Documentation/gpu/drm-kms-helpers.rst @@ -163,6 +163,9 @@ Panel Helper Reference .. kernel-doc:: drivers/gpu/drm/drm_panel.c :export: +.. kernel-doc:: drivers/gpu/drm/drm_panel_orientation_quirks.c + :export: + Display Port Helper Functions Reference === diff --git a/drivers/gpu/drm/Kconfig b/drivers/gpu/drm/Kconfig index 4d9f21831741..9d005ac98c2b 100644 --- a/drivers/gpu/drm/Kconfig +++ b/drivers/gpu/drm/Kconfig @@ -26,6 +26,9 @@ config DRM_MIPI_DSI bool depends on DRM +config DRM_PANEL_ORIENTATION_QUIRKS + tristate + config DRM_DP_AUX_CHARDEV bool "DRM DP AUX Interface" depends on DRM diff --git a/drivers/gpu/drm/Makefile b/drivers/gpu/drm/Makefile index e9500844333e..e5bf68b9c171 100644 --- a/drivers/gpu/drm/Makefile +++ b/drivers/gpu/drm/Makefile @@ -47,6 +47,7 @@ obj-$(CONFIG_DRM_DEBUG_MM_SELFTEST) += selftests/ obj-$(CONFIG_DRM) += drm.o obj-$(CONFIG_DRM_MIPI_DSI) += drm_mipi_dsi.o +obj-$(CONFIG_DRM_PANEL_ORIENTATION_QUIRKS) += drm_panel_orientation_quirks.o obj-$(CONFIG_DRM_ARM) += arm/ obj-$(CONFIG_DRM_TTM) += ttm/ obj-$(CONFIG_DRM_TDFX) += tdfx/ diff --git a/drivers/gpu/drm/drm_panel_orientation_quirks.c b/drivers/gpu/drm/drm_panel_orientation_quirks.c new file mode 100644 index ..b8765e2ed1d6 --- /dev/null +++ b/drivers/gpu/drm/drm_panel_orientation_quirks.c @@ -0,0 +1,174 @@ +/* + * drm_panel_orientation_quirks.c -- Quirks for non-normal panel orientation + * + * Copyright (C) 2017 Hans de Goede + * + * This file is subject to the terms and conditions of the GNU General Public + * License.

[Intel-gfx] [PATCH v6 0/7] drm/fbdev: Panel orientation connector property support
Hi All, Here is v6 of my series to add a "panel orientation" property to the drm-connector for the LCD panel to let userspace know about LCD panels which are not mounted upright, as well as detecting upside-down panels without needing quirks (like we do for 90 degree rotated screens). Bartlomiej, can we please have your Acked-by for merging patches 1, 6 and 7 through the drm tree? New in v6: -Fix / reference kernel-doc comments -Don't export the DRM_MODE_PANEL_ORIENTATION_* defines in the UAPI -Move i915 dsi hardware rotation state read-out to intel_dsi_init() New in v5: -Add kernel-doc comment documenting drm_get_panel_orientation_quirk() -drm_fb_helper: Only use hardware (crtc primary plane) rotation for 180 degrees for now as 9-/270 degrees rotation requires special handling New in v4: -Fix drm_fb_helper code setting an invalid rotation value on the primary plane of disabled/unused crtcs (caught by Fi.CI) New in v3: -As requested by Daniel v3 moves the quirks over from the fbdev subsys to the drm subsys. I've done this by simpy starting with a copy of the quirk table and eventually removing the fbdev version. The 1st patch in this series is a small fbdev/fbcon patch, patches 2-5 are all drm patches and patches 6-7 are fbdev/fbcon patches again. As discussed previously the plan is to merge all 7 patches through the drm tree.

