.SYNOPSIS
|
|
Stage the pf-vdisplay driver bundle the installer ships into -OutDir: the VENDORED signed pf-vdisplay
|
|
driver + the fetched nefcon device tool.
|
|
|
|
.DESCRIPTION
|
|
pf-vdisplay (our all-Rust IddCx virtual display) is built from packaging/windows/drivers/, and
|
|
the SIGNED output (pf_vdisplay.dll/.inf/.cat + punktfunk-driver.cer) is VENDORED under
|
|
packaging/windows/pf-vdisplay/ (signer punktfunk-ds-test — shared with the gamepad drivers — Class=
|
|
Display, HWID root\pf_vdisplay). Rebuild + re-vendor with
|
|
packaging/windows/drivers/deploy-dev.ps1 when the driver source changes, then copy the staged
|
|
pf_vdisplay.{dll,inf,cat} over the vendored copies. nefcon publishes a pinned release, so we fetch +
|
|
SHA-256-verify it (it provides nefconc.exe, used to create the root-enumerated device node — pnputil
|
|
can't).
|
|
|
|
Output (consumed by punktfunk-host.iss): -OutDir gets pf_vdisplay.inf/.cat/.dll + punktfunk-driver.cer
|
|
and nefconc.exe (x64). pack-host-installer.ps1 also drops install-pf-vdisplay.ps1 in.
|
|
|
