Print out the HW context object information per ring. Even though the existing code only utilizes the render ring, it's simple enough to support future expansion. I had this in a patch somewhere in a rev of the original implementation, but I must have lost it. Signed-off-by:

The bit controlling whether PIPE_CONTROL DW/QW write targets the global GTT or PPGTT moved moved from DW 2 bit 2 to DW 1 bit 24 on IVB. I verified on IVB that the fix is in fact effective. Without the fix none of the scratch writes actually landed in the pipe control page.

The FDI link has supported link reversal to make the PCB layout engineer's life easier for quite a while and we have always presered this bit as we programmed FDI_RX_CTL with a read/modify/write sequence. We're trying to take a bit more control over what the BIOS leaves in various register and with the introduction of DDI, started to program FDI_RX_CTL fully. There's a fused bit to indicate DMI link reversal and FDI defaults to mirroring that configuration. We have a bit to override that behaviour that we need to preserve from the BIOS. Signed-off-by:

Support for real RGB332 is a rarity, most hardware only really support C8. So use C8 instead of RGB332 when determining the format based on depth/bpp. This fixes 8bpp fbcon on i915, since i915 will only accept C8 and not RGB332.

As explained by Chris Wilson gem objects in stolen memory are always coherent with the GPU so we don't need to ever flush the CPU caches for these. This fixes a breakage - at least with the compact sg patches applied - during the resume/restore gtt mappings path, when we tried to clflush an FB object in stolen memory, but since stolen objects don't have backing pages we passed an invalid page pointer to drm_clflush_page().

If a GPU reset occurs while a page flip has been submitted to the ring, the flip will never complete once the ring has been reset.

With the previous patch "drm/i915: disable shared panel fitter for pipe" we now disable the panel fitter at the right spot in the modeset sequence in the crtc functions on all platforms. Hence the disabling in intel_disable_lvds is no longer required and potentially harmful (since the plane is still enabled at this point). Similarly on the enabling side we enable the panel fitter in the lvds callback only once the plane is enabled. Which is too late. Hence move this into a new intel_pre_enable_lvds callback. Finally we can ditch lvds_encoder->pfit_dirty - this was required to work around the crtc helper semantics, but with the new i915 modeset infrastructure we should enable/disable the pfit only when enabling or disabling the entire output pipeline. So separate state tracking for the pfit is no longer required. Signed-off-by:

Some early bios versions seem to ship with the wrong tuning values for the MCH, possible resulting in pipe underruns under load. Especially on DP outputs this can lead to black screen, since DP really doesn't like an occasional whack from an underrun. Unfortunately the registers seem to be locked after boot, so the only thing we can do is politely point out issues and suggest a BIOS upgrade. Arthur Runyan pointed us at this issue while discussion DP bugs - thus far no confirmation from a bug report yet that it helps. But at least some of my machines here have wrong values, so this might be useful in understanding bug reports. v2: After a bit more discussion with Art and Ben we've decided to only the check the watermark values, since the OREF ones could be be a notch more aggressive on certain machines.

Turns out that the original sequence was the right thing to do for a different set of machines. Worse, setting the backlight level _after_ enabling it seems to reset it somehow. So we need to make that one conditional upon the backlight having been reset to zero, and add the old one back. Cargo-culting at it's best, but it seems to work.

