X-BeenThere: intel-gfx@lists.freedesktop.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Intel graphics driver community testing & development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Paulo Zanoni , Rodrigo Vivi MIME-Version: 1.0 Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" X-Virus-Scanned: ClamAV using ClamSMTP From: Manasi Navare These tables are used on voltage vswing sequence initialization on Icelake. The swing_sel on the spec's table is defined in a 4 bits binary like 1010. However the register bits are split in upper 1 bit swing_sel and lower 3 bits swing sel. In this table here we store this value as a single value in hex like it is mentioned in the Bspec and split it to the upper and lower bit values only while programming the registers. For instance: b1010 is written as 0xA and then while writing to the register, the upper 1 bit is obtained by (0xA & 0x8) and shifting by appropriate bits while lower 3 bits are obtained by (0xA & 0x7) and shifting by appropriate bits. Some of the columns need to be updated after the spec is updated. v5 (from Paulo): * Checkpatch fixes. v4 (from Paulo): * Fix minor typo * Coding style conformance v3: * Get rid of HDMI/DVI tables, same as DP (Paulo) * Use combo_phy in ddi buf trans table defs (Paulo) v2: * Added DW4_scaling_hex column to the translation tables (Rodrigo) Cc: Jani Nikula Cc: Rodrigo Vivi Reviewed-by: Paulo Zanoni Signed-off-by: Manasi Navare Signed-off-by: Paulo Zanoni --- drivers/gpu/drm/i915/intel_ddi.c | 99 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 99 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_ddi.c b/drivers/gpu/drm/i915/intel_ddi.c index 81383e3dc91f..0a4683991ec2 100644 --- a/drivers/gpu/drm/i915/intel_ddi.c +++ b/drivers/gpu/drm/i915/intel_ddi.c @@ -492,6 +492,105 @@ static const struct cnl_ddi_buf_trans cnl_ddi_translations_edp_1_05V[] = { { 0x2, 0x7F, 0x3F, 0x00, 0x00 }, /* 400 400 0.0 */ }; +struct icl_combo_phy_ddi_buf_trans { + u32 dw2_swing_select; + u32 dw2_swing_scalar; + u32 dw4_scaling; +}; + +/* Voltage Swing Programming for VccIO 0.85V for DP */ +static const struct icl_combo_phy_ddi_buf_trans icl_combo_phy_ddi_translations_dp_hdmi_0_85V[] = { + /* Voltage mV db */ + { 0x2, 0x98, 0x0018 }, /* 400 0.0 */ + { 0x2, 0x98, 0x3015 }, /* 400 3.5 */ + { 0x2, 0x98, 0x6012 }, /* 400 6.0 */ + { 0x2, 0x98, 0x900F }, /* 400 9.5 */ + { 0xB, 0x70, 0x0018 }, /* 600 0.0 */ + { 0xB, 0x70, 0x3015 }, /* 600 3.5 */ + { 0xB, 0x70, 0x6012 }, /* 600 6.0 */ + { 0x5, 0x00, 0x0018 }, /* 800 0.0 */ + { 0x5, 0x00, 0x3015 }, /* 800 3.5 */ + { 0x6, 0x98, 0x0018 }, /* 1200 0.0 */ +}; + +/* FIXME - After table is updated in Bspec */ +/* Voltage Swing Programming for VccIO 0.85V for eDP */ +static const struct icl_combo_phy_ddi_buf_trans icl_combo_phy_ddi_translations_edp_0_85V[] = { + /* Voltage mV