2020-09-07drm/i915/selftests: Mock the status_page.vma for the kernel_contextChris Wilson

2020-09-07drm/i915: Reduce i915_request.lock contention for i915_request_waitChris Wilson
Currently, we use i915_request_completed() directly in i915_request_wait() and follow up with a manual invocation of dma_fence_signal(). This appears to cause a large number of contentions on i915_request.lock as when the process is woken up after the fence is signaled by an interrupt, we will then try and call dma_fence_signal() ourselves while the signaler is still holding the lock. dma_fence_is_signaled() has the benefit of checking the DMA_FENCE_FLAG_SIGNALED_BIT prior to calling dma_fence_signal() and so avoids most of that contention.

2020-08-19drm/i915/selftests: Avoid passing a random 0 into ilog2George Spelvin
igt_mm_config() calls ilog2() on the (pseudo)random 21-bit number s>>12. Once in 2 million seeds, this is zero and ilog2 summons the nasal demons. There was an attempt to handle this case with a max(), but that's too late; ms could already be something bizarre. Given that the low 12 bits of s and ms are always zero, it's a lot simpler just to divide them by 4096, then everything fits into 32 bits, and we can easily generate a random number 1 <= s <= 0x1fffff.

2020-08-17drm/i915: Initial implementation of PSR2 selective fetchJosé Roberto de Souza
All GEN12 platforms supports PSR2 selective fetch but not all GEN12 platforms supports PSR2 hardware tracking(aka RKL). This feature consists in software programming registers with the damaged area of each plane this way hardware will only fetch from memory those areas and sent the PSR2 selective update blocks to panel, saving even more power. But as initial step it is only enabling the full frame fetch at every flip, the actual selective fetch part will come in a future patch. Also this is only handling the page flip side, it is still completely missing frontbuffer modifications, that is why the enable_psr2_sel_fetch parameter was added. v3: - calling intel_psr2_sel_fetch_update() during the atomic check phase (Ville) BSpec: 55229 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Imre Deak <imre.deak@intel.com> Cc: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Reviewed-by: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200810174144.76761-1-jose.souza@intel.com Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
2020-08-17drm/i915/kbl: Fix revision ID checksMatt Roper
We usually assume that increasing PCI device revision ID's translates to newer steppings; macros like IS_KBL_REVID() that we use rely on this behavior. Unfortunately this turns out to not be true on KBL; the newer device 2 revision ID's sometimes go backward to older steppings. The situation is further complicated by different GT and display steppings associated with each revision ID. Let's work around this by providing a table to map the revision ID to specific GT and display steppings, and then perform our comparisons on the mapped values. v2: - Move the kbl_revids[] array to intel_workarounds.c to avoid compiler warnings about an unused variable in files that don't call the macros (kernel test robot).

The command register is the PCODE MBOX low register not the high one as described by the spec. This left the system with the TC-cold power state being blocked all the time. Fix things by using the correct register. Also to make sure we retry a request for at least 600usec, when the PCODE MBOX command itself succeeded, but the TC-cold block command failed, sleep for 1msec unconditionally after any fail. The change was tested with JTAG register read of the HW/FW's actual TC-cold state, which reported the expected states after this change.

2020-08-17drm/i915/selftests: Avoid passing a random 0 into ilog2George Spelvin
igt_mm_config() calls ilog2() on the (pseudo)random 21-bit number s>>12. Once in 2 million seeds, this is zero and ilog2 summons the nasal demons. There was an attempt to handle this case with a max(), but that's too late; ms could already be something bizarre. Given that the low 12 bits of s and ms are always zero, it's a lot simpler just to divide them by 4096, then everything fits into 32 bits, and we can easily generate a random number 1 <= s <= 0x1fffff.

2020-08-17drm/i915/rkl: Add DPLL4 supportMatt Roper
Rocket Lake has a third DPLL (called 'DPLL4') that must be used to enable a third display. Unlike EHL's variant of DPLL4, the RKL variant behaves the same as DPLL0/1. And despite its name, the DPLL4 registers are offset as if it were DPLL2. v2: - Add new .update_ref_clks() hook. v3: - Renumber TBT PLL to '3' and switch _MMIO_PLL3 to _MMIO_PLL (Lucas) v4: - Don't drop _MMIO_PLL3; although it's now unused, we're going to need it very soon again for upcoming DG1 patches. (Lucas) v5: - Don't re-number TBT PLL and beyond, just use new RKL_DPLL_CFGCR macros to lookup the proper registers instead. Although renumbering the PLLs might be something we want to consider down the road, it opens a big can of worms right now since a bunch of places in the code have an assumption that the PLL table has idx==id and no holes. Renumbering creates a hole for TGL, so we'd either need to allow holes in the table or break the idx==id invariant, both of which are somewhat invasive changes to the design.
