[reactos] 09/20: [ISAPNP] Fixes and improvements for IRP handling

by Dmitry Borisov

https://git.reactos.org/?p=reactos.git;a=commitdiff;h=f15de1555420f87aa20c2… commit f15de1555420f87aa20c2cfaeb07a1e46846e350 Author: Dmitry Borisov <di.sean(a)protonmail.com> AuthorDate: Thu Mar 4 18:48:43 2021 +0600 Commit: Dmitry Borisov <di.sean(a)protonmail.com> CommitDate: Sun Jun 20 19:24:26 2021 +0600 [ISAPNP] Fixes and improvements for IRP handling - Implement device removal. - Finish the Read Port special handling introduced in 21514e473f5. - Gracefully handle low memory situations. - Implement IRQ translator. - Correctly stub power IRP handling. - Remove unneeded dispatch routines; implement WMI IRP handling. - Do not handle requests like WRITE_CONFIG. - Add a signature member to device extensions to make checks clearer. --- drivers/bus/isapnp/CMakeLists.txt | 1 + drivers/bus/isapnp/fdo.c | 166 +++++++++++++++++---- drivers/bus/isapnp/interface.c | 73 ++++++++++ drivers/bus/isapnp/isapnp.c | 295 ++++++++++++++++++++++++-------------- drivers/bus/isapnp/isapnp.h | 80 +++++++++-- drivers/bus/isapnp/pdo.c | 292 +++++++++++++++++++++++++++---------- 6 files changed, 682 insertions(+), 225 deletions(-) diff --git a/drivers/bus/isapnp/CMakeLists.txt b/drivers/bus/isapnp/CMakeLists.txt index 0d91dbf2691..6b8a6747546 100644 --- a/drivers/bus/isapnp/CMakeLists.txt +++ b/drivers/bus/isapnp/CMakeLists.txt @@ -4,6 +4,7 @@ list(APPEND SOURCE pdo.c fdo.c hardware.c + interface.c isapnp.h) add_library(isapnp MODULE ${SOURCE} isapnp.rc) diff --git a/drivers/bus/isapnp/fdo.c b/drivers/bus/isapnp/fdo.c index 7b32e790246..5d61c8b2dc4 100644 --- a/drivers/bus/isapnp/fdo.c +++ b/drivers/bus/isapnp/fdo.c @@ -4,6 +4,7 @@ * PURPOSE: FDO-specific code * COPYRIGHT: Copyright 2010 Cameron Gutman <cameron.gutman(a)reactos.org> * Copyright 2020 Hervé Poussineau <hpoussin(a)reactos.org> + * Copyright 2021 Dmitry Borisov <di.sean(a)protonmail.com> */ #include "isapnp.h" @@ -16,14 +17,22 @@ CODE_SEG("PAGE") NTSTATUS IsaFdoStartDevice( _In_ PISAPNP_FDO_EXTENSION FdoExt, - _Inout_ PIRP Irp, - _In_ PIO_STACK_LOCATION IrpSp) + _Inout_ PIRP Irp) { - UNREFERENCED_PARAMETER(Irp);