db */ + { 0x0, 0x00, 0x00 }, /* 200 0.0 */ + { 0x0, 0x00, 0x00 }, /* 200 1.5 */ + { 0x0, 0x00, 0x00 }, /* 200 4.0 */ + { 0x0, 0x00, 0x00 }, /* 200 6.0 */ + { 0x0, 0x00, 0x00 }, /* 250 0.0 */ + { 0x0, 0x00, 0x00 }, /* 250 1.5 */ + { 0x0, 0x00, 0x00 }, /* 250 4.0 */ + { 0x0, 0x00, 0x00 }, /* 300 0.0 */ + { 0x0, 0x00, 0x00 }, /* 300 1.5 */ + { 0x0, 0x00, 0x00 }, /* 350 0.0 */ +}; + +/* Voltage Swing Programming for VccIO 0.95V for DP */ +static const struct icl_combo_phy_ddi_buf_trans icl_combo_phy_ddi_translations_dp_hdmi_0_95V[] = { + /* Voltage mV db */ + { 0x2, 0x98, 0x0018 }, /* 400 0.0 */ + { 0x2, 0x98, 0x3015 }, /* 400 3.5 */ + { 0x2, 0x98, 0x6012 }, /* 400 6.0 */ + { 0x2, 0x98, 0x900F }, /* 400 9.5 */ + { 0x4, 0x98, 0x0018 }, /* 600 0.0 */ + { 0x4, 0x98, 0x3015 }, /* 600 3.5 */ + { 0x4, 0x98, 0x6012 }, /* 600 6.0 */ + { 0x5, 0x76, 0x0018 }, /* 800 0.0 */ + { 0x5, 0x76, 0x3015 }, /* 800 3.5 */ + { 0x6, 0x98, 0x0018 }, /* 1200 0.0 */ +}; + +/* FIXME - After table is updated in Bspec */ +/* Voltage Swing Programming for VccIO 0.95V for eDP */ +static const struct icl_combo_phy_ddi_buf_trans icl_combo_phy_ddi_translations_edp_0_95V[] = { + /* Voltage mV db */ + { 0x0, 0x00, 0x00 }, /* 200 0.0 */ + { 0x0, 0x00, 0x00 }, /* 200 1.5 */ + { 0x0, 0x00, 0x00 }, /* 200 4.0 */ + { 0x0, 0x00, 0x00 }, /* 200 6.0 */ + { 0x0, 0x00, 0x00 }, /* 250 0.0 */ + { 0x0, 0x00, 0x00 }, /* 250 1.5 */ + { 0x0, 0x00, 0x00 }, /* 250 4.0 */ + { 0x0, 0x00, 0x00 }, /* 300 0.0 */ + { 0x0, 0x00, 0x00 }, /* 300 1.5 */ + { 0x0, 0x00, 0x00 }, /* 350 0.0 */ +}; + +/* Voltage Swing Programming for VccIO 1.05V for DP */ +static const struct icl_combo_phy_ddi_buf_trans icl_combo_phy_ddi_translations_dp_hdmi_1_05V[] = { + /* Voltage mV db */ + { 0x2, 0x98, 0x0018 }, /* 400 0.0 */ + { 0x2, 0x98, 0x3015 }, /* 400 3.5 */ + { 0x2, 0x98, 0x6012 }, /* 400 6.0 */ + { 0x2, 0x98, 0x900F }, /* 400 9.5 */ + { 0x4, 0x98, 0x0018 }, /* 600 0.0 */ + { 0x4, 0x98, 0x3015 }, /* 600 3.5 */ + { 0x4, 0x98, 0x6012 }, /* 600 6.0 */ + { 0x5, 0x71, 0x0018 }, /* 800 0.0 */ + { 0x5, 0x71, 0x3015 }, /* 800 3.5 */ + { 0x6, 0x98, 0x0018 }, /* 1200 0.0 */ +}; + +/* FIXME - After table is updated in Bspec */ +/* Voltage Swing Programming for VccIO 1.05V for eDP */ +static const struct icl_combo_phy_ddi_buf_trans icl_combo_phy_ddi_translations_edp_1_05V[] = { + /* Voltage mV db */ + { 0x0, 0x00, 0x00 }, /* 200 0.0 */ + { 0x0, 0x00, 0x00 }, /* 200 1.5 */ + { 0x0, 0x00, 0x00 }, /* 200 4.0 */ + { 0x0, 0x00, 0x00 }, /* 200 6.0 */ + { 0x0, 0x00, 0x00 }, /* 250 0.0 */ + { 0x0, 0x00, 0x00 }, /* 250 1.5 */ + { 0x0, 0x00, 0x00 }, /* 250 4.0 */ + { 0x0, 0x00, 0x00 }, /* 300 0.0 */ + { 0x0, 0x00, 0x00 }, /* 300 1.5 */ + { 0x0, 0x00, 0x00 }, /* 350 0.0 */ +}; + static const struct ddi_buf_trans * bdw_get_buf_trans_edp(struct drm_i915_private *dev_priv, int *n_entries) {