[Intel-gfx] [PATCH v6 5/7] drm/i915: Add "panel orientation" property to the panel connector, v6.
Ideally we could use the VBT for this, that would be simple, in intel_dsi_init() check dev_priv->vbt.dsi.config->rotation, set connector->display_info.panel_orientation accordingly and call drm_connector_init_panel_orientation_property(), done. Unfortunately vbt.dsi.config->rotation is always 0 even on tablets with an upside down LCD and where the GOP is properly rotating the EFI fb in hardware. So instead we end up reading the rotation from the primary plane. This commit only implements the panel orientation property for DSI panels on BYT / CHT hardware, as all known non normal oriented panels sofar are only found on this hardware. Changes in v2: -Read back the rotation applied by the GOP from the primary plane instead of relying on dev_priv->vbt.dsi.config->rotation, because it seems that the VBT rotation filed is always 0 even on devices where the GOP does apply a rotation Changes in v3: -Rewrite the code to read back the orientation from the primary plane to contain all of this in intel_dsi.c instead of poking a bunch of holes between all the different layers Changes in v6: -Move hardware readout to intel_dsi_init() Signed-off-by: Hans de Goede--- drivers/gpu/drm/i915/intel_dsi.c | 28 1 file changed, 28 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_dsi.c b/drivers/gpu/drm/i915/intel_dsi.c index f09474b0c4d3..f67d321376e4 100644 --- a/drivers/gpu/drm/i915/intel_dsi.c +++ b/drivers/gpu/drm/i915/intel_dsi.c @@ -1666,6 +1666,27 @@ static const struct drm_connector_funcs intel_dsi_connector_funcs = { .atomic_duplicate_state = intel_digital_connector_duplicate_state, }; +static int intel_dsi_get_panel_orientation(struct intel_connector *connector) +{ + struct drm_i915_private *dev_priv = to_i915(connector->base.dev); + int orientation = DRM_MODE_PANEL_ORIENTATION_NORMAL; + enum i9xx_plane_id plane; + u32 val; + + if (IS_VALLEYVIEW(dev_priv) || IS_CHERRYVIEW(dev_priv)) { + if (connector->encoder->crtc_mask == BIT(PIPE_B)) + plane = PLANE_B; + else + plane = PLANE_A; + + val = I915_READ(DSPCNTR(plane)); + if (val & DISPPLANE_ROTATE_180) + orientation = DRM_MODE_PANEL_ORIENTATION_BOTTOM_UP; + } + + return orientation; +} + static void intel_dsi_add_properties(struct intel_connector *connector) { struct drm_i915_private *dev_priv = to_i915(connector->base.dev); @@ -1681,6 +1702,13 @@ static void intel_dsi_add_properties(struct intel_connector *connector) allowed_scalers); connector->base.state->scaling_mode = DRM_MODE_SCALE_ASPECT; + + connector->base.display_info.panel_orientation = + intel_dsi_get_panel_orientation(connector); + drm_connector_init_panel_orientation_property( + >base, + connector->panel.fixed_mode->hdisplay, + connector->panel.fixed_mode->vdisplay); } } -- 2.14.3 ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx

On some hardware the LCD panel is not mounted upright in the casing, but upside-down or rotated 90 degrees. In this case we want the console to automatically be rotated to compensate. The fbdev-driver may know about the need to rotate. Add a new fbcon_rotate_hint field to struct fb_info, which gets initialized to -1. If the fbdev-driver knows that some sort of rotation is necessary then it can set this field to a FB_ROTATE_* value to tell the fbcon console driver to rotate the console.

Re: [Intel-gfx] [PATCH v5 5/7] drm/i915: Add "panel orientation" property to the panel connector
Hi, On 11/06/2017 11:17 AM, Daniel Vetter wrote: On Sat, Nov 04, 2017 at 03:08:26PM +0100, Hans de Goede wrote: Ideally we could use the VBT for this, that would be simple, in intel_dsi_init() check dev_priv->vbt.dsi.config->rotation, set connector->display_info.panel_orientation accordingly and call drm_connector_init_panel_orientation_property(), done. Unfortunately vbt.dsi.config->rotation is always 0 even on tablets with an upside down LCD and where the GOP is properly rotating the EFI fb in hardware. So instead we end up reading the rotation from the primary plane. To read the info from the primary plane, we need to know which crtc the panel is hooked up to, so we do this the first time the panel encoder's get_config function get called, as by then the encoder crtc routing has been set up. This commit only implements the panel orientation property for DSI panels on BYT / CHT / BXT hardware, as all known non normal oriented panels are only found on this hardware.
