2025-04-23PCI: Add CONFIG_MMU dependencyArnd Bergmann
It turns out that there are no platforms that have PCI but don't have an MMU, so adding a Kconfig dependency on CONFIG_PCI simplifies build testing kernels for those platforms a lot, and avoids a lot of inadvertent build regressions. Add a dependency for CONFIG_PCI and remove all the ones for PCI specific device drivers that are currently marked not having it. There are a few platforms that have an optional MMU, but they usually cannot have PCI at all. The one exception is Coldfire MCF54xx, but this is mainly for historic reasons, and anyone using those chips should really use the MMU these days.

2024-08-09drm/mgag200: Remove BMC outputThomas Zimmermann
Mgag200's BMC connector tracks the status of an underlying physical connector and updates the BMC status accordingly. This functionality works around GNOME's settings app, which cannot handle multiple outputs on the same CRTC. The workaround is now obsolete as the VGA-BMC connector handles BMC support internally. Hence, remove the driver's code and the BMC output entirely.

2024-07-19drm/mgag200: Add vblank supportThomas Zimmermann
There's no VBLANK interrupt on Matrox chipsets. The workaround that is being used here and in other free Matrox drivers is to program <linecomp> to the value of <vblkstr> and enable the VLINE interrupt. This triggers an interrupt at the time when VBLANK begins. VLINE uses separate registers for enabling and clearing pending interrupts. No extra synchronization between irq handler and the rest of the driver is required. v6: - clear VLINE status bit before registering IRQ (Jocelyn) v5: - disable all interrupts before registering IRQ (Jocelyn) - don't read from ICLEAR (Jocelyn) v4: - recreate patch on latest upstream - use devm_request_irq() for managed cleanup - fail if vblanking cannot be initialized - rename register constants (Sam, Emil) - clear interrupt before registering handler (Ville) - move <linecomp> programming into separate commit - set <linecomp> to <vblkstr> - fix typo in commit message v3: - set <linecomp> to <vdisplay> + 1 to trigger at VBLANK - expand comment on linecomp v2: - only signal vblank on CRTC 0 - use constants for registers and fields - set VLINECLR before enabling interrupt - test against STATUS and IEN in irq handler - coding-style fixes Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jocelyn Falempe <jfalempe@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Tested-by: Jocelyn Falempe <jfalempe@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240718104551.575912-7-tzimmermann@suse.de

The VRSTEN and HRSTEN bits control whether a CRTC synchronizes its display signal with an external source on the VIDRST pin. The G200WB and G200EW3 models synchronize with a BMC chip, but different external video encoders, such as the Matrox Maven, can also be attached to the pin. Only set VRSTEN and HRSTEN bits in the CRTC mode-setting code, so the bits are independent from the BMC. Add the field set_vidrst to the CRTC state for this purpose.

2024-02-26drm/mgag200: Add a workaround for low-latencyJocelyn Falempe
We found a regression in v5.10 on real-time server, using the rt-kernel and the mgag200 driver. It's some really specialized workload, with <10us latency expectation on isolated core. After the v5.10, the real time tasks missed their <10us latency when something prints on the screen (fbcon or printk) The regression has been bisected to 2 commits: commit 0b34d58b6c32 ("drm/mgag200: Enable caching for SHMEM pages") commit 4862ffaec523 ("drm/mgag200: Move vmap out of commit tail") The first one changed the system memory framebuffer from Write-Combine to the default caching. Before the second commit, the mgag200 driver used to unmap the framebuffer after each frame, which implicitly does a cache flush. Both regressions are fixed by this commit, which restore WC mapping for the framebuffer in system memory, and add a cache flush. This is only needed on x86_64, for low-latency workload, so the new kconfig DRM_MGAG200_IOBURST_WORKAROUND depends on PREEMPT_RT and X86.