i915 driver needs to do modeset when 1. system resumes from sleep 2. lid is opened In PM_SUSPEND_MEM state, all the GPEs are cleared when system resumes, thus it is the i915_resume code does the modeset rather than intel_lid_notify(). But in PM_SUSPEND_FREEZE state, this will be broken because system is still responsive to the lid events. 1. When we close the lid in Freeze state, intel_lid_notify() sets modeset_on_lid. 2. When we reopen the lid, intel_lid_notify() will do a modeset, before the system is resumed. here is the error log, [92146.548074] WARNING: at drivers/gpu/drm/i915/intel_display.c:1028 intel_wait_for_pipe_off+0x184/0x190 [i915]() [92146.548076] Hardware name: VGN-Z540N [92146.548078] pipe_off wait timed out [92146.548167] Modules linked in: hid_generic usbhid hid snd_hda_codec_realtek snd_hda_intel snd_hda_codec parport_pc snd_hwdep ppdev snd_pcm_oss i915 snd_mixer_oss snd_pcm arc4 iwldvm snd_seq_dummy mac80211 snd_seq_oss snd_seq_midi fbcon tileblit font bitblit softcursor drm_kms_helper snd_rawmidi snd_seq_midi_event coretemp drm snd_seq kvm btusb bluetooth snd_timer iwlwifi pcmcia tpm_infineon i2c_algo_bit joydev snd_seq_device intel_agp cfg80211 snd intel_gtt yenta_socket pcmcia_rsrc sony_laptop agpgart microcode psmouse tpm_tis serio_raw mxm_wmi soundcore snd_page_alloc tpm acpi_cpufreq lpc_ich pcmcia_core tpm_bios mperf processor lp parport firewire_ohci firewire_core crc_itu_t sdhci_pci sdhci thermal e1000e [92146.548173] Pid: 4304, comm: kworker/0:0 Tainted: G W 3.8.0-rc3-s0i3-v3-test+ #9 [92146.548175] Call Trace: [92146.548189] [<c10378e2>] warn_slowpath_common+0x72/0xa0 [92146.548227] [<f86398b4>] ? intel_wait_for_pipe_off+0x184/0x190 [i915] [92146.548263] [<f86398b4>] ? intel_wait_for_pipe_off+0x184/0x190 [i915] [92146.548270] [<c10379b3>] warn_slowpath_fmt+0x33/0x40 [92146.548307] [<f86398b4>] intel_wait_for_pipe_off+0x184/0x190 [i915] [92146.548344] [<f86399c2>] intel_disable_pipe+0x102/0x190 [i915] [92146.548380] [<f8639ea4>] ? intel_disable_plane+0x64/0x80 [i915] [92146.548417] [<f8639f7c>] i9xx_crtc_disable+0xbc/0x150 [i915] [92146.548456] [<f863ebee>] intel_crtc_update_dpms+0x5e/0x90 [i915] [92146.548493] [<f86437cf>] intel_modeset_setup_hw_state+0x42f/0x8f0 [i915] [92146.548535] [<f8645b0b>] intel_lid_notify+0x9b/0xc0 [i915] [92146.548543] [<c15610d3>] notifier_call_chain+0x43/0x60 [92146.548550] [<c105d1e1>] __blocking_notifier_call_chain+0x41/0x80 [92146.548556] [<c105d23f>] blocking_notifier_call_chain+0x1f/0x30 [92146.548563] [<c131a684>] acpi_lid_send_state+0x78/0xa4 [92146.548569] [<c131aa9e>] acpi_button_notify+0x3b/0xf1 [92146.548577] [<c12df56a>] ? acpi_os_execute+0x17/0x19 [92146.548582] [<c12e591a>] ? acpi_ec_sync_query+0xa5/0xbc [92146.548589] [<c12e2b82>] acpi_device_notify+0x16/0x18 [92146.548595] [<c12f4904>] acpi_ev_notify_dispatch+0x38/0x4f [92146.548600] [<c12df0e8>] acpi_os_execute_deferred+0x20/0x2b [92146.548607] [<c1051208>] process_one_work+0x128/0x3f0 [92146.548613] [<c1564f73>] ? common_interrupt+0x33/0x38 [92146.548618] [<c104f8c0>] ? wake_up_worker+0x30/0x30 [92146.548624] [<c12df0c8>] ? acpi_os_wait_events_complete+0x1e/0x1e [92146.548629] [<c10524f9>] worker_thread+0x119/0x3b0 [92146.548634] [<c10523e0>] ? manage_workers+0x240/0x240 [92146.548640] [<c1056e84>] kthread+0x94/0xa0 [92146.548647] [<c1060000>] ? ftrace_raw_output_sched_stat_runtime+0x70/0xf0 [92146.548652] [<c15649b7>] ret_from_kernel_thread+0x1b/0x28 [92146.548658] [<c1056df0>] ? kthread_create_on_node+0xc0/0xc0 three different modeset flags are introduced in this patch MODESET_ON_LID_OPEN: do modeset on next lid open event MODESET_DONE: modeset already done MODESET_SUSPENDED: suspended, only do modeset when system is resumed In this way, 1. when lid is closed, MODESET_ON_LID_OPEN is set so that we'll do modeset on next lid open event. 2. when lid is opened, MODESET_DONE is set so that duplicate lid open events will be ignored. 3. when system suspends, MODESET_SUSPENDED is set.

The RC6 VIDS has a linear ramp starting at 250mv, which means any values below 250 are invalid. The old buggy macros tried to adjust for this to be more flexible, but there is no need. As Dan pointed out the ENCODE only ever has one value. The only invalid value for decode is an input of 0 which means something is really wonky, and the cases where DECODE are used either don't matter (debug values), or would be implicitly correct (the check for less than 450). This patch makes simpler, easier to read macros which are actually correct. Maybe this patch can actually fix some bugs now.

For devices that conform to PCIe r3.0 and have a Link Capabilities 2 register, we test and report every bit in the Supported Link Speeds Vector field. For a device that supports both 2.5GT/s and 5.0GT/s, we set both DRM_PCIE_SPEED_25 and DRM_PCIE_SPEED_50 in the returned mask. For pre-r3.0 devices, the Link Capabilities 0010b encoding (PCI_EXP_LNKCAP_SLS_5_0GB) means that both 5.0GT/s and 2.5GT/s are supported, so set both DRM_PCIE_SPEED_25 and DRM_PCIE_SPEED_50 in this case as well.

Instead of reimplementing all of the dma_buf functionality in every driver, create helpers drm_prime_import and drm_prime_export that implement them in terms of new, lower-level hook functions: gem_prime_pin: callback when a buffer is created, used to pin buffers into GTT gem_prime_get_sg_table: convert a drm_gem_object to an sg_table for export gem_prime_import_sg_table: convert an sg_table into a drm_gem_object gem_prime_vmap, gem_prime_vunmap: map and unmap an object These hooks are optional; drivers can opt in by using drm_gem_prime_import and drm_gem_prime_export as the .gem_prime_import and .gem_prime_export fields of struct drm_driver. v2: - Drop .begin_cpu_access. None of the drivers this code replaces implemented it. Having it here was a leftover from when I was trying to include i915 in this rework. - Use mutex_lock instead of mutex_lock_interruptible, as these three drivers did. This patch series shouldn't change that behavior. - Rename helpers to gem_prime_get_sg_table and gem_prime_import_sg_table. Rename struct sg_table* variables to 'sgt' for clarity. - Update drm.tmpl for these new hooks. v3: - Pass the vaddr down to the driver. This lets drivers that just call vunmap on the pointer avoid having to store the pointer in their GEM private structures. - Move documentation into a /** DOC */ comment in drm_prime.c and include it in drm.tmpl with a !P line. I tried to use !F lines to include documentation of the individual functions from drmP.h, but the docproc / kernel-doc scripts barf on that file, so hopefully this is good enough for now. - apply refcount fix from commit be8a42ae ("drm/prime: drop reference on imported dma-buf come from gem") Signed-off-by:
